DISCRIMINATION OF CHEYNE -STOKES BREATHING PATTERNS BY USE OF OXIMETRY SIGNALS

摘要

A computer implemented method and apparatus for detecting the occurrence of Cheyne-Stokes breathing are disclosed. An apparatus comprises a memory for blood gas data representing a measured blood gas signal and a processor coupled with the memory. The processor is configured (a) to determine a duration of one or more contiguous periods of changing saturation of a blood gas from the blood gas data and (b) to detect an occurrence of Cheyne-Stokes respiration from a comparison of the determined duration and a threshold derived to differentiate saturation changes due to Cheyne-Stokes respiration and saturation changes due to obstructive sleep apnea.
