  • System and Method for Arrhythmia Detection During An At Home Sleep Test
    Publication number: 20250064389
    Abstract: A method and system for detecting atrial fibrillations from a photoplethysmogram (PPG) signal. A method includes continuously generating a PPG signal measurement from a sensor of a PPG unit; generating a plurality of time frame samples based on the PPG signal measurement; generating, for each time frame sample, a plurality of heart rate (RR) intervals; determining an RR interval distribution for each time frame sample based on the plurality of RR intervals; and detecting at least one atrial fibrillation event based on the RR interval distribution for each time frame sample.

  • SYSTEM AND METHOD FOR PERFORMING AN AT-HOME PERIPHERAL ARTERIAL TONOMETRY
    Publication number: 20220125377
    Abstract: A system and method for performing a remote sleep apnea test is provided. The method includes: determining, based on sensor measurements generated during a sleep apnea test, an end of the sleep apnea test, wherein the sensor measurements are generated by at least one sensor; rendering at least one post-test question via a user interface within a threshold period of time since the end of the sleep apnea test is determined; and capturing at least one input provided by the patient in response to the rendered at least one post-test question.
