A组采用改良的右心导管测定法测定肺动脉平均压、右心室收缩压、右心室舒张压。
The MPAP, RVSP, RVDP were determined by modified rig ht heart catheterization in group A.
记录肺动脉压力波，计算肺动脉平均压。
The pulmonary artery pressure wave was recorded, average pulmonary artery pressure was calculated.
结果老年与非老年患者血浆心钠素浓度、肺动脉平均压及血气参数差异无显著性。
Results There was no significant difference in plasma ANP level, pulmonary artery mean pressure(PAMP) and blood gas parameters between the aged and non-aged patients with COPD.
