1.1 BiPAP® Vision™ Ventilatory Support System Overview
The BiPAP Vision Ventilatory Support System (BiPAP Vision), shown in Figure 1-1, is a microprocessor-controlled, positive pressure ventilatory assist system. The BiPAP Vision incorporates a user interface with multifunction keys, real time graphic displays, and integral patient and system alarms.
The BiPAP Vision features a centrifugal blower to generate airflow, as well as hardware and software platforms
that can be upgraded with an oxygen module and additional patient alarms. The system operates in the Continuous Positive Airway Pressure (CPAP), Pressure Support (S/T), and optional Proportional Assist Ventilation/Timed (PAV/T) modes.
The BiPAP Vision contains a variety of integrated safety and self-diagnostic features. All system functions are
checked at start-up and during operation. Errors are reported by visual and/or audible indicators.
Pressure regulation is achieved by monitoring proximal airway pressure and adjusting flows accordingly to
ensure that the proximal pressure equals the set pressure.

3.1 BiPAP Vision Ventilatory Support System
The BiPAP Vision is a microprocessor-controlled, positive pressure ventilatory assist system. The
system’s integral air intake filter draws in ambient air which is then pressurized by the system’s centrifugal blower assembly. The In-Line Flow Restrictor (ILFR) valve and Pressure Regulation Valve (PRV),
which are both located in the blower discharge airway, regulate total flow and pressure at the blower
discharge system. An oxygen module can be installed to add a controlled source of supplemental oxygen,
up to 100%, to the patient.
The Pressure Control (PC) board continuously monitors the readings from the Airflow Module (AFM) of
total gas flow, temperature, generated pressure, and patient circuit pressure to ensure prescribed therapy
to the patient. The PC board transmits process data to the Main Control (MC) board which then provides
overall control of the BiPAP Vision, including conveying instructions to the PC board regarding required
valve stem position and blower speed.
The unique design and operation of the ventilator makes it especially suited for mask applications.
Designed with the BiPAP Auto-Trak SensitivityTM feature that automatically adjusts to changing circuit
conditions, the ventilator is capable of ensuring optimum patient-ventilator synchronicity despite changes
in breathing patterns and circuit leaks. (Refer to the BiPAP Vision Clinical Manual.)
A liquid crystal display (LCD) screen is mounted on the front enclosure of the BiPAP Vision. The LCD
and the Display Control (DC) board provide the primary user interface with the ventilator, including the
visual presentation of data, control features, and visual and audible presentation of alarm conditions. The
user interacts with the ventilator through the touch pad and rotation of the rotary encoder while observing the results of this input on the display. The information provided on the display varies depending on
the state of the ventilator and / or the operations being performed.
The BiPAP Vision incorporates a number of safety features and self-diagnostic systems. System internal
functions are checked automatically at start-up, and periodically throughout normal operation. An
audible and visual alarm announces failures of principal subsystems. Integrated patient alarms are also
provided and are announced on a visual message display area as well as with an audible tone.
The following sections of this chapter describe in more detail the major subsystems and components that
make up the BiPAP Vision and its basic theory of operation.

3.2 Power Supply Subsystem (PSS)
The PSS supplies the Main Control (MC), Pressure Control (PC), and the Display Control (DC) with the
proper DC supply voltage. Safety features designed into the circuitry include an overvoltage disconnect,
low voltage supply detect, and line loss detect. Other features include “power-on” indicator voltage,
circulation fan power, and an On/Off switch connection.
Figure 3-2
PSS Block Diagram
1045049
Power Supply Subsystem (PSS) (Continued)
3.2.1 Input Range
The BiPAP Vision can operate with an AC input of 100, 120, 230, or 240 VAC (±10%) depending on the
model.
3.2.2 DC Supply
The output DC supply is fused at 30 amps and delivers between 20.6 VDC and 35 VDC with a maximum
ripple of 1 vpp (peak-to-peak voltage) to the MC, PC, and DC.
3.2.3 Overvoltage Disconnect
The overvoltage disconnect is used to remove the DC supply output when it exceeds 36 VDC and reconnects it when the level returns to an acceptable value.
3.2.4 AC Fail
The MC module monitors the level of DC supply voltage and the AC voltage output from the transformer
supply winding to determine if an AC fail condition exists.
Low DC supply detect – If the DC supply voltage drops to 19.38 VDC or lower (nominal), an AC fail
condition will be triggered.
Line loss detect – The AC voltage output from the transformer supply winding is monitored for a loss-ofcycle condition. Both legs of the winding are input to the monitoring circuitry. Whenever AC is lost, the
AC fail signal is activated.
3.2.5 Outputs
The PSS module also includes the following:
a.
Front panel “power-on” indicator voltage (J5)
b.
Circulation fan power (J4)
c.
On / Off switch (part of J2)

