acute hypoxia exposure

The index change rates had corresponding changes with the rising of the simulate-altitude, before acute exposure in hypoxia and just acute exposure in hypoxia.

随着模拟海拔高度的升高，在急性低氧暴露前后，这些指标也随之发生相应递增或递减变化。

CONCLUSION: NTG nebulization produces a selective pulmonary vasodilation either during or after the exposure of hypoxia and improves myocardial impairment in acute hypoxic newborn piglets.

结论：缺氧同时或缺氧后雾化吸入NTG均能选择性地降低急性低氧引起的肺动脉高压，对心肌也有一定的保护作用。
