Final answer:
Chest compression fraction (CCF) refers to the percentage of time chest compressions are given during cardiopulmonary resuscitation (CPR) relative to the total duration of the CPR event.
Step-by-step explanation:
Chest compression fraction (CCF) is a key component of cardiopulmonary resuscitation (CPR), which is an emergency technique used when the heart stops beating. It measures the proportion of time during which chest compressions are performed in relation to the total duration of the CPR event. The current standards for high-quality CPR recommend chest compressions of at least 5 cm deep at a rate of 100 compressions per minute. The rhythm of these compressions is comparable to the beat of the song 'Staying Alive' by the Bee Gees. It is vital for maintaining blood circulation, especially to the brain, to prevent irreversible damage and death of neurons that can occur within minutes due to lost blood flow. CPR, including chest compressions, is typically administered until the patient exhibits spontaneous heart contractions or is declared deceased by a healthcare professional.
