本实验检验了局限于一个反射发生区的不同压力对另一个反射发生区的压力变化反应的影响。将狗用氯醛糖(100mg/kg)麻醉,并进行人工呼吸。人工控制左室的收缩压和颈动脉窦压,即将一个套管固定在升主动脉内,并连接到一个控制左心室收缩压的压力容器。左心房压是通过把血液转移到左心房和主动脉容器之间的任何方向来控制的。将一侧后肢血管分离,用恒定血流独立地灌注隔离的后肢血管。在7条狗身上,将颈动脉窦压控制在65±2.7或243±4.7mmHg时,左心室收缩压从95±7.2mmHg升至
This experiment examined the effect of different pressures confined to one reflection zone on the pressure response of another zone. Dogs were anesthetized with chloralose (100 mg / kg) and resuscitated. Artificial control of left ventricular systolic pressure and carotid sinus pressure, that is, a cannula in the ascending aorta, and connected to a control of left ventricular systolic pressure vessels. Left atrial pressure is controlled by transferring blood to any direction between the left atrium and the aortic vessel. One side of the hindlimb blood vessels were separated, and the isolated hind limbs were perfused with constant blood flow. In 7 dogs, when the carotid sinus pressure was controlled at 65 ± 2.7 or 243 ± 4.7 mmHg, the systolic pressure of the left ventricle rose from 95 ± 7.2 mmHg
