Abstract

Disclosed is a system and method for monitoring, diagnosing, and treating certain respiratory conditions, such as asthma. The system includes a mask apparatus fitted with a pH sensor and thermocouple, a continuous positive airway pressure (CPAP) device, a processing receiver, and a therapeutic nebulizer/atomizer/humidifier device. The mask apparatus, CPAP device and therapeutic nebulizer/atomizer/humidifier device are connected by a pneumatic means. The pH sensor and the thermocouple are in electrical communication with the processing receiver that controls, through an electronic means, the CPAP device and therapeutic nebulizer/atomizer/humidifier device. The electrical communications can be in the form of a plurality of wires or employ wireless means.
