A video showing an intensivist performing cardiopulmonary resuscitation (CPR) for nearly 30 minutes inside an intensive care unit (ICU) has gone viral, sparking emotional and medical debate online.

The clip captures the doctor continuing chest compressions with sustained effort and focus. According to the post accompanying the video, the patient was eventually revived.

What happens during cardiac arrest?

Cardiac arrest occurs when the heart suddenly stops pumping effectively, cutting off blood supply to vital organs. Brain injury can begin within four to six minutes without oxygen.

CPR is performed to manually maintain blood circulation through chest compressions. In hospital settings, it is combined with defibrillation, oxygen support, emergency medications such as adrenaline and advanced life support protocols. The aim is to achieve “return of spontaneous circulation” (ROSC).

Is survival after 30 minutes possible?

Medical experts say survival after prolonged CPR is possible, particularly in hospital environments where intervention is immediate.

While survival chances decrease over time, outcomes depend on several factors: the cause of cardiac arrest, how quickly CPR began, the patient’s overall health, and whether the heart rhythm is shockable.

In certain reversible conditions — such as specific rhythm disturbances, drug reactions or hypothermia — resuscitation efforts may continue for 40 to 60 minutes if recovery appears feasible.

Why ICU settings matter

In an ICU, patients are continuously monitored, allowing cardiac arrest to be detected instantly. Medical teams can intubate promptly, administer targeted medication and use advanced equipment without delay.

Though prolonged CPR is not routine, it is not unheard of in critical care. Experts emphasise that decisions about continuing or stopping resuscitation are made based on established medical guidelines and patient response.

The viral video highlights both the physical endurance required of medical professionals and the importance of timely, protocol-driven care. While some have termed it a “miracle,” doctors note that such recoveries are often the result of rapid response, teamwork and sustained effort.
