High-quality cardiopulmonary resuscitation (CPR) chest compressions require attention to rate and depth. Fatigue impacts compression quality, with gender-based differences observed in performance and fatigue resistance during CPR training.
Area of Science:
- Emergency Medicine
- Cardiology
- Resuscitation Science
Background:
- Cardiopulmonary resuscitation (CPR) is a critical intervention for cardiopulmonary arrest.
- Current guidelines emphasize optimal chest compression depth and rate.
- Understanding chest compression quality indicators is vital for effective CPR training.
Purpose of the Study:
- To investigate the interrelationships among chest compression quality indicators.
- To identify key factors influencing chest compression performance in CPR training.
- To explore the impact of fatigue on CPR quality.
Main Methods:
- 219 healthcare workers underwent CPR training using a Laerdal ACLS model.
- Chest compression quality metrics (hand placement, rate, depth, recoil) and self-reported fatigue were monitored.
- Data were collected using the Laerdal Computer Skills and Reporting System.
Main Results:
- Male participants generally exhibited higher self-reported fatigue times and accuracy in compression depth and rate compared to females.
- Females demonstrated higher accuracy in chest wall recoil.
- Self-reported fatigue correlated with most quality indexes, except compression rate.
Conclusions:
- Regular CPR training is essential for maintaining proficiency.
- Strategies to mitigate fatigue, such as practitioner rotation, are recommended, particularly for female or less experienced individuals.
- Focusing on compression rate control in training can delay fatigue, ensure adequate depth, and enhance overall CPR quality.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
