Abstract
A method and apparatus for optimizing the controlled positive pressure in treating sleep disordered breathing by using the appearance or disappearance of cardiogenic oscillation in the airway signal as an additional parameter useful for classifying the level of resistance. Ambiguities in breath monitoring can be resolved to determine whether or not breathing is labored due to an obstruction by the presence or absence of cardiogenic oscillations.
