Cardiopulmonary measurements were determined in 19 nonanesthetized, normal ponies. Mean values for arterial pressure, pulmonary arterial pressure, cardiac output, heart rate, packed cell volume, and hemoglobin are reported, as well as acid-base determinations of arterial blood and cerebrospinal fluid. Respiratory function test data include total ventilation, respiratory rate, alveolar ventilation, oxygen uptake, and carbon dioxide output. The data compare favorably with the available data from previous reports on ponies. Because of large day-to-day variations in total ventilation, alveolar ventilation should be measured if ponies are used in the study of pulmonary function.
对19匹未麻醉的正常小马进行了心肺测量。报告了动脉压、肺动脉压、心输出量、心率、红细胞压积和血红蛋白的平均值，以及动脉血和脑脊液的酸碱测定结果。呼吸功能测试数据包括总通气量、呼吸频率、肺泡通气量、氧摄取量和二氧化碳排出量。这些数据与先前关于小马的报告中的现有数据相比具有优势。由于总通气量存在较大的每日变化，如果在肺功能研究中使用小马，应测量肺泡通气量。
