Mechanical CPR Device Shows Promise for Space Travel

Performing CPR in microgravity is extremely challenging. Current protocols on the ISS require a strenuous handstand technique. Researchers tested three mechanical chest compression devices in simulated microgravity, finding that the best device achieved a compression depth of 53mm, significantly better than the 34.5mm achieved with the handstand method (the effective depth is 50mm). This research could lead to improved space CPR guidelines, addressing the increased risk of cardiac events as space travel becomes more common.
