Reporting; Central Sleep Apnea Detection; Cheyne-Stokes Respiration Detection - ResMed AirSense 10 AutoSet for Her Plus Clinical Manual

Reporting

The AirSense 10 detects Central Sleep Apnea (CSA) and Cheyne-Stokes Respiration (CSR). The
Summary and Detailed Data of these parameters are available to view on ResMed patient
compliance software (data availability depends on device mode and parameter measured).

Central sleep apnea detection

Available in all modes on the AirSense 10 AutoSet Plus, AirSense 10 AutoSet for Her Plus and the
AirSense 10 Elite Plus.
The device detects both obstructive and central sleep apneas (CSA). CSA detection uses the Forced
Oscillation Technique (FOT) to determine the state of the patient's airway during an apnea. When an
apnea has been detected, small oscillations in pressure [1 cm H O (1 hPa) peak-to-peak at 4 Hz] are
2
added to the current device pressure. The CSA detection algorithm uses the resulting flow and
pressure (determined at the mask) to measure the airway patency.

Cheyne-Stokes respiration detection

Available in all modes on the AirSense 10 AutoSet Plus, AirSense 10 AutoSet for Her Plus and the
AirSense 10 Elite Plus.
Cheyne-Stokes respiration (CSR) is a form of sleep-disordered breathing characterized by a periodic
waxing and waning of respiration. The waxing periods (hyperpneas, typically 40 seconds in length)
can include large gasping breaths that tend to arouse the patient while the waning periods
(hypopneas or apneas, typically 20 seconds in length) cause blood oxygen desaturations.
The following example shows a typical CSR period.
