3. PEEP
The Positive End Expiratory Pressure (PEEP) setting can be
increased from 0 to 25 cmH
2
O in active circuits and 4 to 25
cmH
2
O in passive circuits, in increments of 1. PEEP is the positive
pressure maintained in the patient circuit during exhalation. The
PEEP must be less than or equal to the pressure setting.
Control Ventilation (CV) Mode
The following settings, described in the previous sections of this
chapter, are also available in CV mode:
Tidal Volume
•
Breath Rate
•
Inspiratory Time
•
PEEP
•
High Inspiratory Pressure
•
Low Inspiratory Pressure
•
In addition to these, the following settings are also available in CV
mode.
1. Flow Pattern
You can choose either Ramp or Square for the Flow Pattern setting.
2. Sigh
You can enable or disable the Sigh setting by selecting On or Off.
A Sigh is a breath that is delivered every 100 breaths at 150% of
the normal volume.
Note:
The Flow Pattern setting
might be limited to only Ramp
or Square based on the Tidal
Volume, Inspiratory Time, and
Breath Rate settings to maintain
the minimum and maximum
peak flows.
Note:
The Low Inspiratory
Pressure is limited to PEEP +2 in
CV, AC, and SIMV modes.
