The haemodynamic responses associated with inflation of the antigravity suit (G suit, aviation type) to 8.0 kPa were studied in a series of 40 patients who underwent neurosurgical operations in the sitting position. The study showed statistically significant increases in systolic arterial pressure (p less than 0.005) and mean central venous pressure (p less than 0.001) with inflation of the suit. The systolic arterial and mean central venous pressures remained significantly elevated immediately before deflation of the suit at the end of the operation (p less than 0.001 and p less than 0.005 respectively). The addition of 0.8-1.0 kPa positive end expiratory pressure during suit inflation was also investigated. A further increase in central venous pressure occurred but this did not achieve statistical significance.
对40例接受坐位神经外科手术的患者进行了一系列研究，以探讨抗重力服（航空型G服）充气至8.0 kPa时的血流动力学反应。研究表明，随着抗重力服充气，收缩压（p<0.005）和中心静脉压平均值（p<0.001）有统计学意义的升高。在手术结束抗重力服放气前，收缩压和中心静脉压平均值仍显著升高（分别为p<0.001和p<0.005）。还研究了在抗重力服充气时增加0.8 - 1.0 kPa呼气末正压的情况。中心静脉压进一步升高，但未达到统计学意义。
