Abstract
A system for automatically detecting and indicating the presence of clinically significant airway instability comprises a patient monitor such as a pulse oximeter for generating a time series of oxygen saturation values and a processor programmed to convert the time series to at least one set of frequency components to detect the occurrence of clustered variations indicative of instability of the airway by identifying an indicative pattern of said frequency components. The system is further programmed to provide an automatic output in response to the detection of said occurrence.
