Abstract
A system for detecting and identifying sleep apnea, such as obstructive sleep apnea, that includes a non-contact patient monitoring system and a pulse oximetry system. The methods utilize respiratory parameters (e.g., respiration rate, respiration volume) from the non-contact patient monitoring system to determine a significant reduction in or absence of the patient's respiration. The methods also utilize cardiological information (e.g., pulse) from a pulse oximetry system to determine intrathoracic pressure increases from various modulations of the PPG signal during the patient's respiration cycle.
