A study using volunteer doctors and nurses in simulated cardiac arrest resuscitations compared three different positions for delivering CPR: standing, kneeling by the patient, or standing on a “taboret”. They measured rescuer fatigue and effectiveness of CPR. They conclude that CPR is best performed in a kneeling position in that it maximizes duration of effective chest compression and minimizes back pain. The authors recommend if two or more experienced healthcare providers are available to perform CPR, alternating rescuers every 2 min in the kneeling or standing on a taboret positions, and every 1min in the standing on the floor position in order to minimize rescuer fatigue.