3.4.1 Microcontroller Interface
Programmable Array Logic (PAL) memory device decodes the chip selects in such a way that the program code is retrieved from the EEPROM and data is retrieved from the RAM. An additional PAL
provides the interface for the Intermodule Communications Bus (ICB). The microprocessor monitors:
oxygen and gas temperatures; Airflow Module (AFM) and Oxygen Module (OM) detection; In-Line Flow
Restrictor (ILFR), Pressure Regulation Valve (PRV), and oxygen valve DAC control voltage; blower DAC
control voltage; and power supply and reference voltages.
3.4.2 Blower Motor Drive
The complete motor controller includes closed loop speed control via analog circuitry. When the desired
speed and actual speed are known by the processor, the speed is adjusted by increasing or decreasing the
DAC converter output to achieve proper pressure and flow.
3.4.3 Pressure Regulation Valve (PRV) and In-Line Flow Restrictor
(ILFR) Drives
The valve drives have closed loop control via the microprocessor. The microprocessor reads seven
pressure, flow, and temperature sensors through the PC hardware, and receives prescription parameters
from the MC. The microprocessor then adjusts analog DAC voltages to control the PRV and ILFR valves
as required to meet the prescription.
3.4.4 Pressure Sensors
The PC module has two dual pressure sensors (MT1 and MT2) and a single sensor (MT3). They measure
patient pressure, unit outlet pressure, and barometric pressure. These sensors are subject to calibration
with their calculated slope and intercept values stored in the on-board EEPROM. MT3 is a backup outlet
pressure sensor that provides a redundant check of the primary outlet sensor located on the AFM.
NOTE:
Calibration is factory programmed and field adjustment is not required.
3.4.5 Error Line Control (ELC) Circuit
The ELC circuit is designed to simply detect a failure from, or signal a failure to, the MC and Display
Control (DC) modules. If the ELC line activates, only a power On / Off of the ventilator can clear this
latched circuit state.
3.4.6 Diagnostics Connector
The diagnostic connector (J3) interfaces with the microprocessor to view PC functions and system errors
on units from serial number 100500 to 105999, unless upgraded. For units greater than this, the diagnostic connector is on the rear of the unit.
1045049
3.5 Display Control Subsystem (DC)
The DC provides a means of displaying the operating mode, measured and calculated operating parameters, parameter setpoints, alarm limits, real-time graphics, and general status information. The DC also
provides the necessary user interface controls to modify the operating mode, parameter set points, alarm
limits, and graphical scales; and to reset or silence the audible alarm, and freeze or unfreeze graphics.
The displays and controls are described in more detail in the following subsections.

3.5.1 DC/DC Converter
The DC/DC converter reduces the +24 VDC bulk supply to a +5 VDC logic level. (S/N <106K)
3.5.2 Display Backlight and Contrast Adjustment
A serial 8-bit D/A converter provides two, 0 to +5 VDC which originate in the MCU for these controls.
3.5.3 Display Voltage DC/DC Converter
This adjustable negative voltage converter reduces the level of bulk supply voltage needed to operate the
Liquid Crystal Display (LCD) contrast control.
3.5.4 Cold Cathode Fluorescent Tube (CCFT) Inverter
The DC design has a DC to AC inverter that typically provides 390 VAC to the fluorescent tube in the
display through (J2). The current varies to adjust the brightness of the fluorescent tube.
3.5.5 Reference Voltage Checks
This circuit compares reference voltages to determine if they are at the appropriate level.
3.5.6 Power Failure Alarm Battery Enable
This control detects a power failure from the DC supply.
3.5.7 Alarm Battery Voltage Cutout/Check
The battery voltage cutout /check monitors the battery voltage level and cuts it out if it drops to a level of
approximately 3VDC.
3.5.8 Backup Battery/Charger
The DC contains a 3.6 V nickel cadmium rechargeable battery that operates the audible and visual alarm
indicators for at least 20 minutes, when fully charged, when the Error Line Control (ELC) is active, and
the DC supply has been removed. The battery output is compared to a reference voltage and the battery
is recharged as required through a charging circuit. If necessary, refer to page 5-12 to recharge the
battery.
3.5.9 Check Ventilator Light Emitting Diode (LED) Enable Current
Check
An internal test is performed to verify that the Check Ventilator LED current is acceptable.
3.5.10 Vent Inop LED Current Check
An internal test is performed to verify the Ventilator Inoperative LED current is acceptable.
3.5.11 Error Line Control (ELC) Circuits
The DC contains redundant error signaling circuitry to communicate error conditions among the subsystems. The circuitry’s redundant and diverse nature minimizes the chance of communication failures.
1045049
Display / Control Subsystem (D / CS) (Continued)
3.5.12 Error LED
The error LED indicates that an error condition was detected, and it illuminates to make unit diagnosis
easier.
3.5.13 Diagnostic Interface
The diagnostic connector interface (J5) interfaces with the MCU to provide a means for the DC to download diagnostic data to a terminal or PC.
3.5.14 EEPROM
A serial EEPROM stores the setpoints for the backlighting and contrast and also for the appropriate
diagnostic data.
3.5.15 LCD Controller
The DC circuit contains an LCD controller that interfaces with the display.
3.5.16 Debouncing / Keypad Matrix
The matrix keys are debounced and then the microprocessor scans the matrix to determine what key was
depressed.
3.5.17 Rotary Encoder Control
The rotary encoder control circuit detects relative position, direction, and speed of the rotary encoder, all
within one detent of movement.
3.5.18 Audible Alarm Activation
The audible alarm is activated by either an input from the ELC, the power fail circuitry, or the test alarm
signal from the MCU. It will also occur when the wrong key has been depressed, an adjustable parameter
has reached its limit, or the error signal has been activated.
3.5.19 Audible Alarm Current Check
An internal test is performed to verify the audible alarm current is acceptable.
3.5.20 “Power-on“ in Safe State
The DC contains circuitry that causes the hardware to “power-on” in a safe state; which is when the
backlight is off, the display is off, and the Intermodule Communications Bus (ICB) is terminated. When
the MCU determines that no Vent Inop error exists, it lets the unit resume operation under normal
operating conditions.
3.5.21 Watchdog and Low Voltage Reset
The watchdog function has to be periodically reset by the microprocessor if a time-out period has been
exceeded. This function is designed to reset the processor if the software gets lost. When a low logic level
is detected, the ELC will be activated resulting in a system shutdown.
1045049

