Survival chance 22% if CPR given in a minute: Study

A person who is administered CPR within a minute of cardiac arrest has 22% chance of survival, while one who gets it after 39 minutes has only 1% probability, shows a new study. It also shows that a longer resuscitation period may not necessarily be more beneficial.

CPR involves chest compressions and mouth-to-mouth breathing at a ratio of 30:2 compressions-to-breaths. Previous studies have shown that a longer resuscitation time for patients with in-hospital cardiac arrest is linked to lower odds of survival, but experts have been unable to make specific recommendations on when to stop the procedure. To address this knowledge gap, researchers measured the effect of CPR duration (in minutes) on outcomes for over 3.5 lakh US adults (average age 67 years) who had an in-hospital cardiac arrest between 2000 and 2021.

According to the BMJ, after accounting for potentially influential factors such as age, sex, ethnicity, and a range of pre-existing conditions, the results showed that of the 3,48,996 patients, 233,551 (67%) achieved return of spontaneous circulation with an average CPR duration of 7 minutes, whereas 115,445 (33%) did not achieve return of spontaneous circulation with an average CPR duration of 20 minutes.

At one minute’s CPR duration, the probabilities of survival and favorable functional outcome among patients were 22% and 15%, respectively, BMJ stated. Mohit Gupta, professor of cardiology at G B Pant hospital, said the study highlights the need to train people to perform CPR.

CPR within a minute of cardiac arrest increases the chance of survival to 22%.
