Chapter 2 Description
Hardware
The PC-VetGard is a battery operated, Bluetooth enabled, wireless, multi-parameter patient
monitor providing ECG, Sp02, Respiration and Temperature information and displaying realtime waveform and digital information on a computer monitor. Each VetGard includes the
following sensors:
™ A chest probe with three build-in metallic electrodes for ECG screening. When placed
over the heart, accurate rate and rhythm information is derived and if oriented to
approximate the Lead II axis, an estimation of true Lead II amplitude can be achieved.
™ A set of three clip electrodes that, when attached to the legs of the patient as described,
provide Lead II information.
Note: Since it is not always possible to obtain an adequate signal using the
chest probe, clip leads may be required when monitoring some patients. Clip
leads can also be used to continuously monitor the ECG signal during surgery or
for short term critical care monitoring.
3. Select “File” from the top toolbar and replace the check mark at “Connect to VetGard”
to enable automatic connection to the VetGard. NOTE: The VetGard will not
connect to your computer unless the check mark is replaced.
™ Two internal esophageal probes to monitor ECG and temperature of the anesthetized
patient. Three electrodes are affixed to a flexible plastic tube that is inserted into the
esophagus and positioned over the heart with the distal electrode positioned behind
the left ventricle and the second electrode behind the left atrium. The third electrode
is ground. Each esophageal probe includes a temperature sensor for the accurate
detection and display of core body temperature
Computer Video Resolution
™ A cable yoke and set of 3 leads with spring clips for attachment to pre-gelled,
disposable electrodes for long term monitoring.
2. Type in desired information and press OK.
NOTE: Ensure that the resolution on your computer display is set to 1024 x 768 so

The VetGard is equipped with an integral wireless Bluetooth radio transmitter. Bluetooth
enables the wireless transmission of information, including real-time patient data,
between the VetGard and a Bluetooth enabled Windows based computer.
All functions not requiring keyboard input can be controlled from the VetGard front
panel or. The Windows display toolbar, however commands are only active if a wireless
connection between the VetGard and the computer is established.
Bluetooth operates at approximately 2.4 GHz. and steps up and down frequency
constantly making the VetGard free of interference including the radio frequency
interference common in hospital and clinic settings. Bluetooth transmissions are omnidirectional, operate at low power and travel through walls and around corners to a radius
of 50-100 ft. It is not necessary to aim the VetGard at the computer or printer to initiate
commands. The computer and/or printer can be in another room if desired. The print
report can be printed from any printer connected to the computer being used with the
VetGard.
Power is supplied by three AA alkaline batteries and these batteries will last for over 50
hours of continuous use. Battery life increases markedly by substituting long-life type AA
batteries. Rechargeable AA batteries may also be used however a charger is not available
through Vmed. Refer to the maintenance instructions at back of this manual for battery
changing instructions.

Sweep and Scale
Sweep: Sweep moves across the display left to right at the selected sweep speed. Default
sweep speed is 50 mm/sec. Sweep is magenta if sensors are off or not properly attached to
the patient. ECG sweep is green with good electrode-patient contact; Spo2 is blue with good
sensor placement; and respiration is yellow if the ECG electrodes is detecting respiration.
Vertical Scale:
The vertical scale on the display and print report measures signal
amplitude. The default gain setting is 1 for all animal species. With the gain set at 1, the
signal amplitude of 1 mV has a vertical scale deflection of 10 mm by convention. Vertical
scale deflection increases by a multiple of the gain. The amplitude of the square gain reference
marker will change with gain setting so that the signal amplitude can always be referenced to a
gain of 1.

When connection is complete, the sweep appears on the display as a flat magenta
colored line moving left to right at the selected sweep speed. Upon acquisition of a
satisfactory signal, the waveform will appear and the trace will change to a color
corresponding to each sensor:
Green: ECG
Blue: Sp02
Yellow: Respiration
White: (digits only): Temperature
Using Chest Probe
1. Place the patient in the right lateral recumbent position and pull the front legs cranial.
2. Liberally apply alcohol or electrolyte solution to the left lateral chest wall where the
electrodes will make contact. Position the chest probe over the heart, cable toward the
right shoulder, and press firmly enough that all three electrodes make good contact
with the body wall.
NOTE: A magenta ECG sweep represents a leads off condition and may occur
even if a waveform is present, however, the computer will not recognize a valid
ECG and the digital heart rate display will not appear. You should, in this case,
reposition the sensor or clip leads until a green sweep appears.
