Impact of rescuer position, arm angle, and anthropometric variables on muscle fatigue during cardiopulmonary resuscitation: an international multicentric randomized crossover simulation study
Arm angle is a key determinant of rescuer muscle fatigue, with 105° increasing fatigue compared to 90°. Rescuer position alone was not significant, though fatigue was more pronounced in kneeling and elevated positions. Taller and heavier rescuers demonstrated greater endurance but remained affected by suboptimal arm angles.
