    Description

    Cardiac arrest is when the heart suddenly stops pumping blood around the body. A person whose heart is restarted can have neurological problems (brain injury). This is because the brain does not get enough oxygen during the cardiac arrest.

    In this procedure, after a person's heart is restarted but while they are still in a coma, their body temperature is controlled. Their body is kept to a normal temperature of between 36.5°C and 37.5°C, or it is cooled to between 32°C and 36°C for 1 to 3 days. The aim is to improve survival and reduce the risk of developing neurological problems.
