“…A single manikin study (LOE 5) 222 demonstrated that medical students performed better-quality chest compressions during the first 2 minutes of continuous chest compressions compared with 15:2 CPR, although there was deterioration in quality after 2 minutes. An LOE 5 manikin study 223 of HCPs showed that the number of effective compressions (depth Ͼ38 mm) was the same if the rescuer changed every minute or every 2 minutes during 8 minutes of continuous chest compressions.…”

“…(6) Several manikin studies have revealed that BLS quality drops significantly during the first two minutes, especially the depth of compression, even when verbal feedback was provided in case of decreased compression depth. (7)(8)(9)(10)(11)(12)(13) These studies offer sophisticated insight into the process of BLS in terms of physical capabilities of providers. However, we still do not have the answers to the following questions: Do subjective parameters positively correlate with objective ones?…”

Rescuer fatigue does not correlate to energy expenditure during simulated basic life support

It is known that providing basic life support (BLS) may be limited by the physical capabilities of rescuers. The other factor that may affect BLS quality is its energy expenditure. Therefore, we decided to compare the energy expenditure of standard BLS with a compression-ventilation ratio of 30:2 (S-BLS) and compression-only BLS (CO-BLS) and assess the sensation of fatigue and perceived exertion associated with these activities.Methods. We conducted a simulation study on 10 healthy volunteers using a resuscitation manikin. Participants were randomly assigned to start with CO-BLS or with S-BLS, in accordance with recent guidelines. Later, every individual provided the other type of BLS. BLS was terminated in the event of exhaustion, impossibility to retain high-quality BLS or after 30 minutes of BLS. Energy expenditure was expressed as relative oxygen consumption (VO2/ kg) and area under the curve of all VO2/ kg measurements during each BLS procedure indexed to one minute (AUCVO2/kg min). All participants completed a survey to assess perceived intensity of exertion by Borg, and sensation of general fatigue by visual analogue scale.Results. Maximal VO2/kg (23.16±3.94 vs. 20.17±2.14 ml/kg/min, p=0.049) and AUCVO2/kg min (18.90±3.13 vs. 15.91±2.07 ml/min3; p=0.021) during S-BLS were significantly higher compared to CO-BLS. Conversely, a more intense rate of perceived exertion (16.6±2.0 vs. 13.8±1.2, p=0.001) and sensation of general fatigue (86.5±10.8 vs. 75.0±14.3, p=0.058) were associated with CO-BLS. Neither sensation of general fatigue, nor perceived exertion correlated with energy expenditure.Conclusions. Energy expenditure of S-BLS was higher than of CO-BLS in our study, while sensation of fatigue and perceived exertion reflected the opposite association.

This study was conducted to examine the differences of the quality of chest compression between 10 cm higher position of rescuer's knee from the bottom and its bottom position during implementation of CPR. It selected randomly subjects out of 66 students who attend the Dept. of Emergency Medical Technology in G college, G metropolitan city as the first grader and divided them into 31 experimental group and 32 control group from Nov. 8 to 9, 2011. Mattress was spread 10 cm higher from the bottom(material: B4 Copy Paper) and on the bottom(material: PVC, size: 185×125×0.65 cm) and only chest compression was conducted for 2 minutes. Experiment was conducted with 1 Resusci Anne mannequin and the results of experiment were recorded with Laerdal PC Skill Reporting System. Data collected were analyzed with x 2 -test and Fisher's exact probability test using SPSS 14.0 for Window, Mann-Whitney U-test, and Wilcoxon signed rank test. As a result of the study, it was found that 10 cm higher position of rescuer knee from the bottom than the bottom position and group below 170 cm in their height and 65 kg in their weight were more effective in proper depth of chest compression and average chest compression depth.