3.6 Airflow Module (AFM)
The AFM is a submodule of the Pressure Control (PC). The AFM receives power from the PC and provides the following analog signals to the PAS:
a.
Gas flow indication
b.
Pressure indication
c.
Temperature indication
To provide indications accurate enough for system requirements, the AFM must be calibrated. Calibration data is stored in a nonvolatile memory that is part of the AFM. The flow, pressure, and temperature
indications are for the ventilator gas stream flowing through a “flow body” attached to the AFM circuit
board.
3.6.1 Flow Body
The flow body, with laminar flow element, is added to the ventilator gas stream, creating a small pressure
differential to short a fraction of the flow through the AFM sensor. Inlet, outlet, and pressure ports are
part of the flow body for tubing attachment to the AFM electronic sensors. Also, a hole is molded into the
flow body to position the temperature sensor. The body has molded feet for attaching it to the AFM
circuit board assembly.

Airflow Module (AFM) (Continued)
3.6.2 Analog Reference
The PC provides the AFM with power in the form of +12 VDC, –12 VDC, analog ground, +5 VDC, and
digital ground. An analog voltage reference supply is derived from the +12 VDC to power the pressure
and flow sensors so their bridge outputs can be factory calibrated.
3.6.3 Flow Indication
Total gas flow indication is provided by MT1. It is then amplified by an instrumentation amplifier, lowpass filtered, and sent to the PC board for conversion.
3.6.4 Pressure Indication
MT2, a precision compensated pressure sensor, provides unit outlet pressure indication. The sensor is
followed by a low-pass filter and a differential amplifier, and then sent to the PC board for conversion.
3.6.5 Temperature Measurement
The temperature is measured using a sensor inserted into a molded hole in the flow body. The BiPAP
Vision requires temperature indication to correct air density and detect an undesirable temperature rise in
the patient circuit.
3.6.6 Calibration
A data acquisition system, operating on a personal computer, is the control platform for AFM calibration
of temperature, pressure, and flow. Correction factors are derived and stored in the AFM module in an
EEPROM, with calibration accomplished by balancing the flow transducer bridge with an EEPOT. The
PAS uses temperature, pressure, and flow to correct for actual operating conditions. Once calibrated, the
AFM is interchangeable with other AFM assemblies.
NOTE:
Calibration is factory programmed only.
3.6.7 Module Detection
The PC must know the AFM is connected, since it is required for normal operation of the ventilator. An
extra line pulls a PC microcontroller line near zero volts. If the line is above two volts, the AFM is not
connected, and the PC will transition to the error state.

3.7 Oxygen Module (OM)
The OM is an optional submodule of the Pressure Control (PC). It receives power from the PC and
provides an analog signal to the PC for oxygen flow indication. To provide indications accurate enough
for system requirements, the OM must be calibrated. Calibration data is stored in a nonvolatile memory
that is part of the OM. The flow indication is for the ventilator pure oxygen stream flowing through a flow
body attached to the OM circuit board.

3.8 Description of Ventilator Modes
The BiPAP Vision comes standard with two operating modes: Continuous Positive Airway Pressure
(CPAP) and Spontaneous/Timed (S/T). A third, optional, Proportional Assist Ventilation/Timed (PAV/
T) is also available.
3.8.1 Continuous Positive Airway Pressure (CPAP)
CPAP provides a constant pressure level delivered over the complete range of the patient’s spontaneous
breathing cycle. Pressure is controlled and maintained. Flow is available to meet changing patient
demands and automatically compensate for leaks. The mode delivers the prescribed level of pressure
that has been set with the CPAP control (Range: 4 to 20 cm H2O).
3.8.2 Spontaneous/Timed (S/T)
The S/T mode provides either pressure support during spontaneous breaths or time-triggered, pressurelimited, time-cycled machine breaths.
Spontaneous Breaths
Two pressure levels are set: an EPAP level (range 4 to 20 cm H2O) to establish a baseline pressure and an
IPAP level (range 4 to 40 cm H2O) that determines the amount of pressure support delivered with each
breath (PS = IPAP– EPAP). During the inspiratory phase, the BiPAP Vision responds as necessary to
satisfy the patient’s flow requirements while maintaining the preset IPAP pressure. Under these conditions, the patient is active in determining inspiratory time and tidal volume. The delivered tidal volume
will be dependent upon the pressure differential between the IPAP and EPAP levels, patient effort, and
the combined resistance and compliance of the circuit and the patient. If the patient does not actively
participate, the BiPAP Vision responds appropriately.
Timed Breaths
The S/T mode can also provide a time-triggered, pressure-limited, time-cycled machine breath, when the
spontaneous respiratory rate drops below the Rate control setting. If the ventilator does not detect a
spontaneous trigger within the interval determined by the Rate control setting, it will activate a timetriggered machine breath and deliver the IPAP level. Machine breaths are not synchronized with patient
effort, and once triggered to IPAP, the balance of the cycle is determined by the Timed Insp. Control
setting. A maximum Timed Inspiratory setting of 3.0 seconds can be set, as long as the I:E Ratio does not
exceed 1:1, as determined by the Rate setting. For example, see Figure 3-12. If the Rate control is set at 10
BPM, the total respiratory cycle is six seconds. If a spontaneous trigger occurs before the six-second cycle
time has elapsed, a spontaneously-triggered, pressure support breath occurs, a timed trigger will not
occur, and the timer is reset for a new six second interval. If a six second interval passes without a
spontaneous trigger, a timed trigger will be initiated and IPAP will be delivered for the duration of time
set by the Timed Inspiration setting.

