Abstract

Method and device for determining an incident of a sleep related respiratory event, from ECG data and oximetry data are disclosed. The method comprises determining occurrence of an attenuation in ECG derived respiratory signal below a first threshold, determining occurrence of a desaturation in the oximetry data below a second threshold, determining occurrence of an attenuation in ECG derived respiratory signal below a third threshold with a corresponding desaturation in the oximetry data below a forth threshold, determining occurrence of an attenuation in ECG derived respiratory signal below a fifth threshold with a corresponding detection of arousal; and determining the incident of a sleep related respiratory event if any of the occurrences exists.
