Description
Michael Veldeman and five co-authors study how the brain guards its blood flow in the first hour after a bleed around the brain. In health, the brain holds flow steady as pressure shifts; after such a bleed, that guard may fail. The team re-read data from rats in which a vessel was pierced to mimic the bleed. They tracked blood pressure, skull pressure, and blood flow on both sides of the brain.
On average, the guard held in the first hour. Still, time spent past a danger line rose after the bleed and rose with skull pressure. Two ways of scoring the guard often disagreed. The paper refines how early failure should be judged.
