CONTINUOUS POSITIVE AIRWAY PRESSURE MODE
Definition
Continuous Positive Airway Pressure (CPAP) is a ventilation mode intended for
patients who are breathing spontaneously at a rate sufficient to meet their
ventilation requirements. During CPAP, the airway pressure remains above
ambient at all times, reducing the work of breathing.
Available Breath Types
Patient spontaneous and pressure support breaths can be delivered in this mode.
Mandatory breaths are not provided (except manual breaths).
Description
Figure 172 illustrates how breaths are delivered in this mode.
Figure 172: Pressure During CPAP Mode for Spontaneous Breaths and Pressure Support Breath
Patient triggering results in the delivery of a patient breath (spontaneous or
pressure support). The ventilator maintains airway pressure (as in Figure 172
during the inspiratory phase at PEEP level. If pressure support is selected, the
ventilator maintains an elevated support pressure (b in Figure 172 during the
inspiratory phase). Breaths can only be initiated after inspiration has ended and
the minimum exhalation time has elapsed.
PARAMETERS SETTING
The following parameters can be set:

O2%

Triggering type and sensitivity

Support pressure for pressure support breaths
