Objective to study the effects of acute hypoxia and intermittent hypoxic acclimatization on cardiac systolic and diastolic functions in rats.
目的研究急性缺氧和慢性适应性缺氧对大鼠心脏收缩和舒张功能的影响。
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。
Conclusion Acute hypoxia can affect cardiac functions and hypoxic acclimatization can alleviate the hypoxic effects on cardiac functions.
结论急性重度缺氧可显著抑制心功能，动物经低氧适应后，心脏功能明显改善，可减轻缺氧对心脏的损伤。
