What chest compression fraction (CCF) value indicates a need for improvement in CPR quality?

A chest compression fraction (CCF) refers to the percentage of time during a resuscitation attempt that effective chest compressions are administered. A CCF of 58% indicates that an inadequate amount of time is being spent performing compressions relative to the overall duration of the resuscitation effort, which is below the recommended threshold of 60%. High-quality CPR aims for a CCF of at least 60% to ensure sufficient blood flow and maximize the chances of survival.

When the CCF is below 60%, it suggests that excessive interruptions may be occurring, perhaps due to factors such as prolonged analyses of the rhythm, intubation attempts, or lack of coordination among the resuscitation team. This reduction in compressions is critical as each second without effective compressions diminishes the chance of achieving a successful outcome.

In contrast, a CCF of 70%, 80%, or even 90% would indicate better performance in maintaining compressions throughout the resuscitation process and would be considered adequate or excellent, thus not signaling a need for improvement. Prioritizing uninterrupted high-quality compressions is essential for enhancing the effectiveness of CPR and ultimately improving patient outcomes.
