Receiving a diagnosis of sleep apnea can be overwhelming, especially when it comes to understanding the terminology surrounding CPAP (Continuous Positive Airway Pressure) therapy. At Advanced Respiratory Care Network, we're here to help you navigate the world of CPAP and sleep apnea. So, let’s define and explain common CPAP terminology for those who are new to sleep apnea diagnosis.
CPAP Terminology: A to Z
AHI (Apnea-Hypopnea Index)
AHI is a measure of the severity of sleep apnea. It's calculated by adding the number of apneas (breathing pauses) and hypopneas (shallow breaths) that occur per hour of sleep.
APAP (Auto-CPAP)
APAP is a type of CPAP machine that automatically adjusts the air pressure based on the user's needs.
Bi-Level (BiPAP)
Bi-Level is a type of CPAP machine that delivers two different pressure settings: one for inhalation and one for exhalation.
CPAP (Continuous Positive Airway Pressure)
CPAP is a therapy that uses a machine to deliver a constant flow of air pressure into the airways to keep them open during sleep. Browse our full selection of CPAP and BiPAP therapy machines!
Diffuser
Small accessory that attaches to your CPAP mask or hose. Its primary function is to reduce noise and disperse the air more gently. Shop now and other accessories!
Exhalation Pressure (EPAP)
EPAP is the pressure setting on a Bi-Level machine that is used during exhalation.
Humidifier
A humidifier is a device that adds moisture to the air delivered by the CPAP machine to reduce dryness and discomfort.
Inhalation Pressure (IPAP)
IPAP is the pressure setting on a Bi-Level machine that is used during inhalation.
Leak Rate
The leak rate indicates how much air is escaping from the mask. A high leak rate can affect the effectiveness of your therapy and should be addressed.

- Nasal Pillow Mask: A nasal pillow is a type of mask that fits into the nostrils to deliver air pressure, offering a minimalistic design.
- Full Face Mask: Covers both the nose and mouth, suitable for mouth breathers or those with nasal congestion. Check out all the full face masks we carry!
Pressure Setting
The pressure setting is the level of air pressure delivered by the CPAP machine, measured in centimeters of water (cmH2O).
Ramp Feature
The ramp feature is a setting on some CPAP machines that allows the user to gradually increase the air pressure over a set period of time.
Sleep Apnea
Sleep apnea is a sleep disorder characterized by repeated pauses in breathing during sleep.
Snore Detection
Snore detection is a feature on some CPAP machines that detects and records snoring events during sleep.
Titration Study
A titration study is a sleep study that determines the optimal CPAP pressure setting for an individual.
Xyrem
Xyrem is a medication used to treat cataplexy and excessive daytime sleepiness in people with narcolepsy.
