CAUTION
Ensure Pmax is set to a conservative setting in this
mode initially to ensure the volume setting does
not cause barotrauma in the patient.
Always check unit operation with a bag/test lung
before connecting to the patient to ensure correct
settings have been made and the unit is delivering
as prescribed.
NOTE
It is recommended that the I: E mode be set to
“Manual” mode when tidal volumes lower than
300 ml are targeted. The user can then manually
set the Inspiration Time (“Timer Insp”) to a suitably
higher value than that when the tidal volume is not
achieved.

Pressure Controlled Ventilation (PCV)
Pressure controlled ventilation is a mode of ventilation in which the pressure is the set point. The pressure is achieved during the
Inspiration phase in a time determined by the flow control. The pressure is then maintained for the duration of the inspiration
time and then released against the PEEP valve. Setting high ramp speeds will get the system up to pressure quickly but will cause
higher peak pressures to be achieved before the unit controls back to the set plateau pressure. Lower flow settings will achieve a
lower peak pressure but may not allow the system to achieve the set plateau pressure in the Ti set on the RR. If the plateau
pressure is not achieved the unit will alarm
with a “pressure not achieved increase
flow rate
” flag.
When in Volume Controlled Ventilation mode, the “PRESSURE CONTROL” page displays as follows:
