Mechanical CPR - The Pulse of the Future?
A new mechanical device is being studied by the Worthington Division of Fire to aid in the effectiveness in the life-saving technique of CPR. The division is currently participating in a research project that tests a new product called ASPIRE, or AutoPulse Assisted Prehospital International Resuscitation.
Instead of the medic using the palms of his or her hands to apply compressions on a heart attack victim's chest to get the heart pumping again, they can strap on the ASPIRE, which generates a strong and consistent pulse toward the heart. The ASPIRE provides a circulating blood volume that is close to 90% of a normal beating heart, compared to 15-20% for manual chest compressions.
The device measures the victim's body size and applies the appropriate strength of compression. It also works in conjunction with the portable Automated External Defibrillators, which apply electrical shock to the victim's heart in case of cardiac arrest.
The field study is designed to determine how effective the device is at changing cardiac arrest survival rates and to determine if the device is practical for field use.
