据报道,在肺动脉高压症患者的肺功能中,可有动脉血氧分压(Pao_2)和弥散功能(%DLco)降低。作者对肺纤维症(PF)与慢性肺气肿(CPE)引起的继发性肺动脉高压症患者的肺功能与右肺下动脉最大横径(RDPAD)(图)的关系进行了探讨。
It has been reported that pulmonary function in patients with pulmonary hypertension may have decreased PaO_2 and diffuse function (% DLco). The authors investigated the relationship between pulmonary function and the maximum transverse diameter of the right pulmonary artery (RDPAD) in patients with secondary pulmonary hypertension due to pulmonary fibrosis (PF) and chronic emphysema (CPE) (Figure).
