  • Systems, methods, and computer readable media for breathing signal analysis and event detection and generating respiratory flow and effort estimate signals
    Patent number: 12678095
    Abstract: Provided are systems, methods and computer-readable media for breathing signal analysis and event detection and systems, methods and computer-readable media for generating respiratory flow and/or effort signals from accelerometer signals using trained models. Breathing signal analysis may characterize at least one recorded signal as indicative of one of Obstructive Sleep Apnea (OSA) and Central Sleep Apnea (CSA). This analysis includes determining a frequency domain representation of an audio signal; sorting at least one frequency interval component into at least one corresponding frequency bin; determining a signal-to-noise ratio (SNR) signal for each frequency bin during a candidate time period; and determining an indication of an OSA event or a CSA event.
