Assessing student paramedics' measurements of fatigue and quality of cardiopulmonary resuscitation on a simulated cardiac arrest case

Abstract

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