Volume controlled regulated pressure
Description:
Time cycled ventilation mode and limited
pressure using tidal volume as feedback to
continuously
adjust
the
pressure
threshold.
The first three breaths are in volume
control mode, allowing the ventilator to
calculate respiratory mechanics. In the
next cycle ventilation is distributed with
pressure limit and cycled time to reach
60% of the set volume.
At each cycle the ventilator adjusts the
pressure limit (5 cmH2O upward) as the
tidal volume delivered in the previous
cycle, until reaching the tidal volume
specified by the operator.
The maximum pressure limit is 5 cm H2O
below the pressure limit indicated by the
operator.

Whenever the apnea set time is reached, the ventilator
triggers a ventilatory cycle whose configuration is based on the
current mode settings.
As soon as all ventilation parameters are adjusted on the ventilator, the same calculates T
EXP
according to the Rate and T
INS
; thus, obtaining all ventilation control times.
