What is the goal for chest compression fraction (CCF) to promote optimal outcomes?

The goal for chest compression fraction (CCF) is to achieve 80% or higher during cardiopulmonary resuscitation (CPR). CCF measures the percentage of time that effective chest compressions are being administered during the entire resuscitation effort. A higher CCF indicates that there are fewer interruptions in compressions, which is critical for maintaining blood circulation to the vital organs, particularly the heart and brain.

During CPR, every second counts, and minimizing pauses between compressions is essential. When CCF is maintained at 80% or more, studies have shown improved survival rates and better neurological outcomes for patients who experience cardiac arrest. A sustained high CCF helps ensure that the blood flow generated by chest compressions remains effective, thereby enhancing the chances of a successful return of spontaneous circulation (ROSC).

Lower CCF values, such as 50%, 60%, or even 70%, indicate a higher frequency of interruptions or delays in compressions, which could compromise the effectiveness of the resuscitation effort and negatively impact patient outcomes.
