Response of local vascular volumes to lower body negative pressure stress.

摘要: The present study involved an intravenous injection of radio-active iodinated serum albumin, equilibration this isotope within the vascular space, and continuous measurement activity over selected anatomical areas before, during following multiple human LBNP tests. Both rate magnitude pooling were distinctly different each five lower body areas. In upper body, all except abdomen showed depletions from their resting volumes LBNP. presence uniquely patterns in apparent stability abdominal volumes, a possible decrease cerebral blood volume represent major findings study.
