Abstract

In collaboration with NASA's Reduced Gravity Education Flight Program, the effectiveness of ACD-CPR was compared to traditional CPR in a microgravity environment. Elements compared included fluid flow output in a simulated chest cavity, depth and rate of compressions achieved, time required for implementation, and feasibility to perform compressions. ACD-CPR varies from traditional CPR in that it uses a small, mechanical device, similar to a suction cup, to raise the chest wall after compression, allowing decompression of the chest. Testing showed that rate and compression standards established by the American Heart Association could be reached doing ACD-CPR in microgravity. Flow data showed that the fluid flows similarly in a 0g environment as in a 1g environment. Average time required for implementation was reduced from two minutes, at which point brain damage is likely, to twenty-five seconds. Greater efficiency in medical emergency procedures will be crucial for long-term missions.
