7 - CPR Personal Trainer: a low-cost training tool with objective feedback







Introduction and Aim In a sudden cardiac arrest, early cardiopulmonary resuscitation (CPR), with emphasis on chest compressions, is a fundamental step in the Chain of Survival. However, overall performance remains poor suggesting that frequent training is needed to ensure consistent, effective delivery of CPR and therefore better outcomes[1]. This abstract describes a low-cost prototype that serves as a CPR Personal Trainer (CPR.PT), expecting to facilitate broad and regular training and improve long-term skills retention. Methods CPR Personal Trainer consists in a standard (commercialized) CPR training manikin instrumented with off-the-shelf sensors connected to a pre-processing unit and information system. The signals are analysed and relevant data on performance and effectiveness of chest compressions and ventilations is extracted, namely: chest compressions indicators (hands position, rate, depth and chest recoil), ventilations indicators (head hyperextension and air inflow) and general indicators (hands off-time and correct 30:2 cycles). An overall score based on these indicators is calculated providing a quantitative evaluation of the performance. A second interface gives specific feedback and recommendations to promote skills improvement, together with video demonstrations. Results A preliminary study[2] compared the effectivity of the CPR.PT (prototype only, no instructor) against traditional training method (instructor-based). The intervention group (CPR.PT, no instructor) showed significant improvements regarding skills’ acquisition and achieved similar global scores as the control group (instructor-based traditional training). Conclusions It is expected that CPR.PT encourages more frequent training sessions, as it reduces the need for a permanent instructor. It allows regular training with objective feedback, outside formal training courses, not only in healthcare institutions but also in firefighters departments, nursing homes, schools and general public institutions.
