雌性山羊8只。平原运动时的肺动脉平均压(PPa)由平原静息时的15.6±1.4增高8.0±3.9mmHg(P<0.05)。模似400m高原即刻静息时的PPa为23.1±0.8mmHg,与原静息比较相差显著(P<0.05)。模似4000m高原即刻运动,高原停留90分钟脉息时和动时的PPa分别为22.1±1.2、22.0±1.0和21.2±0.7mmHg,三者与平原静息时的PPa比
8 female goats Mean pulmonary artery pressure during plain exercise (PPa) increased by 8.0 ± 3.9 mm Hg (P <0.05) from 15.6 ± 1.4 at rest at plain. The PPa immediately after resting at 400m plateau was 23.1 ± 0.8mmHg, which was significantly different from the original resting (P <0.05). The simulated 4000-m plateau movement immediately, plateau dwell 90 minutes pulse time and dynamic PPa were 22.1 ± 1.2, 22.0 ± 1.0 and 21.2 ± 0.7mmHg, the three and plain resting PPa ratio
