Smart Devices Detect Agonal Breathing in Cardiac Arrest

JAMA. 2019;322(6):495. doi:10.1001/jama.2019.11648

Roughly half of people who experience a cardiac arrest demonstrate agonal breathing, a brainstem reflex during severe hypoxia. Researchers at the University of Washington in Seattle are teaching smart devices to detect this audible biomarker, often described as gasping breaths. Agonal breathing sounds from Seattle-area 911 cardiac arrest calls were used to train and validate a detection system recently introduced in npj Digital Medicine.
