| 摘 要： | 观察了8只雌性山羊在急性缺氧(模拟4000m高原)条件下运动时心肺血流动力学的改变。急性缺氧可致肺动脉压升高,心率增加,心输出量和体动脉压无明显变化。平原运动时,肺动脉压、心输出量和心率均有明显增加。但在急性缺氧条件下运动时,肺动脉压并来进一步升高,其原因可能与急性缺氧条件下山羊的pHa升高有关。

| Abstract: | The effects of physical activity on cardiopulmonary hemodynamics under acute hypoxia at a simulated altitude of 4000 meters were studied in 8 conscious goats. It is known that acute hypoxia alone can result in an elevation of pulmonary arterial pressure and acceleration of heart rate, but no obvious effects on cardiac output and systemic arterial pressure, and physical activity can increase the pulmonary arterial pressure, cardiac output and heart rate at sea level. It was found that a combination of physical activity and a simulated altitude of 4000m could bring about a more marked increase of cardiac output and heart rate but no further increase of pulmonary arterial pressure. The latter phenomenon might be due to increased alkalinity of the arterial blood underhypoxic condition. |
