The cardiopulmonary effects of dorsal recumbency were studied in awake cows restrained for surgical correction of left displaced abomasum. During the recumbent period, PaO2, PaCO2, arterial pH, and base excess values were significantly decreased. Heart rate, respiratory rate, blood hemoglobin concentrations, and rectal temperature increased significantly.
对清醒的、因左方变位皱胃需手术矫正而受到限制的奶牛，研究了背卧位对心肺的影响。在卧位期间，动脉血氧分压（PaO2）、动脉血二氧化碳分压（PaCO2）、动脉血pH值和碱剩余值显著降低。心率、呼吸频率、血液血红蛋白浓度和直肠温度显著升高。
