Continuous Positive Airway Pressure


A method of respiratory ventilation used primarily in the treatment of sleep apnea.


Components of the device:

  • Flow generator provides the airflow

  • Hose connects the flow generator (sometimes via an in-line humidifier) to the interface

  • Interface (nasal or full face mask, nasal pillows, or less commonly a lip-seal mouthpiece) provides the connection to the user's airway



Bilevel/Variable Positive Airway Pressure


Provides two levels of pressure:

  • Inspiratory Positive Airway Pressure (IPAP)

  • Lower Expiratory Positive Airway Pressure (EPAP) for easier exhalation



  • S (Spontaneous) - In spontaneous mode the device triggers IPAP when flow sensors detect spontaneous inspiratory effort and then cycles back to EPAP.

  • T (Timed) - In timed mode the IPAP/EPAP cycling is purely machine-triggered, at a set rate, typically expressed in breaths per minute (BPM).

  • S/T (Spontaneous/Timed) - Like spontaneous mode, the device triggers to IPAP on patient inspiratory effort
