طراحی، ساخت و ارزیابی دستگاه تسهیل کننده ماساژ قلبی در احیای قلبی ریوی بزرگسالان

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: 80797). 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 30 emergency students. All statistical analyses were performed by SPSS 19 software using Pearson correlation and independent sample t-test. P-values lower than  0.05 were considered to be significant. Results: The mean age of all participants was 23.41±2.02 years, the mean height was 175±4.43 centimeters and the mean weight was 65.45±5.02 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 0.9). 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 5 cm) in 98% of participants. The numbers of massages were at least 100 massages per minute in 93% of participants. Conclusion: The results showed that designed system could be used as an effective tool to improve quality of cardiac massage in CPR.
