Central sleep apnea detection (CSAD) is not active in ASV mode. The ASV algorithm eliminates central apneas,
provided the EPAP is sufficient to maintain an open airway. Therefore, any apneas reported by the device will be
obstructive or indicative of a closed airway.

Description
Displays the following information on last night's usage, mask fit and AHI
data.
Time period displayed as Last night (last session).
Number of hours the device has been used during the last session.
Indicates 'Good' if the 70th percentile leak is less than 24 L/min.
Apneas and hypopneas measured per hour for one day. An apnea is when
the respiratory flow decreases by more than 75% for at least 10 sec. A
hypopnea is when the respiratory flow decreases to 50% for at least 10
sec. The Apnea Index (AI) and Apnea Hypopnea Index (AHI) are calculated
by dividing the total number of events that occurred by the total mask-on
therapy period in hours.
Displays additional therapy settings and compliance information (eg, Days
used, Used Hrs).
Sets time periods to a day, week, month (1, 3 or 6) and year to display
available data.
This period is the only parameter you can change in the Sleep Report—other
parameters are for display only.
Number of days the device has been used during the selected period or
since the last compliance data was reset.
Number of days the device has been used for more than 4 hours during the
selected period or since the last compliance data was reset.
Average number of hours per day the device has been used during the
selected period.
Number of hours the device has been used during the selected period or
since the last compliance data reset.
Average inspiratory pressure during the selected period (95th percentile for
each day; average of the 95th percentile values for periods >1 day).
Average expiratory pressure during the selected period (95th percentile for
each day; average of the 95th percentile values for periods >1 day).
Average of the 95th percentile values of leak during the selected period for
days with usage only.
Average of the 50th percentile values of tidal volume during the selected
period for days with usage only.
Average of the 50th percentile values of respiratory rate during the selected
period for days with usage only.
Average of the 50th percentile values of minute ventilation during the
selected period for days with usage only.
Apnea-Hypopnea Index—average AHI during the selected period. AHI and AI
are calculated for times of low leak only.
Apnea Index—average total AI during the selected period.
