METHODS AND SYSTEMS FOR DETERMINING EFFECTIVENESS OF RESPIRATION IN INDIVIDUALS

摘要

The present invention relates to systems and methods for comparing photoplethysmography (PPG) signals from an individual with signals from a secondary respiration sensor secured to the individual to determine whether effective respiration has occurred or whether the individual has apnea, hypopnea, or other respiratory distress.

1. A method of monitoring the effectiveness of respiration in an individual, comprising
determining whether a respiratory attempt in the individual occurred within a predefined time period based on photoplethysmography (PPG) signals obtained from a PPG sensor secured to the individual; determining whether a ventilation occurred within the predefined time period using a secondary respiration sensor; and comparing the determination of the respiratory attempts based on the PPG signals with the determination of the ventilation based on the secondary respiration sensor to assess whether the individual's respiratory attempts are effective.