3.9
Nurse Call/Remote Alarm Feature Operation (for s/n units
greater than 106000 only)
The unit will activate a remote signal for system shutdowns, patient alarms, and Loss of AC Power conditions which inhibit therapy. Note that a Check Vent condition does not activate the nurse call signal. The
nurse call signal can be silenced via the Alarm Silence key for the same amount of time that the audible
alarm on the Vision is silenced (two minutes). The signal can also be cleared by selection of the Alarm
Reset key. The nurse call signal will automatically terminate when a patient alarm self-cancels.
The Nurse Call/Remote Alarm feature is meant to be a backup with the main Vision alarm system being
the primary alarm/alert mechanism.
The Nurse Call or Remote Alarm signal is generated on the MC board and then can be connected to a
hospital nursing station. This signal is opto-isolated and used to switch a relay to provide open or closed
contacts to the remote station circuit. The arrangement of the two jumpers (JP1 and JP2) on the MC determine the output configuration that is utilized by a common connector on the rear panel of the Vision.
The Nurse Call Adapter (RI P/N 1014280) along with the Nurse Call Cable (RI P/N 1003742) can be used
to connect the Vision to a Nurse Call station.
The jumper configuration on the MC circuit board can be selected to meet requirements according to the
following table. Refer to the photo for jumper location.

3.10
BiPAP Vision Patient Disconnect Alarm Description of
Operation
The patient disconnect alarm (“Disconnect”) is based on the flow limit control algorithm in the Vision. The mitigation for the Disconnect alarm is to put the unit into flow limit control. This same action is done when the user selects
the Standby key.
3.10.1 Detection
The unit determines that a patient is not connected to the circuit anymore based on flow for the given pressure. This
is implemented via a look-up table, with a flow entry for every generated pressure. The range of flows is 95 to 180
LPM, with 180 LPM being the low limit for any pressure above 9 cmH2O. If the unit detects flow greater than the
threshold at any given pressure for more than 10 seconds (3 seconds in for software earlier than 13.2), the unit puts
itself into the Flow Limit Control state. In this state, the unit attempts to limit the flow coming out of the mask in
order to make putting the mask back on the patient easier and more comfortable for the patient.
Also, for safety concerns, the oxygen valve closes to discontinue oxygen delivery during this condition.
When the Standby key is selected by the user, the unit automatically enters the FLC state, regardless of the flow at
the time the Standby key is selected.
In order to limit the flow, the unit drops the pressure to 4 cmH2O. The algorithm was enhanced to work with the Full
Face Mask a while ago. The Full Face Mask has a flap that will close the patient circuit and open the mask to
atmosphere upon loss of flow and pressure. This flap must be kept in a position during FLC so that the patient
circuit is not occluded. This allows the unit to detect when the patient is reconnected. The enhancement to the
algorithm consists of the pressure being slowly increased to keep the flow at 160-170 LPM. The pressure level is
limited to 10 cmH2O for software 11.2 and 11.3 (15 cmH2O for software 11.3a and higher), regardless of how much
flow is being generated. Therefore, the unit will either output 160-170 LPM at some pressure or will be limited to
some lesser flow at 10 cmH2O for software 11.2 and 11.3 (15 cmH2O for software 11.3a and higher).
3.10.2 Termination
There are two termination stages to FLC. During the first stage, as the pressure is being increased from 4 cmH2O to
its maximum of 10 cmH2O for software 11.2 and 11.3 (15 cmH2O for software 11.3a and higher), FLC will be
automatically terminated if the unit detects negative flow (i.e., the patient breaths back into the unit). This pressure
increase takes about 10 – 12 seconds for software versions earlier than 13.2, depending on how soon the flow set
point is reached. There have been two enhancements in software version 13.2 in this area. The first is that the
pressure is increased faster (1 cmH2O per 40 ms instead of the previous ¼ cmH2O per 40 ms) to shorten the amount
of time in stage one. The second change concerns the flow range processing. In software versions earlier than 13.2,
when the pressure is dropped to 4 cmH2O and the flow is greater than the desired flow range (160-170 LPM), the
flow limit algorithm attempts to decrement the pressure to get the flow into that desired range. In software version
13.2, that was changed to immediately enter stage 2 under that condition.
1045049
3-21
3-22
Once either the flow set point or the maximum pressure is reached, the unit will automatically terminate
FLC for either the detection of negative flow or if flow varies from the current flow by more than 40 LPM
in software versions prior to 13.2 and 20 LPM for software version 13.2. For instance, if the 160-170 LPM
set point has been reached, the unit will terminate FLC if the flow drops below 120 LPM or goes above
210 LPM in older software and 140-190 LPM in the new software.
If the flow set point has not been reached, the current flow at 10 cmH2O for software 11.3 and 11.3 (15
cmH2O for software 11.3a and higher) is used as the set point. For instance, if only 80 LPM can be
reached at 10 cmH2O for software 11.3 and 11.3 (15 cmH2O for software 11.3a and higher), the thresholds
for automatic termination of FLC will be 40 LPM and 120 LPM in older software and 60-100 LPM in new
software.
This allows FLC to be terminated without the patient necessarily breathing back into the machine but by
the simple act of refitting the mask to the patient.
The Standby condition, besides being terminated automatically by the above methods, can also be
manually terminated by reselecting the highlighted Standby soft key on the Monitoring screen.
When FLC is terminated during a “Disconnect” alarm period, the alarm is self-cancelled. That means
that the audible component of the alarm is silenced but the visual component of the alarm remains
displayed on the screen. That can be cleared by selecting the Alarm Reset key.
Note: During FLC, the oxygen parameter setting reduces to 21%, regardless of the setting.

