A method for training a classifier to discriminate Cheyne-Stokes respiration from blood oxygen saturation levels measured by an oximetry signal is disclosed comprising pre-classifying polysomnographic data to obtain non-overlapping epochs each with a specified class of dominating event with a processor, segmenting oximetry and flow recordings into non-overlapping epochs of data having a predetermined length of time and forming a decision boundary with a processor to discriminate Cheyne-Stokes respiration and non-Cheyne-Stokes respiration classes of events with the epochs.
