CARDIOPULMONARY MEASUREMENTS IN NONANESTHETIZED, RESTING NORMAL PONIES

Abstract

[Because of the need for more complete documentation of control data on the nonanesthetized pony, data for 37 variables from 19 ponies was collected.] Mean values for arterial pressure, pulmonary arterial pressure, cardiac output, heart rate, packed cell volume and Hb 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, O2 uptake and CO2 output. 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.
