Up-down hand position switch may delay the fatigue of non-dominant hand position rescuers and improve chest compression quality during cardiopulmonary resuscitation: a randomized crossover manikin study.

Previous studies have shown improved external chest compression (ECC) quality and delayed rescuer fatigue when the dominant hand (DH) was in contact with the sternum. However, many rescuers prefer placing the non-dominant hand (NH) in contact with the sternum during ECC. We aimed to investigate the effects of up-down hand position switch on the quality of ECC and the fatigue of rescuers during cardiopulmonary resuscitation (CPR).

Awareness and attitudes of Chinese students towards cardiopulmonary resuscitation.

Background: A large number of sudden cardiac arrests occur annually, but the worldwide survival rate is less than 1%. Early initiation of bystander Cardiopulmonary resuscitation (CPR) would improve the survival rate of out-of-hospital sudden cardiac arrests. Students play an important role as bystanders on and off campus both now and in the future.
