A new method for the performance of external chest compressions during hypogravity simulation.

Introduction: 2015 UK resuscitation guidelines aim for 50-60 mm depth when giving external chest compressions (ECCs). This is achievable in hypogravity if the rescuer flexes and extends their arms during CPR, or using a new method trialed; the 'Mackaill-Russomano' (MR CPR) method.

Methods: 10 participants performed 3 sets of 30 ECCs in accordance with 2015 guidelines.
