Golden time for cardiac arrest patients, it depends on AEDhands off time The golden time to increase the survival rate of patients with acute cardiac arrest is 4 minutes.Whenever first aid is delayed by 1 minute after cardiac arrest, the patients survival rate decreases by 7-10%, but if CPR and the use of anAutomated External Defibrillator (AED) within 4 minutes, the survival rate is increased to 80%. I can. Such cardiac arrest patients can save their precious lives by performing CPR and AED during Golden Time. However, at present, it is not easy to expect a “four minute miracle” to save the hearts of cardiac arrest patients.* Source: Medical Times http://www.medicaltimes.com/News/11129841.
