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.
