pressure supplied during a sigh (unit x PI; e.g.: PI sigh = 1.4 PI)
Sigh sigh periodicity (1 sigh every x cycles)
Note: The PI value corresponds to the total inspiratory pressure applied to the patient. The
PEEP value is incorporated in the PI.
In (A)PCV mode, unlike (A)VCV, the pressure delivered to the patient is controlled but the tidal and
minute volumes are not.
4.6.4 PSV (spontaneous ventilation with inspiratory assistance and PEEP)
[PSV = Pressure Support Ventilation]
Principle
A constant positive pressure is maintained above PEEP level in the patient circuit for each inspiratory
effort.
The switch to the expiratory phase can be triggered:
•
If the flow rate falls below the set expiratory threshold (Trig. E);
• By an expiratory effort from the patient,
• If the maximum set insufflation time is reached (TImax).
If there is no inspiratory effort, the ventilator provides the minimum set frequency.

Note: Apnea ventilation can be activated; the apnea parameters should be suited to the con-
dition and requirements of the patient.
