Lay person use of automatic external defibrillation

Area of Science:

• Cardiology
• Emergency Medicine
• Medical Education

Background:

• Sudden cardiac arrest (SCA) survival rates are significantly impacted by rapid defibrillation.
• Automatic external defibrillators (AEDs) offer a potential solution for early intervention by lay rescuers.
• Assessing lay person proficiency in AED use is crucial for public health initiatives.

Purpose of the Study:

• To evaluate the capability of lay persons to acquire and maintain proficiency in using an automatic external defibrillator (AED).
• To determine the effectiveness of lay rescuer-administered defibrillation in simulated cardiac arrest scenarios.

Main Methods:

• Thirty-four family members of cardiac arrest survivors received training in CPR and AED use.
• Skill performance was assessed immediately post-training and at six-week and three-month follow-up intervals.
• Performance metrics included speed and quality of cardiopulmonary resuscitation (CPR) cycles and defibrillatory shock delivery.

Main Results:

• The majority of participants (32/34) successfully completed CPR and AED protocols within an average of four minutes.
• Initial training resulted in an average first shock delivery time of two minutes.
• Performance showed statistically significant decrements in speed and quality at follow-up assessments (P < .01).

Conclusions:

• Lay persons can be trained to safely and effectively operate AEDs.
• Trained lay rescuers can deliver defibrillatory shocks significantly faster than typical emergency medical technician response times.
• Home placement of AEDs for high-risk cardiac arrest patients is a viable strategy to improve survival outcomes.
