Deep hypothermic circulatory arrest (DHCA) is a surgical technique in which the temperature of the body falls significantly (between 20 °C (68 °F) to 25 °C (77 °F)) and blood circulation is stopped for up to one hour. It is used when blood circulation to the brain must be stopped because of delicate surgery within the brain, or because of ...
This deliberate temporary induction of clinical death is called circulatory arrest. It is typically performed by lowering body temperature to between 18 °C and 20 °C (64 and 68 °F) and stopping the heart and lungs. This state is called deep hypothermic circulatory arrest.
For example, surgeons already employ a method known as deep hypothermic circulatory arrest (DHCA) in order to stop brain function and circulation for certain types of major surgeries.
EPR uses hypothermia, drugs, and fluids to "buy time" for resuscitative surgery. If successful, EPR may someday be deployed in the field so that paramedics can suspend and preserve patients for transport. EPR is similar to deep hypothermic circulatory arrest (DHCA) in that hypothermia is induced. However, the purposes and procedures of EPR ...
Deep hypothermic circulatory arrest is a medical technique in which the brain is cooled as low as 10 °C, which allows the heart to be stopped and blood pressure to be lowered to zero, for the treatment of aneurysms and other circulatory problems that do not tolerate arterial pressure or blood flow. The time limit for this technique, as also ...
Elevating Ca 2+ concentration to a high enough level results in cardiac arrest in systole. This unfortunate irreversible event is referred to as "stone-heart" or rigor. Hypothermia is the other key component of most cardioplegic strategies. It is employed as another means to further lower myocardial metabolism during periods of ischemia.
Targeted temperature management (TTM), previously known as therapeutic hypothermia or protective hypothermia, is an active treatment that tries to achieve and maintain a specific body temperature in a person for a specific duration of time in an effort to improve health outcomes during recovery after a period of stopped blood flow to the brain.

Givens was hospitalized for hypothermia five times over the last year of his life. “I understand we all have concerns about Mr. Givens' care,” a prison nurse remarked in one email exchange.
