Abstract

The breathing disorder treatment system is a continuous monitoring and an actuated stimulation system for the treatment of breathing disorders, such as sleep apnea. The system includes computer readable memory in communication with a processor, and a threshold blood oxygen saturation (BOS) level is recorded therein. A BOS sensor is provided for continually measuring the blood oxygen saturation level in the patient. The BOS sensor is in communication with the processor, such that the measured BOS level is continually compared with the threshold BOS level. A timer is in to communication with the processor, so that if a series of measured BOS levels are less than or equal to the threshold BOS level, a time of apnea or low BOS occurrence is recorded in the memory, and an alarm is actuated according to a calculated moving average period based upon the times of occurrence.

recording a time of low blood oxygen saturation occurrence in computer readable memory when the measured blood oxygen saturation is less than or equal to the threshold blood oxygen saturation level;

calculating a time period between sequential times of low blood oxygen saturation occurrence; and

generating an alarm signal to actuate an alarm at regular intervals based upon the calculated time period to raise the patient'"'"'s level of consciousness.

2. The method of treating a breathing disorder as recited in claim 1, further comprising the step of generating the alarm signal when the measured blood oxygen saturation is less than or equal to the threshold blood oxygen saturation level.

3. The method of treating a breathing disorder as recited in claim 2, further comprising the step of establishing a period of time of deactivation of the alarm signal.
