Kneeling Posture With a Kneeling Stool During Cardiopulmonary Resuscitation in Hospital

To perform chest compression (CC) in the kneeling posture in hospital, we designed a stage with stairs, named the 'kneeling stool', on which a CC performer kneels beside a patient on a bed.This work is the validation study to demonstrate that the kneeling stool could be used for high quality hospital cardiopulmonary resuscitation (CPR) with the kneeling posture. We hypothesized that the quality of chest compression with a kneeling posture using the kneeling stool is equal to or superior to CC with a standing posture using the height adjustment mechanism of the bed.
