Problem: Cardiac arrest is one of the most serious medical conditions in Sweden, affecting thousands of people every year, making it a significant public health challenge. Research shows that the quality of cardiopulmonary resuscitation (CPR) performance varies between different healthcare facilities, suggesting a need for improved methods and aids to standardize and increase the quality of CPR. Background: CPR Guide is a physical product intended to be placed on the chest of a person in need of CPR to assist the rescuer in real-time by providing visual and auditory feedback on the CPR performance. The aid follows international guidelines regarding the performance of CPR. Previous studies on similar CPR aids have shown positive effects.
Research question: ”How does the use of the sensor-based cardiopulmonary resuscitation aid CPR Guide affect how well medically trained people perform cardiopulmonary resuscitation compressions?”.
Research method: A controlled experiment was performed at a clinical training center at Södersjukhuset in Stockholm. During the experiment, 35 medically trained people performed CPR compressions on a practice manikin equipped with built-in measurement functionality, with and without the help of CPR Guide. This method allowed a direct comparison of the CPR performances, with a specific focus on compression depth, compression tempo, and complete release of the chest after each compression, which are three critical components of performing good quality CPR. The collected data was analyzed using a number of Wilcoxon Signed Ranks tests to compare the two performances.
Results: The analysis showed that the use of CPR Guide led to statistically significant improvements in compression depth and tempo. The average percentage of compressions with correct depth increased from 57.26 % to 84.89 % and the average percentage of compressions with correct tempo increased from 65.20 % to 82.20 %. These results confirm the results of previous research on other sensor-based CPR aids. In contrast, the average percentage of compressions with complete release of the chest decreased from 86.54% to 70.11%. Conclusion: The use of the sensor-based cardiopulmonary resuscitation aid CPR Guide improves compression performance by medically trained people regarding depth and tempo, but worsens performance regarding complete release of the chest.
