Sleep apnea risk evaluation
First Claim
1. In a system for evaluating a patient'"'"'s risk of sleep apnea, the improvement comprising:
- an expert computing system for comparing abnormal respiratory events of a patient with a sleep apnea risk database of sleep apnea risk data, comparing clinical information of the patient with said sleep apnea risk database, and generating a report of the patient'"'"'s risk of sleep apnea, said abnormal respiratory events being based upon monitored physiological information from the patient, said monitored physiological information including pulse oximetry data from the patient, and said patient'"'"'s clinical information being derived from a questionnaire identifying sleep apnea risk factors of the patient.

Abstract
In a technique for collecting and analyzing physiological signals to detect sleep apnea, a small light-weight physiological monitoring system, affixed to a patient'"'"'s forehead, detects and records the pulse, oximetry, snoring sounds, and head position of a patient to detect a respiratory event, such as sleep apnea. The physiological monitoring system may contain several sensors including a pulse oximeter to detect oximetry and pulse rate, a microphone to detect snoring sounds, and a position sensor to detect head position. The physiological monitoring system also can contain a memory to store or record the signals monitored by the mentioned sensors and a power source. The physiological monitoring system may be held in place by a single elastic strap, thereby enabling a patient to use the system without the assistance of trained technicians.
