A notification system monitors changes in air flow channeled between a positive air pressure generator and a CPAP mask supplying positive airway pressure to a patient during treatment of sleep apnea. An air flow sensor and/or pressure sensor is positioned to monitor air flow channeled to the mask. When a sensor detects a significant change in air flow and/or air pressure, a detection signal is analyzed by a controller unit microprocessor for comparisons with a preselected operating range for air flow and/or pressure. Upon verification the air flow and/or pressure is not within the preselected range, a remote transmission is transmitted to an alarm means proximal of the patient. The alarm means directs at least one stimulus to the patient for alerting and waking the patient. The alarm stimulus includes audio and/or vibratory stimuli of sufficient intensity to alert the patient that mask adjustments are required for proper CPAP treatment.

Having thus described the aforementioned invention, I claim: 1. A system for monitoring and regulating air flow to a patient adapted to supply positive airway pressure to a patient mask during treatment of a sleep disorder, comprising: a CPAP generator for providing variable airway pressure; a first sensor for monitoring air flow channeled to the patient from said CPAP generator for generating first and second air flow rate detection signals representing the airflow to the mask and from the mask, respectively; a second sensor for measuring pressure in the air flow, said second sensor detecting a change in pressure at a selected place in said system, said second sensor generating a pressure detection signal upon detection of the change in pressure; a controller unit responsive to said first and second air flow rate detection signals said controller unit having means for interpreting, storing and comparing said first and second air flow and pressure detection signals and providing an outgoing alarm signal when the first air flow signal increases, the second air flow signal decreases and the pressure detection signal decreases; a remotely-controlled transmitter means in communication with said controller unit, said transmitter means generating a transmitter alarm signal in response to said outgoing alarm signal from said controller unit; and alarm generation means selected from the group consisting of a vibration device releasably disposed on the patient's torso, a vibration device releasably attached on the patient's extremity, an audio device movably located proximal to the patient, and a an audio device removably attachable to the patient's head. 2. The notification system of claim 1 wherein said transmitter means includes a radio frequency transmitter for transmission of said alarm signal over a sufficient distance for receipt by said alarm means having a radio frequency receiver therein. 3. The notification system of claim 1 further comprising a timing circuit in electrical communication with said controller unit microprocessor, said timing circuit provides control of a frequency of repetitive analyses accomplished by said microprocessor means for comparing, thereby providing control of the frequency of generation of said alert signal generated by said controller unit. 4. The notification system of claim 1 wherein said sensors are calibrated for detection of air pressure greater than said preselected range of air pressure. 5. The notification system of claim 1 wherein said sensor is calibrated for detection of air pressure lower than said preselected range of air pressure. 6. The system of claim 1 further including a humidifier. 7. The system of claim 1 further comprising a timing circuit in electrical communication with said controller and responsive to selection means used by the patient to indicate a hibernation mode whereby said controller disables the alarm.
