肺血流(PBF)分布主要由重力(g)决定的观点被接受已三十多年了。肺血流分布资料的解释已用于由Hughes、West等制作的四区域模型中。最近,收集了值得重视的资料表明重力对四足动物的肺血流分布的影响很小。在本研究中,用增加重力Gx作为变量研究了重力g的作用。在布鲁克斯空军基地阿姆斯特朗试验室,在离心机上把没有麻醉的猪暴露于-Gx(背侧到腹侧的惯性力)环境中,用荧光微粒测试肺血流分布。动
The distribution of pulmonary blood flow (PBF) has been accepted for more than three decades mainly from the point of view of gravity (g). The interpretation of pulmonary blood flow distribution data has been used in a four-region model made by Hughes, West et al. Recently, valuable information has been collected to show that gravity has little effect on pulmonary blood flow distribution in quadrupedal animals. In this study, the effect of gravitational g was studied with the addition of gravity Gx as a variable. The non-anesthetized pigs were exposed to a Gx (dorsal to ventral inertial force) environment on a centrifuge at the Armstrong Laboratory at Brooks AFB to test the pulmonary blood flow distribution with fluorescent microparticles. move
