hypothermic circulatory arrest

Hypothermic circulatory arrest is a medical procedure where doctors cool the body significantly to reduce its need for oxygen, allowing them to temporarily stop blood circulation during complex surgeries. This technique helps protect the brain and other vital organs while surgeons work on difficult parts of the heart or blood vessels. By lowering the body's temperature, metabolism slows, making it safer to pause circulation for a short period without causing damage. Once the procedure is complete, normal blood flow and body temperature are carefully restored.
