7.4.2 APCV

APCV is a pressure controlled ventilation, synchronised with the patient's breathing.
With this parameters configuration, APCV is a pressure controlled ventilation,
synchronised with the patient's breathing, during which the system generates a
ventilates the patient at a pre-set inspiratory pressure (PLIM), a pre-set flow (Flow),
a calculated I:E ratio and a settable respiratory rate (RR).
In APCV the current volume depends on the limit pressure (PLIM) and on the
patient's lungs characteristics (compliance, lung capacity) therefore the tidal volume
will vary depending on changes in lung mechanics.
During the inspiratory phase, the ventilator generates a settable flow (Flow). When
the airway pressure reaches the control value (PLIM), this pressure level is kept
constant by the ventilator until the end of the inspiration that you can set using (RR)
and a I:E ratio.
Use the settable parameters to define an inspiratory trigger (Trig. I) used to set a
flow expressed in litres per minute (or a pressure in cmH 2 O) that represents the limit
for detecting the patient's spontaneous breathing attempt. The greater the value, the
greater the patient's effort to breath.
If the pressure set is not reached, make sure that the patient circuit is perfectly
sealed and that the PRP parameters are properly set.
