What is chest compression fraction?

Chest compression fraction refers to the proportion of time during a cardiac arrest that is spent administering chest compressions. It is an important measure of the quality of cardiopulmonary resuscitation (CPR) being delivered during a resuscitation attempt.

The current guidelines recommend a chest compression fraction of at least 60%, meaning that chest compressions should be performed for at least 60% of the total resuscitation time. Research has shown that higher chest compression fractions are associated with improved outcomes for patients in cardiac arrest.

Achieving and maintaining a high chest compression fraction can be challenging, as interruptions in chest compressions are common during CPR for various reasons such as rhythm analysis, defibrillation, or switching rescuers. Rescuers should strive to minimize interruptions and focus on delivering high-quality chest compressions to maximize the chances of successful resuscitation.

Monitoring and measuring chest compression fraction during CPR can help identify areas for improvement in resuscitation practices and training. Regular training and practice are essential for healthcare providers to maintain proficiency in delivering high-quality CPR and achieving optimal chest compression fractions.