Taking the ECG
Important comments on ECG:
The VetGard obtains two types of clinical ECG information (1) rate and rhythm and (2)
QRS and P characteristics. For surgical and long term monitoring, rate and rhythm only
is needed to monitor patient status since changes in heart rate or significant variation of
the periodic interval of the beating heart may be indications of patient compromise.
Accurate Rate and rhythm can be obtained by any of the available ECG sensors provided
with the VetGard, leg clips and the internal positioned esophageal probe being the most
often used in surgery. For long term patient monitoring, leg clips or disposable chest
electrodes should be used.
Accurate diagnostic lead II ECG, on the other hand, requires information on both the
rate and rhythm of the heart and evaluation of the ECG complexes themselves.
Conductive abnormalities, for example are manifested by higher than normal R and S
amplitude. For routine ECG and pre-surgical screening, the chest sensor is most
convenient and is recommended for this application, however the method may produce
inaccuracies in amplitude if the chest probe is not positioned at the correct angle to the
heart. For this reason, whenever a beat characteristic or signal amplitude seems abnormal
when using the chest sensor, a follow up trace should be taken using the leg clips to
confirm the reading.
Note: The VetGard is packaged with a small bottle of saline electrolyte. Alcohol is
the best contact medium for animal ECG, so you might want to refill the bottle with
alcohol if the electrolyte does not give you good results.
46
Figure 4 Correct position of the chest probe for ECG exams.
3. Rotate the probe until the “R” amplitude is at its highest and a good tracing appears on
the screen. If a good tracing is not obtained, re-saturate the chest wall with more
electrolyte and reposition the chest probe. In some cases excess hair should be clipped.
NOTE: Orientation of the chest probe is important to achieve good lead II
information. Confirm all suspect “R” wave signals with the leg clips.
4. Record the ECG until three good lines of tracing are obtained. NOTE: The three
panels stacked vertically on the display represent a continuous trace with the
earliest information being replaced by the current sweep. At the default chart
speed of 50 mm/sec, the three panels represent 12 seconds of data.
5. Depress the Start/Stop button on the chest probe or on the VetGard keypad to stop
the trace. Depress the Print button on the keypad to print this display and save it to
the Reviewer. You may also print directly from the moving trace by pressing the
PRINT switch on the keypad.
47
Using Leg Clips
The three lead clips are color coded according to American Heart Association (AHA) standards.
The following table provides the list of AHA color codes for Lead II connections modified to
identify animal legs. See the table on the next page.

Plug the clip lead cable into the PC-Vet receptacle
Place animal in the right lateral recumbent or standing position
Saturate the area where clips attach with alcohol or electrolyte
Connect leg clips to the appropriate limb. Connect two clips to the hind legs, Red to
left hind and Green to right hind, on the posterior aspect of the stifle just proximal to
or distal to the point of the elbow. Connect the remaining clip, White to the right front
leg on the anterior aspect of the leg just proximal to or distal to the elbow.
Using Esophageal Probe
Vmed esophageal probes have sensors for monitoring ECG and temperature. Choose the
right probe for the size animal. If the baseline tends to wonder or deviate from a straight
line, the electrode spacing is too large and a probe with a shorter spacing should be used.
If the ECG signal is intermittent, usually with respiration, the electrode diameter is too
small for the animal and a probe with larger diameter electrodes should be used.
NOTE: Do not try to evaluate ECG traces using the esophageal probe. Sweep is
accurate for rate and rhythm only.
CAUTION: Do not use the rectal temperature probe while monitoring with
esophageal probe as inaccurate temperatures will be displayed.
1. Lay the probe on the animal simulating it being in the esophagus.
2. Place end of probe one finger width from the last rib.
3. Note the distance marked on the probe in cm at the nose.
4. Slide the probe into the esophagus until the distance marked at the animal’s nose is
at the mouth.
5. Move probe cranial and caudal until the best ECG signal is obtained.
Using Disposable Chest Electrodes
NOTE: The clip leads provided with the VetGard connect to the metal tabs on
disposable pre-gelled electrodes. Use 3M 2258-3 infant, long-term monitoring
electrodes for small animals; 3M 2270 for large animals. Disposable chest electrodes
are best for long term monitoring when the animal is under or recovering from
anesthesia. It may be necessary to shave excess hair and to place a protective
bandage around the animal covering the electrodes so they are not dislodged or
chewed off by the patient. Clip leads connect to the metal tabs.
