Background and Objectives: Cardiac massage is the first and most important step during Cardio Pulmonary Resuscitation (CPR). Effective massage restores blood flow to the brain and heart and plays a remarkable role in a successful CPR. Exhaustion of treatment team during resuscitation is one of the factors which may lead to reduced quality of resuscitation massages or failure in some cases. The aim of this study was to design, construct and evaluate a new
cardiac massage facilitator to improve the quality of CPR in adult patients.
Methods: In this study, the
massage facilitator was designed and registered as a glove which was worn by rescuers during
cardiac massage (number of invention: ۸۰۷۹۷). A load cell sensor was placed under the surface of the glove and the facilitator could be displayed number and depth of massage in centimeters. In order to evaluate the efficiency of the designed system, an experimental study was conducted among ۳۰ emergency students. All statistical analyses were performed by SPSS ۱۹ software using Pearson correlation and independent sample t-test. P-values lower than ۰.۰۵ were considered to be significant.
Results: The mean age of all participants was ۲۳.۴۱±۲.۰۲ years, the mean height was ۱۷۵±۴.۴۳ centimeters and the mean weight was ۶۵.۴۵±۵.۰۲ kilograms. The instrument validity was evaluated using standard validation method of concurrent validity. Our findings revealed a significant correlation between the
cardiac massage facilitator and Sim Pad system (more than ۰.۹). Accordingly, the validity of
cardiac massage facilitator was confirmed. While assessing the efficient massage criteria during
cardiac massage facilitator utilization, the massage possessed suitable depth (less than ۵ cm) in ۹۸% of participants. The numbers of massages were at least ۱۰۰ massages per minute in ۹۳% of participants.
Conclusion: The results showed that designed system could be used as an effective tool to improve quality of
cardiac massage in CPR.
