| CPAP: provides a constant level of pressure throughout the breathing cycle.

S: a Bi-Level mode that responds to both inhalation and exhalation. The pressure increases as the user inhales and decreases as the user exhales. There is no inspiratory pressure if user does not inhale. IPAP (Inspiratory Positive Airway Pressure) and EPAP (Expiratory Positive Airway Pressure) are pre-determined by user’s healthcare provider.

T: a Bi-Level mode that the device controls the timing of inhalation and exhalation according to the preset parameter.

S/T: a Bi-Level mode that responds to both inhalation and exhalation. The pressure increases as the user inhales and decreases as the user exhales. If no inhalation is detected within a set time, the device automatically starts inhalation. When the device starts inhalation, it controls the time of inhalation and automatically decreases the pressure for exhalation within a set time.

APCV: a Bi-Level mode based on the S/T – the device controls the time of inhalation and automatically decreases the pressure for
