Abstract: A method to evaluate respiratory health includes obtaining (i) one or more lung acoustic signals and (ii) one or more bioimpedance spectroscopy signals, wherein the one or more acoustic signals and the one or more bioimpedance spectroscopy signals are concurrently acquired over multiple respiratory cycles; generating values for (i) a first set of plurality of statistical features and/or a first set of time-frequency domain features using the obtained one or more lung acoustic signals and (ii) a second set of plurality of statistical features and/or a second set of time-frequency domain features using the obtained one or more bioimpedance spectroscopy signals; and generating, using one or more trained classifiers, a respiratory health value representative of a respiratory health of the patient by application of the values of the first and second sets of plurality of statistical features and time-frequency domain features to the one or more trained classifiers.

Abstract: A conformal patch device can be provided to a patient. The patch device can include sensors configured to be positioned over a chest of a patient. The sensors can include PPG sensors, ECG sensors, and SCG sensors. The conformal patch device can adhere to a single continuous area of the chest. Some sensors may attached to a viscoelastic substrate to achieve mechanical isolation from other patch components. The conformal patch device can capture measurements from the sensor doing a time window sufficient enough to detect disordered breathing. The system can determine disordered breathing and related cardiorespiratory parameters during the time window for the patient using the sensor measurements.
