OBJECTIVE: We sought to determine whether a critical cardiac output and oxygen delivery exist in normal pregnancy. We also sought to determine the role of fetoplacental oxygen demand on maternal oxygen transport variables in response to decreased mat

Objective: The hypothesis of our study was that both the systemic and uteroplacental circulations would adapt to chronic maternal anemia to ensure that oxygen supply to maternal tissues would be adequate. Study Design: We measured cardiac output and

The increased circulatory and metabolic demands of pregnancy lead to a variety of adaptive responses in many regional vascular beds. The concomitant development of anemia could modify these adaptive processes. The purpose of our studies was to quanti

We previously observed young lambs to be more tolerant of hypoxia; compared with older lambs, they accumulate lactate at a slower rate during comparable reduction in cardiac output, and have a greater percent decrease in cardiac output before onset o

Accurate assessment of gestational age and fetal weight in the pregnant ewe is important in both acute and longitudinal perinatal studies. We describe two morphometric methods based on the length of the fetal metatarsal bone. These measurements can b

We chronically catheterized 15 newborn lambs (9.5 +/- 2.8 days) and measured the distribution of cardiac output by the radionuclide-microsphere technique at hematocrits ranging from 10 volumes % to 55 volumes %. Seven animals were made progressively

We identified the effects of reductions in arterial blood oxygen concentration from 15.0 to 4.0 ml O2/dl blood on hepatic blood flow, oxygen delivery, oxygen consumption and oxygen extraction in nine chronically catheterized lambs, 9 +/- 1 (SD) days

To determine whether the high oxygen affinity of fetal blood, compared with that of the adult, is advantageous to the fetus during fetal anemia we studied 16 chronically catheterized fetal lambs. Half of the lambs had hemoglobin-oxygen affinity reduc

In 11 chronically catheterized fetal lambs (123 +/- 6, mean +/- SD, days of gestation; term = 147 days), we measured fetal oxygen delivery and oxygen consumption before and during reductions in umbilical blood flow (Qumb). Qumb was reduced by inflati
