摘要

在84只体重19.0 +/- 3.2 kg (x +/- s)的清醒杂种狗中,发现肺动脉平均压力为14.2 +/- 3.1 mmHg。102只麻醉犬体重19.9 +/- 3.2 kg,肺动脉压14.3 +/- 2.8 mmHg,腹主动脉压121.3 +/- 16.9 mmHg;同时血氧饱和度为91.9 +/- 1.3%。选取87只麻醉犬(体=体重:15 ~ 25kg;Sao2: 90- 94%;平均主动脉压:80-150 mmHg;平均肺动脉压:9-19.5 mmHg)显示肺动脉压与氧饱和度有显著关系。然而,这些压力和动物的体重之间没有明显的关系。平均肺压正常范围下限为8 mmHg,上限为20 mmHg。

Pulmonary arterial pressure in conscious and anaesthetized dogs.

In 84 conscious mongrel dogs weighting 19.0 +/- 3.2 kg (x +/- s), the mean pressure in the pulmonary artery was found to be 14.2 +/- 3.1 mmHg. In 102 anaesthetized dogs weighting 19.9 +/- 3.2 kg, pulmonary arterial pressure was 14.3 +/- 2.8 mmHg and pressure in the abdominal aorta 121.3 +/- 16.9 mmHg ; the O2 saturation in the arterial blood recorded oximetrically at the same time was 91.9 +/- 1.3%. Statistical analysis of the data derived from a selection of 87 of these anaesthetized dogs (body=weight : 15-25 kg ; Sao2 : 90-94 % ; mean aortic pressure : 80-150 mmHg ; mean pulmonary arterial pressure : 9-19.5 mmHg) revealed a significant relation between pulmonary pressure and O2 saturation. No significant relation was demonstrable, however, between these pressures and the animals' body-weight. The lower limit of the normal range of mean pulmonary pressure was 8 mmHg and the upper limit 20 mmHg.
