A randomized trial on elderly laypersons' CPR performance in a realistic cardiac arrest simulation.

Area of Science:

• Emergency Medicine
• Gerontology
• Cardiopulmonary Resuscitation Research

Background:

• Bystander cardiopulmonary resuscitation (CPR) is crucial for survival following cardiac arrest.
• Previous research suggests elderly lay rescuers may perform CPR less effectively in simulated emergencies.

Purpose of the Study:

• To compare CPR performance in elderly lay rescuers between a realistic cardiac arrest simulation and a traditional testing environment.
• To evaluate the impact of simulation realism on CPR quality, including compression depth, rate, ventilation, and hands-off time.

Main Methods:

• Sixty-four lay rescuers aged 50-75 were randomized to either a realistic or traditional CPR test.
• Both groups performed 10 minutes of telephone-assisted CPR on a manikin.
• The realistic simulation occurred in a confined, noisy apartment without warning, while the traditional test was in a calm classroom setting.

Main Results:

• No significant differences in CPR quality (compression depth, rate, ventilation rate, hands-off time) were observed between the realistic and traditional groups.
• No significant differences in workload or self-reported exhaustion were found between the two simulation environments.
• While chest compression quality was acceptable, ventilation and hands-off times were inadequate in both groups.

Conclusions:

• Elderly lay rescuers can perform chest compressions of acceptable quality for ten minutes in a realistic cardiac arrest simulation.
• Ventilation quality and hands-off time remain areas for improvement for elderly lay rescuers, regardless of the simulation setting.
• Realistic simulations do not appear to negatively impact CPR performance in this demographic.
