Abstract

Objective

The International Liaison Committee on Resuscitation (ILCOR) and the Australian Resuscitation Council (ARC) recommend that high-quality cardiopulmonary resuscitation (CPR) is the key to performance outcomes, emphasising compression and rotation through this process. The proposed study has a two-stage approach to evaluating cardiopulmonary resuscitations effectiveness by out-of-hospital practitioners. The first stage aimed to evaluate the influence of providing real-time biofeedback using the Q-CPR system on the provision of CPR by student paramedics. Secondly, the study quantified the effects of physical fatigue on maintaining quality cardiopulmonary resuscitation performed by paramedic students.

Methods

Forty paramedic students completed cardiopulmonary resuscitation on an instrumented manikin with and without audio-visual biofeedback (Q-CPR within the Phillips MRx defibrillator) in a balanced cross-over fashion. To quantify the quality of cardiopulmonary resuscitation concerning the percentage of applied compressions that meet the current ARC guidelines in terms of rate, depth, and recoil time, a manikin feedback system (SimMan 3 G; Laerdal, Norwegian) was used.

Results

When using the Q-CPR prompt with bio-feedback, overall, the depth and fatigue levels increased significantly, highlighting a correlation between correct depth and increased fatigue.

Conclusions

Audio prompts improved compression depth; however, fatigue levels increased. The depth during manual compression compared to the Q-CPR prompt was not statistically significant.

评估学生护理人员对模拟心脏骤停病例的疲劳测量和心肺复苏质量

目的国际复苏联络委员会（ILCOR）和澳大利亚复苏理事会（ARC）建议，高质量的心肺复苏（CPR）是取得成绩的关键，强调在这个过程中进行按压和旋转。这项拟议的研究采用两阶段方法来评估院外从业者的心肺复苏效果。第一阶段旨在评估使用Q-CPR系统提供实时生物反馈对学生护理人员提供CPR的影响。其次，该研究量化了身体疲劳对维持护理学生心肺复苏质量的影响。方法40名护理学生在装有和不带有视听生物反馈（Phillips MRx除颤器内的Q-CPR）的仪器化人体模型上以平衡交叉的方式完成心肺复苏。为了量化心肺复苏的质量，即在速率、深度和反冲时间方面符合当前ARC指南的按压百分比，使用了人体模型反馈系统（SimMan 3G；挪威Laerdal）。结果当使用带有生物反馈的Q-CPR提示时，总体而言，深度和疲劳水平显著增加，突出了正确的深度与疲劳增加之间的相关性。结论音频提示压缩深度提高；然而，疲劳程度增加了。与Q-CPR提示相比，手动按压过程中的深度没有统计学意义。

期刊介绍： Australasian Emergency Care is an international peer-reviewed journal dedicated to supporting emergency nurses, physicians, paramedics and other professionals in advancing the science and practice of emergency care, wherever it is delivered. As the official journal of the College of Emergency Nursing Australasia (CENA), Australasian Emergency Care is a conduit for clinical, applied, and theoretical research and knowledge that advances the science and practice of emergency care in original, innovative and challenging ways. The journal serves as a leading voice for the emergency care community, reflecting its inter-professional diversity, and the importance of collaboration and shared decision-making to achieve quality patient outcomes. It is strongly focussed on advancing the patient experience and quality of care across the emergency care continuum, spanning the pre-hospital, hospital and post-hospital settings within Australasia and beyond.
