CHEST COMPRESSION MONITOR WITH ROTATIONAL SENSING OF COMPRESSIONS FOR DISCRIMINATION OF CPR MOVEMENT FROM NON-CPR MOVEMENT

摘要

A chest compression monitor for measuring the depth of chest compressions achieved during CPR. A sensor of the chest compression monitor is disposed within its housing such that compression of the housing due to CPR compressions, and its resultant deformation, is detected by the sensor and used by the control system as the starting point for calculating chest compression depth based on an acceleration signal indicative of the downward displacement of the chest.
