SYSTEMS AND METHODS FOR DISTINGUISHING BETWEEN CENTRAL APNEA AND OBSTRUCTIVE APNEA

A patient monitoring system may acquire a time series of oxygen saturation data based on a physiological signal. A potential apneic event may be detected in the time series of oxygen saturation data in the form of a desaturation followed by a resaturation defined by a fall peak, nadir, and rise peak crossing respective thresholds. The potential apneic event may be qualified using a plurality of metrics derived from a portion of the time series of oxygen saturation data that corresponds to the potential apneic event. The qualified apneic event may be classified as being due to one of central apnea and obstructive apnea based on the output of a classification neural network the inputs to which comprise at least a second plurality of metrics.
