How should we teach cardiopulmonary resuscitation? Randomized multi-center study

Abstract

Background: A 2017 update of the resuscitation guideline indicated the use of cardiopulmonary resuscitation (CPR) feedback devices as a resuscitation teaching method. The aim of the study was to compare the influence of two techniques of CPR teaching on the quality of resuscitation performed by medical students. Methods: The study was designed as a prospective, randomized, simulation study and involved 115 first year students of medicine. The participants underwent a basic life support (BLS) course based on the American Heart Association guidelines, with the first group (experimental group) performing chest compressions to observe, in real-time, chest compression parameters indicated by software included in the simulator, and the second group (control group) performing compressions without this possibility. After a 10-minute resuscitation, the participants had a 30-minute break and then a 2-minute cycle of CPR. One month after the training, study participants performed CPR, without the possibility of observing real-time measurements regarding quality of chest compression. Results: One month after the training, depth of chest compressions in the experimental and control group was 50 mm (IQR 46-54) vs. 39 mm (IQR 35-42; p = 0.001), compression rate 116 CPM (IQR 102-125) vs. 124 CPM (IQR 116-134; p = 0.034), chest relaxation 86% (IQR 68-89) vs. 74% (IQR 47-80; p = 0.031) respectively. Conclusions: Observing real-time chest compression quality parameters during BLS training may improve the quality of chest compression one month after the training including correct hand positioning, compressions depth and rate compliance.

“Motorcycle Ambulance” the Policy to Promote Health and Sustainable Development in Large Cities

“…The health sustainable development policy with the use of an emergency motorcycle plays an important role in reducing access time to patients. In addition, the installation of the AED on the motorlance increases the chance of survival which is considered a worthwhile investment [51][52][53]. In countries with limited budgets, installing AEDs in public areas is an important policy that both the government and private sectors should pay attention to and jointly develop, but during the waiting period for development, the application of available resources by bringing an emergency motorcycle to install an AED would be beneficial to people in the community, especially patients with out-of-hospital cardiac arrest.…”

Chest compressions quality during sudden cardiac arrest scenario performed in virtual reality

“…Participants did not reach the minimum value of 50 mm recommended by the guidelines but obtained results do not differ from those presented in other studies conducted in training conditions. [ 19 – 23 ] It is worth noticing that CCs depth was significantly lower in VRS group when VRS was the first scenario. Highly statistically important difference was also found in in percentage of FCR component ( P < .01).…”

Chest Compression Methods Simulated Covid-19 Patient Resuscitation: A Randomized Cross-Oversimulation Trial

“…By showing the parameters of chest compression in real time, they improve the quality of compression. As indicated by the study by Katipoglu et al observing real-time chest compression quality parameters during Basic Life Support training may improve the quality of chest compression one month after the training including correct hand positioning, compressions depth and rate compliance [28]. The study by Buléon et al shows the use of CPR feedback devices, especially in the aspect of prolonged resuscitation [29].…”

“…The manual chest compression rate was 117 (IQR;(112)(113)(114)(115)(116)(117)(118)(119)(120)(121)(122)(123)(124)(125) compressions per minute (CPM) and was higher than with TrueCPR feedback device -107 (IQR;(102)(103)(104)(105)(106)(107)(108)(109)(110)(111)(112)(113)(114)(115) p = 0.017). Full chest relaxation in the manual's chest compression technique (without TrueCPR) was 33 (IQR;(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)% and was lower than with chest compression with TrueCPR feedback device -58 (IQR; 40-75)% (p=0.002).Conclusions: We conclude that a TrueCPR feedback device improves chest compression quality during simulated COVID-19 resuscitation performed by medical students wearing PPE-AGP.…”
