Does the quality of chest compressions deteriorate when the chest compression rate is above 120/min?

Abstract

The study showed conflicting results in the quality of chest compression including chest compression depth and chest recoil by chest compression rate. Further evaluation regarding the upper limit of the chest compression rate is needed to ensure complete full chest wall recoil while maintaining an adequate chest compression depth.

Does the use of cardiopulmonary resuscitation feedback devices improve the quality of chest compressions performed by doctors? A prospective, randomized, cross-over simulation study

“…In turn, studies by Lee et al [26] showed that the frequency of compressions over 120/min was associated with a higher depth of compressions than the frequency of compressions indicated in the guidelines for resuscitation [4]. Zou et al [27] indicated the most optimal frequency of CCs is a frequency of 120/min [26,27]. In the present study, the compression rate performed without the device by trainee doctors was 129 cpm, while in the case of using the TrueCPR device it was 112 cpm.…”

Rate at 120/min provides qualified chest compression during cardiopulmonary resuscitation

“…Cardiopulmonary resuscitation (CPR) after SCA is known to reduce mortality and leads to approximately a 3-fold increase in post-SCA discharge from hospitals, potentially negating its significant health care burden [1]. The quality of prehospital resuscitation is important to achieve return of spontaneous circulation (ROSC) [2]. In an effort to improve SCA outcomes, recent investigations have focused on the quality of CPR [3,4].…”

The effect of chest compression frequency on the quality of resuscitation by lifeguards. A prospective randomized crossover multicenter simulation trial

“…Lee et al [25] analyzed chest compression parameters in 322 students participating in a cardiopulmonary resuscitation contest. The authors noticed that chest compression depth was proportional to chest compression rate, though with significantly more incomplete chest recoils at a rate of more than 120 CPM.…”
