The venous occlusion technique was used to measure capillary pressure in the forearm and foot of man over a wide range of venous pressures. In six recumbent subjects venous pressure (Pv) in the forearm (mean +/- SE) was 9.3 +/- 1.4 mmHg and the venous occlusion estimate of capillary pressure (Pc) was 17.0 +/- 1.6 mmHg, whereas in another six subjects Pv in the foot was 17.1 +/- 1.2 mmHg and Pc was 23.4 +/- 2.5 mmHg. Venous pressure in the limbs was increased either by changes in posture or by venous congestion with a sphygmomanometer cuff. On standing Pv in the foot increased to 95.2 +/- 1.5 mmHg and Pc rose to 112.8 +/- 3.1 mmHg. The relationship established between venous pressure and capillary pressure in the forearm is Pc = 1.16 Pv + 8.1, whereas in the foot the relationship is Pc = 1.2 Pv + 1.6. The magnitude and duration of the changes in capillary pressure were also recorded during reactive hyperemia. The venous occlusion method of measuring capillary pressure is simple and easily applied to studies in humans.
采用静脉闭塞技术在较宽的静脉压范围内测量人体前臂和足部的毛细血管压。在6名卧位受试者中，前臂的静脉压（Pv）（均值±标准误）为9.3±1.4 mmHg，毛细血管压（Pc）的静脉闭塞估计值为17.0±1.6 mmHg，而在另外6名受试者中，足部的Pv为17.1±1.2 mmHg，Pc为23.4±2.5 mmHg。通过改变体位或使用血压计袖带造成静脉充血来增加肢体的静脉压。站立时，足部的Pv升至95.2±1.5 mmHg，Pc升至112.8±3.1 mmHg。前臂静脉压与毛细血管压之间建立的关系为Pc = 1.16 Pv + 8.1，而在足部该关系为Pc = 1.2 Pv + 1.6。在反应性充血期间还记录了毛细血管压变化的幅度和持续时间。测量毛细血管压的静脉闭塞方法简单，易于应用于人体研究。
