ABSTRACT:
A respiratory monitoring apparatus that detects changes in physiological parameters relevant to respiration, including blood oxygen and blood volume, using near infrared spectroscopy. Methods for diagnosing respiratory-related events including hypoxia index, hypopnea, arousal, tissue oxygen debt, and respiratory muscle events or distinguishing central from obstructive sleep apnea are also disclosed.
