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.