5.8 Internal Alarm Battery
5.8.1
Battery Function
The BiPAP Vision contains an internal NiCAD battery located on the DC (P/N 1012819) to activate the
Ventilator Inoperative visual and audible alarm indicators if an error occurs. A fully charged battery can
maintain the audible alarm for up to 20 minutes.
5.8.2
Low Battery Condition
The NiCAD battery can lose its charge if the BiPAP Vision is not used for an extended time. In a typical
environment, a fully charged battery can be stored approximately six months before losing its charge, but
the discharge rate depends heavily on temperature.
NOTE:
The BiPAP Vision internal alarm battery should be charged prior to use if it has been
stored for longer than three months.
If the battery voltage is too low to support the alarm indicators, the Check Ventilator visual (Eye icon) and
audible alarm indicators will activate. The time that the audible alarm operates may be short due to the
low voltage of the battery. The BiPAP Vision also generates error code 205.
To check the error code:
Step 1
Silence the audible alarm component by pressing the Alarm Reset key.
The audible component will not sound again.
Step 2
Press the Monitoring hard key if you are not already in the Monitoring screen.
Step 3
Press the Options soft key.
Step 4
In the Options screen, press the Error soft key.
Check vent error codes are displayed in the top line of the Options/Message area.

5.8.3
Charging the Internal Battery
There are two methods used to recharge the NiCAD battery on the DCS circuit board that is used to sound the
audible alarm, fast charge and normal.
1. Fast Charge Method (Check Vent/Error 205 Being Displayed)
A fast charge will be initiated at first time initialization and when a low internal battery error is detected. Fast charging
is available when the unit is in the Setup Screen and when it is providing therapy (i.e., the unit can sit in the diagnostic mode and still fast charge). Fast charge time is 6 hours to sufficiently charge the battery to support the audible
alarm for 20 minutes.
If the unit is powered off during a fast charge sequence, the sequence will pick up where it left off when the unit is
powered back on unless a low battery error is detected during the start-up testing (i.e., the unit was off long enough
to discharge the battery). In that case, a new 6-hour fast charge sequence will be initiated. The functionality of the
Check Ventilator error 205 remains unchanged - the error code will be able to be cleared approximately 1 minute after
the status indicates a good battery.
Note:
If the status never indicates a good battery (i.e., the battery is actually bad and will not take a charge),
the fast charge sequence will run continuously. The user will be able to detect this by not being able to
clear the 205 error even after a full fast charge cycle.
Charging Process:
1.
2.
3.
4.
5.
Remove the unit from patient use.
Plug the unit into an AC source and start the unit. The Self Diagnostics will begin.
Allow the unit to remain in the Exhalation Port/Language Screen.
Or, allow the unit to be in therapy or Standby mode. Press the alarm reset to silence the audible alarm.
Leave in one of these conditions for approximately 6 hours to fully charge the battery.
2. Normal Method (No Check Vent/Error 205)
If there is no Check Vent error 205, the charging circuit will continue to charge the battery on a regular basis while in
the Test Exhalation/Language screen or during therapy use. It will take approximately 24 hours to fully charge the
battery to support the audible alarm for up to twenty minutes.
Charging Process:
1.
2.
3.
4.
5.
Remove the unit from patient use.
Plug the unit into an AC source and start the unit. The Self Diagnostics will begin.
Allow the unit to remain in the Exhalation Port/Language selection screen.
Or, allow the unit to be in therapy or Standby mode.
Leave in one of these conditions for approximately 24 hours to fully charge the battery.
1045049
Charging Verification:
1.
2.
3.
A minimum of two hours is required to charge a fully discharged battery to a voltage at which the alarm will
not be activated. At this time, the unit can be operated and will continue to trickle charge the battery while it is
in operation.
Press Monitoring to begin operation.
Wait two minutes to determine if the Check Vent alarm activates with an error 205 in the Error Message screen.
If not, then the unit is ready for use.
CAUTION:
Prolonged storage of the BiPAP Vision at high temperatures, above 80 ºF (27 ºC) can
result in premature battery failure. Failure to recharge a battery when it is being stored for
long periods will cause a loss of battery life, activate the Check Ventilator alarm, and
generate error code 205.

