O/mbar above PEEP/CPAP
and the pressure limit setting in order to try to achieve the set tidal volume. The set tidal volume is
not guaranteed for each breath; it is a target.
The target pressure of the first breath, when no target pressure has been established, is PEEP/
CPAP+5 cmH
2
O/mbar.
Volume Target Pressure Support (VTPS)* breaths are cycled off when one of three thresholds is
attained: delivered flow declines to a set percent (%) of peak flow (user set via expiratory threshold
in
Advanced
data set), the duration of the breath reaches the maximum inspiratory time (2.0
seconds for adult, 1.2 seconds for ped/infant) or pressure overshoot, whichever comes first.
Reference
for an illustration of pressure overshoot.
Take care to set the expiratory threshold so that the breath cycling off coincides with the end of
patient effort or choose AUTO to allow FlexCycle to adjust the expiratory threshold setting breath
by breath.

Ventilation Modes
Breath types include the choice of three modes:
•
Assist/Control Mandatory Ventilation (A/CMV)
•
Synchronized Intermittent Mandatory Ventilation (SIMV)
•
Spontaneous (SPONT)
A.4.1
A/CMV
Figure A-4.
A/CMV
In A/CMV, all breaths delivered to the patient are delivered according to the parameters set by the
user. These are called mandatory breaths. The user may choose to Pressure Control, Volume Control,
Biphasic Pressure Release,* or Volume Target Pressure Control* the mandatory breaths. All breaths
may be time (ventilator triggered) or patient triggered.
