Sleep apnea risk evaluation
First Claim
1. A system that monitors respiratory events of a patient, the system comprising:
- a pulse oximetry sensor and circuitry that detects oxyhemoglobin saturation and pulse rate of the patient of the patient and produces corresponding data signals;
wherein said pulse oximetry sensor is mounted on a physiological monitoring system that is affixed on said patient'"'"'s head such that the pulse oximetry sensor detects said patient conditions and produces said data signals, thereby monitoring said patient'"'"'s condition.

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.
