System And Method For Diagnosing Sleep Apnea Based On Results Of Multiple Approaches To Sleep Apnea Identification
First Claim
1. A method of determining the physiological status of a patient, comprising:
- monitoring the patient with at least one sensor to produce physiological parameter data comprising a sequence indicative of blood oxygen saturation over a time period;
analyzing the physiological parameter data with a first pattern recognition feature to identify indications of sleep apnea;
calculating a first sleep apnea metric with the first pattern recognition feature based on indications of sleep apnea identified by the first pattern recognition feature in the physiological parameter data;
analyzing the physiological parameter data with a second pattern recognition feature to identify indications of sleep apnea;
calculating a second sleep apnea metric with the second pattern recognition feature based on indications of sleep apnea identified by the second pattern recognition feature in the physiological parameter data;
applying an arbitration with an arbitrator to the first and second sleep apnea metrics to determine a single sleep apnea metric; and
communicating the single sleep apnea metric to an output feature to display as an indication of the patient'"'"'s status and/or to control a therapeutic device.
