Design of a mechanical CPR device: Automated CPR To-Go (ACT)

Cardiopulmonary resuscitation (CPR) is the first step in treating victims of sudden cardiac arrest. Though manual CPR has been prevalent for many years, mechanical CPR has proven to be easier for the rescuer, safer for the patient, and more effective in pumping blood through the body. Current mechanical CPR devices, such as the AutoPulse by Zoll, Inc., utilize a load-distributing band to apply circumferential chest compressions. However, it is very expensive and heavy, thus prohibiting its distribution to the general public. We propose to fabricate a mechanical CPR device, Automated CPR To-Go (ACT), which will be cost-effective and lightweight. The device will provide 2-inch deep anterior-posterior chest compressions to victims and will be able to be used by rescuers with minimal training. Material, electrical, and mechanical factors were taken into consideration when designing ACT. The major components of the device include the board, motor assembly, belt assembly, housing unit, microprocessor, and power source. Currently, ACT has been designed, and the materials have been chosen for its development. Upon completion of the project, it is expected that the device will be able to achieve the aforementioned goals of anterior-posterior displacement, easy application, and will be distributable to the general public.
