Using the ability to perform CPR as a standard of fitness: a consideration of the influence of aging on the physiological responses of a select group of first aiders performing cardiopulmonary resuscitation

Are they trained? Prevalence, motivations and barriers to CPR training among cohabitants of patients with a coronary disease

“…Indeed, 50 % of the physicians interviewed for a German study deemed the benefits of such CPR training to be limited or even useless, while 50 % were concerned that the close family members were physically incapable of performing CPR, and 40 % were concerned that this would distress the close family members [37]. Such distress is not compatible with studies that have demonstrated rather positive effects of CPR training on anxiety levels [24][25][26] as well as a low risk of ischemia until 65 years of age when training has taken place [38].…”

Individualized rescuer change by a team leader during uninterrupted cardiopulmonary resuscitation: comparison with rescuer change in 2-min intervals

“…The most controversial issue is the onset time of rescuer fatigue, which inevitably results in marked deterioration of chest compression quality, especially of compression depth. Some studies reported a significant decrease in compression depth within 1 min from starting CPR [4,7,10], whereas other studies reported no marked decline in compression quality until 2 min [3,14]. Although the 2005 CPR guidelines considered the possibility of early rescuer fatigue, the 2005 CPR guidelines placed more emphasis on the possible benefit of minimal interruption and therefore recommended the RC2 method [8].…”

Maximising CPR utility through biomedical-engineering

“…Investigations of rescuer capacity to keep up compelling mid-section pressure rate and profundity after some time have focused on muscle and/or metabolic exhaustion as a key element in execution deterioration [7] The work interest of CPR is portrayed as humble to difficult, requiring somewhere around 60% and 65% of most extreme achievable workload, [8,9] and similar to a moderate oxygen consuming activity [10] requiring around 4 metabolic equivalents [11]. People's subjective judgments assess CPR as light work and light to some degree hard work [8].…”

“…People's subjective judgments assess CPR as light work and light to some degree hard work [8]. People who are physically fit can perform CPR in the preparation setting for more time frames than can the individuals who are not fit but rather there are no distinctions in the pressure rate or profundity connected with fitness [11].…”
