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.

	IPAP = 26 cm H2O			1	= Pressure Supported
	EPAP = 6 cm H2O				Spontaneous Breath
	PS = IPAP-EPAP = 20 cm H2O
