3.2 Ventilation modes

The Elisée 350 offers seven ventilation modes:
•
•
•
•
•
•
•
(Assisted) Controlled Ventilation
In (Assisted) Controlled Ventilation, the device delivers cycles with a fixed inspiratory time and
set volume ((A)CV mode) or set pressure (P(A)CV mode).
•
•
In either of these modes, you can program recruitment cycles.
These cycles are always pressure-controlled, whether the device is in ACV or PACV mode. The
ventilator triggers breaths for the patient. The adjustable parameters are:
•
•
•
When the device is in ACV mode, you can also set a plateau time using the End-inspiratory pause
button.
(Assisted) Volume-Controlled Ventilation ((A)CV)
In (A)CV mode, cycles are flow-controlled during a fixed inspiratory time to ensure the set volume
is delivered. Controlled cycles are delivered according to the respiratory rate set by the clinician.
In ACV mode, assisted controlled cycles can be triggered by the patient over and above the set
respiratory rate.
20/102
In manual mode (%): The expiratory trigger is expressed as a percentage of the maximum
flow. The expiratory phase is triggered when the decreasing flow reaches the set flow
percentage value.
TgE = 40%
TgE = 25%
TgE = 10%
(Assisted) Volume-Controlled Ventilation ((A)CV)
(Assisted) Pressure-Controlled Ventilation (P(A)CV)
Synchronised Intermittent Mandatory Ventilation (SIMV)
Pressure-Synchronized Intermittent Mandatory Ventilation (PSIMV)
Pressure Support (PS)
Pressure Support with Minimum Tidal Volume (PS.V
Continuous Positive Airway Pressure (CPAP).
In ACV and PACV modes, breaths can be triggered by the ventilator, by the patient (through
the flow or pressure trigger) if the patient's respiratory rate is higher than the set
respiratory rate, or by the user (by pressing the Manual breath button).
If breaths are triggered by the ventilator alone, ventilation is no longer Assisted Controlled
ventilation but Controlled Ventilation (CV or PCV). On the screen, the "A" of ACV or PACV
is greyed out.
The recruitment period: the interval between two recruitment cycles, in minutes
The recruitment size (s): the duration of insufflation during the recruitment cycle
The recruitment pressure (cm H
t
t
O): the pressure insufflated during the recruitment cycle.
