How is the Cardiac Compression Fraction (CCF) calculated during a code?

The Cardiac Compression Fraction (CCF) is an important metric used to evaluate the effectiveness of cardiopulmonary resuscitation (CPR) during a code. It provides insight into how much of the total resuscitation time is actually spent delivering chest compressions.

Calculating CCF involves taking the actual time spent delivering chest compressions and dividing it by the total duration of the code. This ratio is expressed as a percentage, reflecting the proportion of the entire resuscitation effort that contributes to blood flow generated by chest compressions. A higher CCF indicates more efficient CPR, as it suggests that rescuers are minimizing interruptions in compressions, which is crucial for maintaining circulation and increasing the chances of a successful resuscitation.

The other choices relate to aspects of CPR measurement but do not accurately define how CCF is calculated in terms of the specific time metrics needed for this crucial ratio. Understanding the correct method to assess CCF helps in improving CPR practices and outcomes during emergency resuscitation efforts.
