Without special treatment after circulation is restarted, full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare. [6] [7] Usually brain damage or later brain death results after longer intervals of clinical death even if the heart is restarted and blood circulation is successfully restored ...
Medics were able to establish a faint pulse after eight minutes of CPR. Her heart stopped twice after arriving at the hospital and she was placed on life support. Doctors attempted to lower her body temperature to prevent additional brain injury. She was declared clinically dead for 17 hours after doctors failed to detect brain activity.
Cardiac arrest (also known as sudden cardiac arrest [SCA] [11]) is when the heart suddenly and unexpectedly stops beating. [12] [1] When the heart stops beating, blood cannot properly circulate around the body and the blood flow to the brain and other organs is decreased.

After pulling recent large, long-term, well-designed studies from databases and analyzing them, researchers found that three heart conditions may influence brain health, including cognitive ...
After surgery is completed during the period of cold circulatory arrest, these steps are reversed. The brain and heart naturally resume activity as warming proceeds. The first activity of the warming heart is sometimes ventricular fibrillation requiring cardioversion to re-establish a normal beating rhythm. [42]
DENVER — The family of a 4-year-old boy whose heart had stopped beating hours earlier gathered at Children’s Hospital Colorado last month to say their final goodbyes to Cartier McDaniel.
CPR is likely to be effective only if commenced within 6 minutes after the blood flow stops [160] because permanent brain cell damage occurs when fresh blood infuses the cells after that time, since the cells of the brain become dormant in as little as 4–6 minutes in an oxygen deprived environment and, therefore, cannot survive the ...
