How much of the time should the chest compression fraction (CCF) aim for in CPR?

The chest compression fraction (CCF) is a crucial metric in cardiopulmonary resuscitation (CPR) that gauges the proportion of time during a resuscitation attempt when effective chest compressions are being administered. Ideally, a high CCF indicates that compressions are being performed consistently without unnecessary interruptions.

Aiming for a CCF of 60-80% is supported by guidelines from organizations such as the American Heart Association. This range allows for sufficient time to perform chest compressions effectively while also permitting necessary interruptions for critical interventions, such as defibrillation or rescue breaths, when indicated.

Maintaining a CCF within this range ensures optimal blood flow to vital organs during CPR, enhancing the likelihood of a successful outcome. A CCF lower than this could mean that the quality of CPR is compromised, reducing the chances of survival and recovery for the patient.