6.2 Description of System Alarms
The BiPAP Vision incorporates self-diagnostic testing capabilities and a number of safety features. All
system internal functions are checked automatically at start up and periodically throughout operation. The
microprocessors continuously obtain readings from internal sensors to monitor machine functions and
operating conditions. Device malfunctions or abnormal operating conditions are analyzed and reported
according to the level of severity. Two primary alarm functions, Check Ventilator and Ventilator Inoperative, are available to identify a system malfunction. Patient Alarms are displayed on screen when activated.
6.2.1 Patient Alarm Indications
All alarms contain an audible and visual element. In the event of an alarm condition, the audible alarm
sounds and the screen changes to show the alarm condition in the Mode/Message Area. See Figure 6-1.

Description of System Alarms (Continued)
6.2.2 Patient Alarm Silence and Reset
The audible indicator of most alarms is self-cancellable if the patient alarm condition is corrected. The user
can silence the audible indicator by pressing the ALARM SILENCE hard key. The ALARM SILENCE hard
key turns off the audible alarm for two minutes. Additional pressing of the ALARM SILENCE hard key has
no effect on the alarm. When the alarm silence is active, the message “Alarm Silenced” appears in the
Mode / Message Area for the duration of the silence period. Any new alarm condition that occurs, except
for an Apnea alarm, during the silence period will provide a visual alert, but will not trigger the audible
alarm.
The visual patient alarm indicator in the Mode / Message Area is cancelled only when the ALARM RESET
hard key is pressed. The ALARM RESET hard key cancels the alarm silence period and resets the visual
indicators. The alarm immediately reactivates if the condition causing the alarm has not been corrected.
1045049
6.3 Alarm Indicators
6.3.1 Vision Ventilator Inoperative Indicator
Purpose:
Alerts the user to a machine malfunction by
illuminating the red “Wrench” icon on the display
panel and activating an audible alarm. The ventilator
immediately powers down and opens the internal
valves allowing ambient air to be drawn through the
ventilator for unimpeded spontaneous breathing. The
audible and visual alerts remain active and cannot be
silenced until the On / Off Switch is placed in the
OFF position.
Active:
At all times.
6.3.2 Check Ventilator Indicator
Purpose:
Alerts the user of a potential abnormal operating
condition by illuminating the yellow “Eye” icon on the
display panel and activating an audible alarm. The
audible alarm can be temporarily silenced with the
ALARM SILENCE hard key. However, the visual
indicator cannot be reset and remains illuminated until
the error is corrected. The ventilator continues to
operate during a “Check Ventilator” condition.
Active:
At all times.

8.1 Overview
The following is a summary of the testing and calibration procedures detailed in this chapter.
8.2
Recommended Testing after Part(s) Replacement
Defines the recommended testing to perform on the unit after removal and
installation of a replacement part. The testing reflects the minimum required to verify
system performance.
8.3
Exhalation Port Test
Characterizes the circuit by analyzing the leak rate of the exhalation port.
8.4
Total Operating Hours Transfer Procedure
Transfers the current Total Operating Hours for a unit when
replacing the Main Control Subsystem (MC), or the memory battery.
8.5
Blower/Valve Calibration Procedure
Provides instructions for calibrating the Blower and Valves of the unit
after major component replacement.
8.6
Performance Verification
Verifies that the BiPAP Vision user interface is functioning properly. It is not
intended to verify specifications, only the operational features are tested.
8.7
Run-In Cycle Procedure
This procedure is to be used after servicing the BiPAP Vision as called out in the
Testing after Part(s) Replacement on page 8-3 and 8-4. The unit will cycle for one half hour
with specified operating parameters to qualify the repair after a component has been

8.3 Exhalation Port Test
Purpose
The Exhalation Port Test characterizes the circuit by analyzing the leak rate of the exhalation port. During
the test, the system learns the intentional exhalation port leak over the complete pressure range. The
learned leak value is then stored in system memory and is used to perform leak calculations and provide an
accurate display of patient leak, minute ventilation, and tidal volume in the Data Display Area. When a test
is performed successfully, the Data Display shows the unintentional leak. The display will appear as “Pt.
Leak” in the Data Display Area. If the test is not performed or cannot be completed successfully, the system
is unable to accurately know the intentional leak and will display the total leak value (intentional + unintentional). The display will appear as “Tot. Leak” in the Data Display Area.
NOTE:
The Exhalation Port Test should be performed after servicing to ensure the accuracy of
estimated tidal volume and minute ventilation readings. Accurate minute ventilation
readings are necessary to ensure the accuracy of the low minute ventilation alarm when
it is set below 3 L/min.
NOTE:
The Exhalation Port Test is recommended before each use, with circuit changes, with
changes in the exhalation port, or after servicing. Completing the test ensures the
accuracy of some displays and alarms.
Equipment Set-up
• First Install a 6’ smooth inner lumen tubing, then a whisper swivel, and then a pressure pickoff port onto the unit outlet.
• Connect a pressure line from the pick-off port to the pressure connection on the Vision unit.
• Occlude the outlet.
Procedure
Step 1
Plug in the power cord. The Main Power indicator will illuminate.
Step 2
Turn the main power switch to the On position and wait for the unit to complete the

