SYSTEMS FOR SLEEP APNEA DETECTION FROM BREATHING SOUNDS |
摘要 |
A system is disclosed for detecting obstructive sleep apnea in subject. The system includes ran electronic stethoscope for placement, at the subject's suprasternal notch, providing an electrical signal representative of the sounds detected by the head of the electronic stethoscope within a frequency range; a processor for determining an obstructive sleep apnea index based on a ratio of the amount of the electrical signal that is associated with a frequency below a cut-off frequency with respect to a total amount of energy associated with the entire frequency range; and a display for identifying the subject as having obstructive sleep apnea if the obstructive sleep apnea index is above a window maximum or below a window minimum. |
