Current CPR techniques don’t consider the individual physiology of the patient – such as chest size, blood perfusion signals, and cardiac arrest cause – despite the importance of these factors for patient outcomes. Our automated mechanical chest compression device for cardiopulmonary resuscitation (“Smart” CPR) adjusts thrust depth and rate to the current needs of the patient. Although there are other automated CPR systems on the market, all of them give fixed compressions across patients and time, so ours is the only system that can provide shallower compressions for a child or more rapid compressions for a patient in decline.

Technology Description

Our device compresses the patient’s chest through a linear actuator controlled by a SmartMotor™. The position of the actuator is calculated with high precision by an optical encoder and a potentiometer. Our device could be linked to a cardiac monitoring system – which is already ubiquitous across ambulance fleets – that is capable of measuring electrocardiogram and perfusion signals. Then these signals could be used in real time to adjust the parameters of the Smart CPR compression arm. Animal studies have shown that Smart CPR provides greater blood perfusion and leads to more favorable survival rates from cardiac arrest.
