Chest compression fraction (CCF) is the cumulative time spent providing chest compressions divided by the total time taken for the entire resuscitation. Targeting a CCF of at least 60% is intended to limit interruptions in compressions and maximize coronary perfusion during resuscitation. 

Airway management is one critical factor in the overall CCF during resuscitation. Having an airway strategy that minimizes interruption of chest compressions while managing and protecting the airway is critical.
