How much is golden time in CPR?

In CPR, the "golden time" refers to the critical period immediately following cardiac arrest during which prompt intervention and effective cardiopulmonary resuscitation (CPR) can significantly improve the chances of survival and minimize brain damage. This timeframe is often considered to be the first few minutes, typically up to about 4-6 minutes, after the heart stops beating.

During the golden time, the brain and other vital organs are still viable and can withstand a temporary lack of oxygen. By initiating CPR as soon as possible, rescuers can help maintain blood circulation and oxygen delivery to the brain and other organs, thus preserving vital functions and increasing the likelihood of a successful resuscitation.

For effective CPR during the golden time, it's crucial to quickly:

1. Check for responsiveness and ensure airway patency (open airway).

2. Provide initial rescue breaths to deliver oxygen (if trained and comfortable).

3. Start chest compressions at a rate of at least 100-120 compressions per minute while allowing full chest recoil after each compression.

4. Continue CPR and alternate between chest compressions and rescue breaths (if trained) until professional medical help arrives or the person shows signs of life.

The golden time emphasizes the importance of acting swiftly and taking immediate action after a cardiac arrest. By starting CPR within this critical time window, bystanders can greatly improve the chances of a positive outcome and increase the person's likelihood of survival with minimal neurological damage.
