Abstract: A positive airway pressure (PAP) device including an air pump for blowing air into a mask worn by a user, a sensor for detecting air pressure or air flow-rate produced by the air pump, a communication interface for communicating with a physiological parameter sensor worn by the user for detecting a physiological parameter of the user, and a processor. The processor is configured to control the air pump to blow the air into the mask according to the air pressure or air flow-rate sensed by the sensor to achieve a prescribed air pressure or air flow-rate, and control the air pump to adjust the prescribed air pressure or air flow-rate in response to the detected physiological parameter.

Abstract: A portable smart device including a coupled sensor sensing a physiological parameter of a user, and a processor. The processor is configured to perform a breath training session by instructing the user to breath in a specified manner, receiving physiological data from the sensor, the physiological data representing the sensed physiological parameter of a user, determining a breathing quality based on the physiological data from the sensor, and stopping the breath training when the breathing quality reaches a breath training session stopping threshold. The processor is further configured to evaluate initiation of a further breath training session by receiving the physiological data from the sensor while the user is sleeping, and repeating the breath training session in response to the physiological data from the sensor indicating that the breathing quality reaches a breath training session starting threshold.

Abstract: A system and method for diagnosing and treating sleep disorders using a portable smart device. The device detects and records physiological parameters of a user during awake and sleep states. A processor analyzes these parameters to determine at least one of a loop gain or an arousal index of the user's ventilatory control system. A trigger mechanism initiates a disturbance of the ventilatory control system during awake and sleep states and monitors the response of the ventilatory control system to such disturbance. The system can provide feedback to the user based on at least one of the determined loop gain or the arousal index and display these parameters to the user via a user interface.
