May support autotransfusion in hypovolemic stress; hypothesis-generating and should not yet change practice.
Does high-level lower body negative pressure induce compensatory absorption of extravascular fluid from skeletal muscle and skin in humans?
Pronounced hypovolaemic circulatory stress induced by LBNP causes rapid transcapillary fluid absorption from skeletal muscle and skin, demonstrating a large potential for 'autotransfusion' to increase plasma volume.
Länne et al. (1989) studied this question.
