Depth and rate of chest compression in CPR simulation during 10-minute continuous external cardiac compression
Journal Title: Annales Academiae Medicae Silesiensis - Year 2017, Vol 71, Issue
Abstract
INTRODUCTION: External cardiac massage has been a basic CPR maneuver for years. The aim of the study was to assess the quality of chest compression during a real-time continuous cardiac compression simulation on a cardio-pulmonary resuscitation mannequin (considering medical rescuer experience and BMI). MATERIAL AND METHODS: This was a prospective study involving 17 medical rescuers, and 21 Medical Rescue stu-dents and university lecturers. During the simulation the participants performed continuous external cardiac compres-sion for 15 minutes or until the refusal to continue. The depth and rate were analyzed at 60-second periods, leading to average values of cardiopulmonary resuscitation effectiveness. The analysis covered complete research data gathered in real time (10 minute periods). RESULTS: The average compression depth significantly decreased from the first (40.66 SE ± 0.80 mm) to the fourth minute of the study (38.21 SE ± 0.95 mm). The average compression rate was significantly different between the initial values (120.97 SE ± 2.83/min) and the sixth minute of the study (123.69 SE ± 2.55/min). The average com-pression depth amounted to n 36.03 SE ± 1.22 mm in non-professionals and 40.06 SE ± 1.37 mm in professionally active participants. In the participants with a BMI > 25, the only differentiating point in time was the beginning of the task when the average compression depth was 41.97 SE ± 1.12 mm. In the participants with a BMI < 25, there was a gradual decrease in the compression depth within the initial four minutes of the task. CONCLUSION: Rescuer body mass is an important factor influencing proper chest compression depth during conti-nuous cardiac compression. Professional rescuers are capable of performing continuous cardiac compression longer than non-professionals, at the same time maintaining acceptable sternum deflection and compression rate.
