Pressure Control Ventilation Therapy Modes
Pressure Control ventilation modes deliver a prescribed pressure to
the patient.
Continuous Positive Airway Pressure (CPAP) Mode
In the Continuous Positive Airway Pressure (CPAP) mode, the device
delivers a continuous pressure to the patient at all times. All breaths
in this mode are Spontaneous breaths.
Spontaneous (S) Mode
In Spontaneous (S) mode, the device delivers bi-level pressure
support. This mode provides only spontaneous breaths. In this
mode, an Inspiratory Positive Airway Pressure (IPAP) is delivered
during inhalation and a lower Expiratory Positive Airway Pressure
(EPAP) is delivered during exhalation. The following illustration
describes these concepts.
