Chest/wrist wearable system predicts, aims to prevent, asthma attacks

North Carolina State researchers are developing a multi-sensor wearable monitoring system meant to predict and prevent asthma attacks. A chest-worn patch  track one’s respiratory rate, skin impedance and wheezing in the lungs. A wristband monitors volatile organic compounds and ozone in the air, ambient humidity, and temperature, as well as a a wearer’s movements, heart rate and blood oxygen level. Users must also breathe into a spirometer several times per day to measure lung function.

An algorithm  identifies which environmental and physiological variables are effective at predicting asthma attacks. Wearers receive notifications suggesting a change in environment or activity to prevent an attack.