BiPAP Vision Oxygen Module Testing for S/N 1007401-108343
Note: This test should only be performed once for affected units. If the Oxygen Module has been replaced with
a new type, or if your unit does not have a serial number on the oxygen module label, this test does not need
to be performed.
Purpose:
1. To perform an additional test on BiPAP Vision units from serial number 107401 to 108343
(inclusive). This procedure must be done the first time a Vision that falls within the above listed
serial number range is returned for service for any reason. This procedure is to be performed
after the unit passes system final test found in the service manual.
2. This procedure must also be performed on any Oxygen Module repair kit from serial number
300000 to 301249 (inclusive) that has been installed into any unit. The serial number is located
on the cover. Repair parts 582142 and 1004977 are made up of these serial numbers, along with
the production units listed above.
This test will verify the ability of the oxygen delivery subassembly to adequately supply the required flow
needed to yield a specified oxygen concentration at the maximum unit flow rate. Some of these may have
had a vendor assembly problem. Any faults will require the replacement of the Oxygen Module assembly.
Test Equipment:
Same as used with oxygen testing found in step K of the System Final Test.
Test Setup:
See figure 8-8, except substitute the flow restrictor in the circuit for the test lung. Begin with a small leak.
Procedure:
1.) Turn the unit on.
2.) After the System Self Test completes, press MONITORING.
3.) Press PARAMETERS button and set the following unit parameters:
IPAP = 40 cm H2O
EPAP = 20 cm H2O
RATE = 10 BPM
TIMED INSP. = 3.0 sec
IPAP RISETIME = .05 sec
O2% = 21%
1045049
8-27
8-28
4.) Slowly open the flow restrictor and verify the flowmeter reads a minimum of 130 LPM for four
consecutive breaths during the IPAP portion of the cycle. If the unit activates the “Disconnect”
alarm, it may be necessary to adjust the flow restrictor valve to a lower flow and slowly re-open to
reach this flow rate.
5.) Set the O2% parameter to 100% and wait for oxygen analyzer reading to stabilize.
6.) For the unit to pass, the oxygen analyzer reading must remain between 90% and 109% inclusive for
four consecutive breaths. If any unit fails, the Oxygen Module subassembly must be replaced and the
unit retested.
7.) When complete, set the unit parameters as follows:
IPAP = 15 cm H2O
EPAP = 5 cm H2O
RATE = 10 BPM
TIMED INSP. = 1.0 sec
IPAP RISETIME = .05 sec
O2% = 21%
8.) Press MONITORING button.
9.) Close the oxygen tank valve.
10.) Turn power off and disconnect test equipment.
11.) Test Complete.
1045049
K. Oxygen Module Operation
Note: To perform this test it is necessary that the Vision unit being tested have at least 11.8 / 12.4 / 13.4 software. If
your Vision unit has earlier software, it is mandatory that it be upgraded before performing this test.
Note: See Figure 8-8 for assistance in connecting oxygen analyzer.
WARNING:
Oxygen supports combustion. Do not use oxygen while smoking or in the presence of an open
flame.
WARNING:
Never use the analyzer to measure gas with a high oxygen content following use on air with an oil
vapor content. The oil vapor will contaminate the tubing and may result in a fire on contact with
high oxygen levels.
Oxygen Module Test Procedure
Step 1
Prior to performing this test, a visual inspection should be made of the internal components of the
oxygen delivery system including tubing, to ensure that there are no faulty items.
Step 1A
Connect the 6 foot smooth inner lumen tubing from the outlet of the Vision, to the Whisper Swivel,
then to a pressure pick-off port (O2 port) and then to the TTL Lung (or equivalent). A small length of
tubing (approximately 6 inches) may be needed between the pressure pick-off port and the test lung.
Connect the oxygen analyzer cell in the patient circuit.
Put the pressure tubing from the pick-off port to the unit’s patient pressure connection.
Or, Using a “T” connector, connect the pressure pick-off port, the unit’s patient pressure connection
and the oxygen analyzer inlet together, whichever applies.
Set the test lung to have a compliance of 0.04 and a parabolic resistance of 20.
Step 2
Turn on the Vision unit.
Step 3
On the unit, press Parameters and set the following unit parameters.
IPAP = 20 cm H2O
EPAP = 4 cm H2O
RATE = 15 BPM
Timed Insp. = 1.0 sec
IPAP Risetime = .05 sec
O2% = 21%

Step 4
Press Monitoring. Ensure that the tidal volume reading on the Vision (Vt) is at 500 ml, +/- 20 ml (480 to
520 ml). If not raise or lower the IPAP pressure until the proper tidal volume reading is obtained.
Step 5
Connect the O2 line to the Oxygen Module. Open the O2 cylinder valve. Ensure that the O2 regulator
is set at 50 psi.
Step 6
Wait for the Oxygen Analyzer to stabilize and verify that the reading is 18% to 24%.
Note: Readings should be stable after 8 to 10 breaths. Some variance in the reading may occur,
depending on the quality of the analyzer being used.
Step 7
Press Parameters then set % O2 and adjust for 30% O2 level. Wait for the Oxygen Analyzer to stabilize
and verify that the reading is between 27% and 33% (inclusive). If the tidal volume reading on the
Vision falls out of the acceptable range, adjust the IPAP pressure until the tidal volume falls within the
acceptable range before taking the reading.
Step 8
Set the O2 to 100%.
Step 9
Close the O2 cylinder valve. Disconnect the Oxygen hose from the back of the Vision.
Step 10
The unit should alarm for no O2 Flow at 15 Breaths or less.
Step 11
Reconnect the Oxygen hose to the back of the Vision and Open the O2 cylinder valve, set the O2 to
40% and press Alarm reset. Verify that no alarms exist after 8 breath cycles.
Step 12
Wait for the Oxygen Analyzer to stabilize and verify that the reading is between 36% and 44%
(inclusive). If the tidal volume reading on the Vision falls out of the acceptable range, adjust the IPAP
pressure until the tidal volume falls within the acceptable range before taking the reading.
Step 13
Set the unit for 60% O2. Wait for the Oxygen Analyzer to stabilize and verify that the reading is
between 54% and 66% (inclusive). If the tidal volume reading on the Vision falls out of the acceptable
range, adjust the IPAP pressure until the tidal volume falls within the acceptable range before taking
the reading.

