AHI and Total AI: Central sleep apnoea detection (CSAD) is not active in ASVAuto and ASV modes. The ASV algorithm
eliminates central apnoeas. Therefore, any apnoeas reported by the device will be obstructive or indicative of a closed
airway.
Description
Number of hours the device has been used during the last session.
Apnoeas and hypopnoeas measured per hour for one day. An apnoea is when the
respiratory flow decreases by more than 75% for at least 10 sec. A hypopnoea is when
the respiratory flow decreases to 50% for at least 10 sec. The Apnoea Index (AI) and
Apnoea-Hypopnoea Index (AHI) are calculated by dividing the total number of events
that occurred by the total mask-on therapy period in hours.
