Polish team develops restraint system to make CPR possible in weightlessness

Polish researchers have built a device that holds both the rescuer and the patient in place during resuscitation in microgravity. The CMRS/ARS system is in engineering tests and could be used on future Moon and Mars missions.

Why CPR is hard in space

In weightlessness, a rescuer pressing on a patient's chest has nothing to push against except the patient, so each compression sends the rescuer drifting away (Jak ratować życie bez grawitacji? Oto nowy wynalazek Polaków – tech.wp.pl). That makes it difficult to apply enough force and depth.

What the system does

The device, developed under the names CMRS and ARS, is designed to fix both people in place. It has handholds for the rescuer and components that secure the patient quickly, giving the rescuer a rigid back support so compressions can be performed even without a stable surface nearby.

Development and testing

The work involves teams linked to the Collegium Medicum of the Jagiellonian University and the Military Institute of Aviation Medicine. According to Arkadiusz Trzos of the Collegium Medicum, the project is at the engineering-testing stage, and its developers are seeking permission to run trials during parabolic flights (Polacy opracowali niezwykłe urządzenie.

Possible use

The system is aimed at future missions to the Moon and Mars, where medical help may be far away. Reports say the technology has drawn interest from specialists at NASA, though no agreement on its use has been announced (Resuscytacja w kosmosie możliwa dzięki Polakom.