1. Plug the three clip leads into the corresponding colored receptacle on the yoke cable.
2. Connect a clip to each of three electrodes.
3. Prepare the electrode site by clipping excess hair.
4. Wet area with alcohol and wipe dry.
5. Remove the liner from three electrodes and on each leg indicated by the color code on
the cable, preferably above the hock and elbow. Electrodes may also be placed on the
chest, over the heart and oriented to the Lead II axis.: White on the right chest toward
the right front leg, Red in the middle and Green on the left chest toward the left hind
leg. NOTE: A protective bandage should be applied over the electrodes to
prevent the animal from dislodging or chewing off the electrode or lead. Lead
II information is most accurate when electrodes are attached to the patien’s legs.
6. Smooth down the electrodes with a circular motion. Avoid pressing on center of
electrode.
48
49
™ Slide one of the sensors alignment buttons along the clip slot until the sensor is fully
engaged in the clip. (B)
Using the Rectal Temperature Probe
Plug the rectal probe into the receptacle at the front of the VetGard. Insert the tip into the
rectum to a safe depth. Wrap the Velcro strap around the base of the tail to stabilize and
secure the rectal probe. CAUTION: Do not use with esophageal probe inserted or
inaccurate temperatures will be displayed.
Using the Oxygen Saturation (Sp02) Sensor
™ Slide the second sensor button along the slot in the other side of the clip until fully
engaged as in step 3. (C) NOTE: Be sure the optical components face each other.
The sensor is now ready to be applied to the animal. The preferred application site for
canine, feline and equine patients is on the tongue with the sensor positioned at the center
of the tongue as shown (D). Alternatively, the sensor may be applied to the animals lip,
toe, ear, prepuce or vulva.
™ Failure to apply sensor properly may cause incorrect measurements.
™ Exposure of bright light at the point of sensor attachment may cause inaccurate
measurements. Cover sensor with an opaque material to block ambient light.
™ Move sensor to a new site at least every four hours. It may be necessary to move the
sensor more often with some patients.
™ Do not use supplemental tape or straps to secure sensor to the site since this may
restrict blood flow and cause inaccurate readings.
™ Use of Intravascular dyes may cause inaccurate measurements.
™ Motion, particularly repetitive motion, may compromise performance. If readings
cannot be obtained, change the site.
™ Carefully route all monitoring cables to reduce the possibility of entanglement or
strangulation.
™ Do not use during MRI scanning.
™ Do not alter or modify the sensor in any way since accuracy will be affected.
™ Do not use any other brands of Sp02 sensor with the VetGard.
NOTE: Each Sp02 reusable sensor comes with two clips that are used to apply the
sensor to different sized animals and to different sites. The sensor and clips are
indicated for use when continuous non-invasive monitoring of arterial oxygen
saturation is desired for canine, feline and equine animals. Reusable sensors may
be used on the same site for a maximum of 4 hours provided that the site is
inspected routinely to ensure skin integrity and correct positioning. Some patients
may require moving the sensor more often.
™ Clean the sensor and clip separately before and after each use (Refer to cleaning
instructions).
NOTE: If the sensor does not track the pulse reliably, it may be incorrectly
positioned-or the sensor site may be too thick, thin, or deeply pigmented to
permit appropriate light transmission. If any of these situations occur, reposition
the sensor or try another sensor site. If the sensor site is covered with furor or
hair, try shaving the site and reapplying the sensor.
1. Attach the sensor as described above. Ensure that the sensor cable is positioned along
the side of the animal’s face and body to avoid entanglement with the animal. (E)
2. Plug the sensor connector into the receptacle on the VetGard and verify proper
operation.
NOTE: To verify correct placement of the sensor on the site, manually take a
pulse rate reading at another site on the animal. If the sensor is placed
correctly, the manual reading should correspond to the pulse rate reading
displayed on the VetGard computer screen.
CAUTION : For the comfort of the animal and to avoid damaging the sensor, do
not pull on the cable when removing the sensor and clip from the sensor site.
3. To remove the sensor and clip from the animal, press the clip open and remove.
4. To remove the sensor from the clip, grasp the end of each sensor pad and pull it through
to the inside of the clip. The sensor should pop out of the clip easily. Do not pull on the
cable.
™ Open the clip by pressing with the thumb and forefinger as shown (A)
