Smart wearable could better measure blood loss

A wearable device could one day allow EMTs, military medics, and ER doctors to assess more accurately assess blood loss due to hemorrhage.

Better blood loss assessments could let health professionals better treat victims of car accidents, gunshot wounds, and battlefield injuries.

Researchers have shown the device can measure seismic vibrations in the chest cavity and detect changes in the timing of heartbeats to accurately assess blood loss.

The knowledge, developed in the laboratory, could potentially lead to development of a smart wearable device that ambulance crews and medics could carry or have available in emergency rooms and surgical facilities.

“We envision a wearable device that could be placed on a person’s chest to measure the signs that we...
