APNEA AND HYPOVENTILATION ANALYZER

摘要

A device is operative to quantify the severity of changes in ventilation strength and amplitude by monitoring the effort and efficiency of breathing activity, and classifying the source of apnea as either central or obstructive.

主权项

1. A device for monitoring and detecting apnea comprising:
a local acceleration chest sensor mountable on a chest of a patient for sensing local accelerations, called sensed local accelerations; data amplification and filtration components; a data acquisition system and data storage for data analysis and comparison with past data; and a processor for calculating a respiratory effort index based on said sensed local accelerations and classifying a source of apnea as either central or obstructive by comparing the respiratory effort index to a baseline value defined when no apnea is present, wherein said respiratory effort index increases above the baseline for obstructive apnea and decreases below the baseline for central apnea.
