RECORDING MEDIUM, DEVICE, AND METHOD FOR SLEEP APNEA DETECTION
First Claim
1. A computer readable recording medium that stores therein a computer program for sleep apnea detection, the computer program causing a computer to execute:
- (a) recording external sound in environment;
(b) determining whether an audible sound or no sound is found in the external sound recorded at (a);
(c) analyzing, using information of intervals of the audible sound and no sound found at (b) and the external sound, a breathing pace indicating a cycle of a breathing estimated interval during which breathing is estimated; and
(d) extracting a silent interval within the breathing estimated interval based on the breathing pace analyzed at (c).

Abstract
A device for sleep apnea detection, includes an external sound recorder that records external sound in environment, a sound/silence determining unit that determines whether an audible sound or no sound is found in the external sound recorded in the external sound recorder, a breathing pace analyzing unit that analyzes, using information of intervals of the audible sound and no sound found by the sound/silence determining unit and the external sound, a breathing pace indicating a cycle of a breathing estimated interval during which breathing is estimated, and an apnea interval extracting unit that extracts a silent interval within the breathing estimated interval based on the breathing pace analyzed by the breathing pace analyzing unit.
