21/102 Ventilation
NOT013281-8
Cycling occurs at the end of the inspiratory time (Ti) set by the user. For volume modes only, Ti
is set either directly by means of the Ti setting, or indirectly by means of the I:E or max settings,
see “Selecting target parameters in ACV mode (during ventilation and while ventilation is
stopped)” on page 63.
The adjustable parameters are as follows:
Note:
In (A)CV mode, the Elisée 350 delivers flow-controlled breaths. The airway pressure and
the alveolar pressure depend on the resistance and compliance of the patient’s respiratory
system.
WARNING
To avoid the risk of barotrauma, it is important to set the High Pressure alarm (Pmax) and
to monitor the measured values, in particular the plateau pressure if a plateau time was set.
(Assisted) Pressure-Controlled Ventilation (P(A)CV)
In P(A)CV mode, cycles are pressure-controlled. The flow is adjusted so that the set pressure is
maintained during a set inspiratory time.
The target Pi is added to the PEEP, so Total inspiratory pressure = Pi + PEEP. Controlled cycles
are delivered according to the respiratory rate set by the user. In PACV mode, assisted controlled
cycles can be triggered by the patient over and above the set respiratory rate.
The tidal volume and the minute volume are based on the resistance and compliance of the
patient’s respiratory system.
