自从发现猫吸入低氧混合气体能引起肺动脉压升高以来,许多作者证实多种哺乳类动物在吸入低氧混合气体、放于低压舱持续减压或送进高原均可引起肺动脉压升高。Hultgren)观察了七种高原动物的心脏,都有不同程度的右室肥大。有关高原动物肺动脉压、血气和右室大小,国内尚未见到报导,研究这些变化,对于探讨高原适应和高原心脏病 Since the discovery that cats inhaled hypoxic airways can cause pulmonary arterial pressure to rise, many authors have shown that various mammalian species can cause elevated pulmonary arterial pressure by inhaling hypoxia mixed with air and continuously depressurizing them in the hypoblast or sending them to the plateau. Hultgren) observed the hearts of seven plateau animals, all with varying degrees of right ventricular hypertrophy. On the plateau animal pulmonary arterial pressure, blood gas and right ventricular size, has not been reported in the country to study these changes, to explore the plateau adaptation and altitude heart disease
