SmartCare/PS in a nutshell
Option for Evita V500/Evita V300 SW. 2.n
 The SmartCare/PS system is an automated clinical
protocol, designed to
– stabilize the patient's spontaneous breathing in a
comfortable zone of normal ventilation and
– to automatically reduce the inspiratory support
– to perform an automatic spontaneous breathing trial
 SmartCare/PS can be used for weaning intubated or tracheotomised patients with a
body weight above 15 kg.
 The patients should be ready for weaning, i.e., haemodynamically stable with
adequate oxygenation and spontaneous breathing.

– The decision to wean was made.
– The decision to wean in SPN-CPAP/PS was made.
– The decision to wean automatically through SmartCare/PS was made.
– The treating physician and/or person responsible for the treatment has deemed the patient to be
hemodynamically stable.
– The patient's spontaneous respiratory rate is stable.
– The patient does not suffer from a severe chronic obstructive pulmonary disease (COPD).
– The patient does not suffer from any major neurologic disorders that influence the respiratory
center.

can adapt to the medical history of
the patient
 Set neurological disorder to “Yes”
when treating patients with slightly
increased breathing frequency up
to 34 bpm due to neurological
disorders

Set SmartCare/PS
Step 4: Night rest
 Touch the screen key »Night rest«
 When »Night rest« is activated,
SmartCare/PS will not actively
reduce the PS for weaning
purposes during the set period of
time
 Nevertheless, even during night rest
the SmartCare/PS protocol will
keep the patient stable, i.e. react
accordingly to any of the 8
diagnoses
 The time period can be modified at
any time, including during night rest

Typical sequence of a patient session
 SmartCare/PS
first attempts to stabilize the patient's spontaneous breathing by
adjusting the pressure support
 “Adapt”: Pressure support is regularly adapted to the patient's respiratory profile
 “Observe”: When pressure support reaches a minimum value SmartCare/PS starts a
spontaneous breathing trial (SBT)
 “Maintain”: When the SBT concluded successfully, the system displays a
recommendation to disconnect the patient from Evita V500 and continues to keep
the patient stable

FAQ
 Is SmartCare/PS failsafe, because it
alters the pressure on its own?
– SmartCare/PS is an independent
add-on to Evita V500/V300 and
does not alter the safety
mechanisms built into the
ventilator. All alarm limits reactions
based on the severity of alarms
remain untouched.
– Therefore, we recommend setting
the following alarm limits before
starting a patient session:
Parameter
Alarm limit
MV low
–25 % of current MV
MV high
25 % of current MV
RRspon high
40/min with body weight ≥ 36 kg
60/min with body weight ≤ 35 kg
VT low
4 mL/kg body weight
VT high
12 mL/kg body weight
Paw
42 mbar with body weight ≥ 36 kg
etCO2 low
29 mbar with body weight ≤ 35 kg
etCO2 high
18 mmHg
etCO2 high
57 mmHg (without COPD)
67 mmHg (with COPD)
38 | 46
FAQ
 What if my patient goes apneic?
– The Evita V500 ventilator’s apnea
ventilation will kick in as backup ventilation
in case of an apnea episode with the tidal
volume and frequency you have set.
– In this case the caregiver is notified and the
patient session is ended.
39 | 46
FAQ
 Can I use any humidifier?
– For patients with body weights >35 kg, any
active humidifier or passive heat-moistureexchanger (HME) can be used
– For patients with body weights <= 35 kg,
only active humidification can be used
40 | 46
FAQ
 Can I use SmartCare/PS at night to keep the
patient stable, but not to wean?
– SmartCare/PS comes with the function
“Night rest”
– You can set a time period during which the
patient will be kept stable by the system in
the comfortable zone of normal ventilation,
but with no weaning off the ventilatory
support
– If necessary, the system will increase the
Pressure Support during night rest
– Weaning will automatically commence after
the night rest period has ended
41 | 46
FAQ
 What if SmartCare/PS recommends
“SC: SBT successful”, but no decision maker
is available?
– SmartCare/PS will enter the „Maintain”
phase and keep the patient ventilated on
the lowest level of Pressure Support
– Should the patient develop instabilities or
require higher levels of support pressure
SmartCare/PS will stabilize the patient
according to the protocol
– Should instabilities persist, SmartCare/PS
will switch back to the “Adapt” phase
42 | 46
FAQ
 Is SmartCare/PS affected by the usage of
nebulized drugs?
– As long as the etCO2 and flow sensors are
not rendered inoperable by excessive
amounts of nebulized drugs, SmartCare/PS
is not affected.
43 | 46
FAQ
 What happens during bronchial suctioning?
– Endotracheal suctioning can be performed
as often as necessary without having to
activate any special procedure.
– However, it is highly recommended that the
suction function of Evita V500 will be used
with pre- and post-oxygenation.
– This allows SmartCare/PS to detect
reactions to suctioning, so that respiratory
changes are not considered as instabilities
with subsequent actions based on the
protocol.
44 | 46
FAQ
 Can I change the Pressure Support level
during a SmartCare/PS patient session?
– Yes
– The Pressure Support level can be altered
manually at any time
– SmartCare/PS will continue with the current
phase with the new Pressure Support level
