FUSION OF DATA FROM MULTIPLE SOURCES FOR NON-INVASIVE DETECTION OF RESPIRATORY PARAMETERS

摘要

Provided herein are methods and systems for validating and interpreting respiratory signals in order to provide comprehensive non-invasive methods to monitor patients at risk for respiratory depression and apnea. In the present invention, data from multiple respiratory monitoring technologies (or from multiple channels of one monitoring technology) is fused so that the patient's true respiratory state may be elucidated.

主权项

1. A method of determining the respiratory status of an individual, comprising monitoring a PPG waveform from a PPG sensor secured to a central source site of an individual over time;
monitoring a waveform indicative of nasal air flow of the individual; comparing a portion of the PPG waveform with a corresponding portion of the waveform indicative of nasal airflow; and determining a respiratory parameter or condition based on the similarity and/or differences between the PPG waveform and the waveform indicative of nasal airflow.
