3.PEEP
The Positive End Expiratory Pressure (PEEP) setting can be
increased from 0 to 25 cm H2O in active circuits and 4 to 25 cm H2O 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.
