The effects of pneumatic antishock trousers on central venous pressure (CVP) and mean arterial pressure (MAP) were compared with those of volume expansion with normal saline in a group of healthy young men. CVP increased from 4.8 +/- 1.9 to 7.3 +/- 2.5 mm Hg (P less than .001) with the suit and from 4.7 +/- 1.9 to 7.3 +/- 2.2 mm Hg (P less than .001) with volume expansion. During suit use, MAP increased from 85 +/- 6.7 to 93 +/- 6.8 mm Hg (P less than .001), while during volume expansion it did not change. Therefore, despite equivalent increases in CVP, the pneumatic antishock suit significantly increased MAP while volume expansion did not. The data suggest that the increased blood pressure produced by the suit may be at least in part dependent on mechanisms other than increased preload from an "auto transfusion" of blood into the central circulation.
在一组健康年轻男性中，对比了气动抗休克裤对中心静脉压（CVP）和平均动脉压（MAP）的影响与用生理盐水扩容的影响。使用该裤子时，CVP从4.8±1.9毫米汞柱升至7.3±2.5毫米汞柱（P＜0.001），扩容时CVP从4.7±1.9毫米汞柱升至7.3±2.2毫米汞柱（P＜0.001）。使用裤子期间，MAP从85±6.7毫米汞柱升至93±6.8毫米汞柱（P＜0.001），而扩容期间MAP未改变。因此，尽管CVP升高程度相当，但气动抗休克裤显著提高了MAP，而扩容则未起到这一作用。数据表明，该裤子产生的血压升高可能至少部分依赖于除血液“自身输血”进入中心循环导致前负荷增加之外的其他机制。
