Abstract

The present invention discloses a method for developing a diagnostic method for Cheyne-Stokes Respiration (CSR). The method comprises the steps of performing overnight oximetry recordings (16) in patients suspected of obstructive sleep apnea (10) who have been identified as having or not having CSR (14) by clinical studies (12). Spectral analysis (20) is performed on the oximetry recordings (16) from which a classification tree (26) is generated. The present invention also discloses a method for the identification of CSR in an individual. The method of identification comprises the step of performing spectral analysis of overnight oximetry recordings. The key features are then input into a classification tree to determine the presence or absence of CSR.
