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
BIPAP / VPAP
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
