Deep hypothermia reduces cellular metabolism and protects tissues from ischaemia during circulatory arrest, … Deep hypothermic circulatory arrest (DHCA) is a surgical technique that induces deep medical hypothermia. It involves cooling the body to temperatures between 20 °C (68 °F) to 25 °C (77 °F), and stopping blood circulation and brain function 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 surgery on large blood vessels that lead to or from the brain. DHCA is used to provide a bette…

WebJan 26, 2024 · Cardiopulmonary arrest (CPA) is the cessation of effective ventilation and circulation. It is also known as cardiac arrest or circulatory arrest. In adults, it is most likely to be caused by a primary cardiac event. The most common electrical mechanism which is responsible for 50 to 80% of cardiopulmonary arrest is ventricular fibrillation (VF). Webcirculatory arrest: 1. cessation of the circulation of blood as a result of ventricular standstill or fibrillation. 2. intentional cessation of circulation by temporarily stopping cardiopulmonary bypass flow during certain thoracic aortic operations; used with intentional profound total-body hypothermia to protect vital organs. diaper covers patterns free
