方法受试者在倾斜台上快速倾斜至60度抬头位置后记录动脉血压的变化。在这个位置，受试者的脚由脚踏板支撑。使用插入肘前窝的肱动脉的薄壁 21 号针进行动脉内压测量。针通过尼龙管（内径 0-8 毫米）连接到 Devices 压力传感器和放大器，该系统给出大约 40 cps 的总体频率响应。患者还需要通过向压力计吹气来执行 Valsalva 动作，吹气压力为 40 毫米汞柱，保持 12 至 15 秒，以确定作为对脉压急剧降低的反应，有效的反射性血管舒缩活动发生的速度有多快。 （夏皮-谢弗，1953）。
MethodThe changes in intra-arterial blood-pressure were recorded following rapid tilting of the subjects to a 60 degree head-up position on a tilt table. In this position the subjects' feet were supported by a foot-plate. Intra-arterial pressure measurements were made using a thin-walled 21-gauge needle inserted into the bracbial artery in the antecubital fossa. The needle was connected by nylon tubing (internal diameter 0-8 mm) to a Devices pressure transducer and amplifier, the system giving an approximate over-all frequency response of 40 cpsThe patients were also required to perform a Valsalva manoeuvre by blowing into a pressure gauge with a blow-pressure of 40 mmHg maintained for 12 to 15 seconds, in order to determine how rapidly effective reflex vasomotor activity occurred as a response to an acute reduction of pulse pressure (Sharpey-Schafer, 1953).
