“…A study using CPR quality data stored by automated external defibrillators showed limitations including Emergency Medicine International no bystander information and inclusion bias [14]. Assessment of simulated CPR could not reflect the situation of a real population [15,16]. Takei et al evaluated bystanders in a single area [11].…”

“…Takei et al reported that high-quality CPR was not related to bystander age; however, a relationship between high-quality CPR and the younger age group was observed in our population. In a study on health-care providers, elderly providers (>65 years) showed decreased CPR quality compared to younger providers [15]. e elderly are generally physically weaker than younger people.…”

Bystander cardiopulmonary dresuscitation (CPR) improves the survival and neurological outcomes of sudden cardiac arrest patients. The rate of bystander CPR is increasing; however, its performance quality has not been evaluated in detail. In this study, emergency medical technicians (EMTs) in the field evaluated bystander CPR quality, and we aimed to investigate the association between bystander information and CPR quality. This retrospective cohort study was based on data included in the Smart Advanced Life Support (SALS) registry between January 2016 and December 2017. We included patients older than 18 years who experienced an out-of-hospital cardiac arrest (OHCA) due to medical causes. Bystander CPR quality was judged to be “high” when the hand positions were appropriate and when compression rates of at least 100/min and compression depths of at least 5 cm were achieved. Among 6,769 eligible patients, 3,799 (58.7%) received bystander CPR, and 6% of bystanders performed high-quality CPR. After adjustment, the occurrence of cardiac arrest at home (adjusted odds ratio (aOR), 95% confidence interval (CI); 0.42, 0.27–0.64), witnessed cardiac arrest (1.45, 1.03–2.06), and younger bystander age all showed associations with one another. High-quality CPR led to a 4.29-fold increase in the chance of neurological recovery. In particular, high-quality CPR in patients aged 60 years showed a significant association compared with other age groups (7.61, 1.41–41.04). The main factor affecting CPR quality in this study was the age of the bystander, and older bystanders found it more difficult to maintain CPR quality. To improve the quality of bystander CPR, training among older bystanders should be the focus.

“…As BMI was similar in both female and male subjects in our cohort, this characteristic cannot account for the shallower depth by female compressors. A recently published study by Lin et al [7] examined pre-hospital provider specific factors that could affect CPR quality and did find that BMI, along with exercise, played a role in CPR quality. However, their study had a statistically significant difference in their subjects' BMI, while our study did not find a difference between our subjects' BMI.…”

“…Similarly, whether characteristics related to the gender of the CPR provider have an effect on the quality of CPR delivered has not been clearly determined. [4,7] We hypothesized that chest compression (CC) depth would be less in older aged subjects and in females. Understanding differences in lay provider CPR based on specific provider characteristics could help instructors target education and practice sessions specific to those demographics to improve lay provider CPR quality.…”

BACKGROUND: Few studies have examined the association of layperson characteristics with cardiopulmonary resuscitation (CPR) provision. Previous studies suggested provider characteristics, including age and gender, were associated with CPR quality, particularly chest compression (CC) depth. We sought to determine the association of subject characteristics, including age and gender with layperson CPR quality during an unannounced simulated CPR event. We hypothesized shallower CC depth in females, and older-aged subjects. METHODS:As part of a larger multicenter randomized controlled trial of CPR training for cardiac patients' caregivers, CPR skills were assessed 6 months after training. We analyzed associations between subject characteristics and CC rate, CC depth and no-fl ow time. Each variable was analyzed independently; signifi cant predictors determined via univariate analysis were assessed in a multivariate regression model. RESULTS:A total of 521 laypersons completed a 6-month CPR skills assessment and were included in the analysis. Mean age was 51.8±13.7 years, 75% were female, 57% were Caucasian. Overall, mean CC rate was 88.5±25.0 per minute, CC depth was 50.9±2.0 mm, and mean no-flow time was 15.9±2.7 sec/min. CC depth decreased signifi cantly in subjects >62 years (P<0.001). Male subjects performed deeper CCs than female subjects (47.5±1.7 vs. 41.9±0.6, P<0.001). CONCLUSION:We found that layperson age >62 years and female gender are associated with shallower CC depth.

“…Interestingly, no statistical difference with regards to BMI was found when a ratio 15:2 was used and the effect of gender was also less visible. Since 30:2 ratio was viewed to be more exhausting, the physical fitness, exercise habits and fatigue of the individual seem to play significant role in the CPR performance and their role was observed also in other studies [25][26][27]. Russo et al confirmed that the chest compressions performed by female participants are too shallow, however, they also showed that good physical fitness and BMI were found to increase the quality of CPR performance independently of gender [25].…”

INTRODUCTION: Industrial accidents constitute about 20% of all causes of accidents. They are often sudden, unexpected and may lead to tragic consequences, which however can be partially reduced if first aid and emergency treatment are given as soon as possible. The most important part of a chain of survival is the bystanders' response. In practice, it is highly dependent on the ability of co-workers to perform basic first-aid tasks. The aim of this paper was to present the effectiveness of 'practice while watching' training method for the first aid training of the chemical industry employees. The authors focused on the most important elements of the training, which have an impact on the acquisition of knowledge and skills of first aid. MATERIAL AND METHODS: The training involved 69 employees of the chemical industry. The test sheets were used for the assessment, where each of the action steps was assigned points 0 for incorrect and 1 for a properly performed activity. RESULTS: Each step was completed by at least 76% of workers. When providing both adult and infant CPR, the main difficulty was calling for help. Younger employees obtained better results than older colleagues. CONCLUSIONS: The study demonstrated the high effectiveness of the 'practice while watching' method. In addition, workers' age turned out to be a significant variable which affected their performance.
