Audio and video nearables for monitoring respiratory rate in sleeping dogs.

ABSTRACT: Continuous monitoring of respiratory rate (RR) in dogs is critical for early detection of respiratory and cardiac conditions. However, current solutions are often invasive, or impractical for at-home use. This study aims to evaluate four smartphone-based nearable methods (two audio-based and two video-based) for non-invasive RR monitoring in sleeping dogs. 27 dogs were recorded during natural sleep using four different setups: (A) audio with earphone microphone, (B) audio with smartphone microphone, (C) video from a top-down perspective, and (D) video from a lateral view. Signals were processed to estimate RR. Manual breath counting served as the reference. All methods demonstrated good agreement with the reference. RMSE ranged from 1.1 to 2.2 bpm, MAE from 0.7 to 1.5 bpm. Video-based meth
