Hypothermic Circulatory Arrest

We all heard of cases, where patients miraculously survived an accident because they were exposed to cold temperatures. They broke through the ice on a lake or got stuck in freezing temperatures outdoors and survived against all odds.
Well, Medical Professionals  have used this phenomenon to their advantage and induce it in their patients on purpose to save them.

 (HCA) is a surgical technique that involves cooling the body of the patient and stopping blood circulation. It is used in cardiac surgery to allow operation procedures without clamping the aorta while keeping the surgical field free of blood and in neurosurgery to repair some brain aneurysms.

The procedure requires keeping the patient in a state of hibernation at 12–18 °C with no breathing, heartbeat, or brain activity for up to one hour. Blood is drained from the body to eliminate blood pressure. The patient is considered clinically dead during the operation. This allows surgeons to perform procedures that would otherwise not be possible, because the patient would bleed to death.