1045049
10-7
From the repair kit 1004713 or 1000356 (PAV):
1. Locate the EPROMs (version 12) and place them into their respective locations on the MC and
PC boards.
2. For non-PAV/T units, remove the original Alarm PAL located in U41 in the MCS and place it in
the new MC board. For PAV/T units, install the PAL provided with upgrade kit 1000356 into U41
in the MC board.
3. Remove the DCS from the front panel. Install the DCS EPROM into its respective location.
4. Locate the independent connector supplied with the kit. Insert it into the DCS next to the original
ICB connector that is in the center of the board. It should be placed so that the keying (single open
slot in the plastic body of the connector) is facing downwards. Solder in place. This will allow for
the new ICB cable to be located so that the ribbon cable is downwards towards the bottom of the
unit.
5. Re-install the original DCS back onto the front enclosure.
6. Install the 6-32 nut and one of the aluminum spacers onto the MC board with the spacer located
on the component side of the board and the nut on the other side. The mounting hole is located by
the power cable connection near the center of the board.
7. Install the MC board into the bottom enclosure. Use the existing nylon “snap” standoffs to be
placed where the original ones were removed, except put the new 8-32 x 3/8 screw in the
mounting hole with the ground plane around it, which is located along the transformer edge of the
MC board.
8. Also for the MC, install new nylon “snap” standoffs in the front left and back left MC mounting
holes. Put one of the three nylon standoffs between these two. Put one of the other two nylon
standoffs in the rear behind the power supply connector and the third one opposite of this in the
front of the MC board.
9. Place the original DC ground wire and screw is to put into the mounting hole with the ground plane
around it on the front left side of the MC board.
10. Temporarily install the Ribbon cable, 1004699. This is not part of the kit, but should be kept on
hand as part of the service tools needed to repair upgraded BiPAP Vision units s/n<106K. It will
be left in only for testing purposes and must be removed afterwards.
1045049
10-8
Installation/Upgrade (continued)
11. Install the PC board onto the MC board standoffs making sure that the power connection near the
center of the board, and the other similar connector (testing and error data) located in the front
right of the board are fully seated. Also make sure that all of the nylon “snap” locks are fully
engaged.
12. Mount the second aluminum standoff onto the location near the center of the PC board where the
first aluminum standoff from the MC board can be seen.
13. Connect the blower, valves, circulation fan current sense, Oxygen Module ribbon cable, and the
new ICB cable to the appropriate PC connection points.
14. Locate the new AFM to PC ribbon cable and install it in place. Put this on the PC connection J4
to the AFM. The other is connected to J6 for the OM ribbon connection.
15. Connect the new power supply cable to the PSS connection. Note that the new cable has 6
inches between the one end connector and the one in the middle. Connect this middle connector
to the power connection on the PC board. Make a counterclockwise loop in the remaining part of
the cable that will connect to the DCS board. Using the 6-32 x ¼ inch screw and cable clamp
from the kit, attach the power supply cable to the center aluminum standoff in the center of the PC
board. This will allow the cable to be secured, but also allow some movement of the cable during
front panel removal.
16. Remove the 7 inch piece of pressure tubing that connects from the “T” fitting on the AFM that
originally connected to the pressure sensor on the PAS board.
17. Locate the 3 inch piece of pressure tubing in the kit and place one end on the AFM “T” connection and the other end to the redundant pressure sensor. This is the sensor located nearest to the
AFM module.
18. Re-install the blower, blower muffler and inlet tubing (if all or any of these were removed). Connect the blower connector to the PC board.
19. Re-install the front enclosure, making sure that all the proper connections are secured in place.
The patient pressure tubing will go from the front enclosure to the middle pressure sensor, port on
the right side.
20. Make sure all required connections are correctly made. Just a reminder to double check your
work.
1045049

B.1 Schematic Statement
B.1 Schematic Statement
Schematics are supplied with this manual in direct support of the sale and purchase of this product.
The schematics are proprietary and confidential. Do not copy the schematics or disclose them to third
parties beyond the purpose for which they are intended. Patents are pending.
The schematics are intended to satisfy administrative requirements only. They are not intended to be used
for component level testing and repair. Repairs and testing are supported only at the complete board level.
Respironics does not recommend component repair of the BiPAP Vision. The circuit boards in the BiPAP
Vision are multilayer boards. Due to the very small trace size, extreme care must be used when replacing
components to prevent permanent nonrepairable damage to the circuit board. Components are surface
mounted and require special hot air jet soldering and desoldering equipment. Most of the work should be
done under a microscope set at 25 times magnification. Use of regular soldering equipment will damage
the board and void any applicable warranty.
The schematics are of the revision level in effect at the time that this manual was last revised. Prior
revisions may be obtained upon request.
