Estimating Tidal Volume Using Mobile Devices

This abstract first appeared for US patent application 20240423498 titled 'Estimating Tidal Volume Using Mobile Devices

Original Abstract Submitted

in one embodiment, a method includes detecting, by a motion sensor of a mobile device worn by a user, multiple motion signals, each representing a motion of the user about one of a number of mobile-device axes defined by an orientation of the mobile device. the method further includes determining, for each of the multiple mobile-device axes, a ballistocardiogram (bcg) signal based on the motion signal corresponding to that mobile-device axis; selecting, based on a strength of the determined bcg signals, one or more particular mobile-device axes and corresponding motion signals for estimating a user's tidal volume; determining, based on the one or more selected motion signals, one or more breathing features; and estimating, by providing the one or more breathing features to a trained machine-learning model, the user's current tidal volume.
