Circulatory responses to prolonged hypoxemia in fetal sheep.
TL;DR: It is demonstrated that the sheep fetus is able to maintain the normal protective circulatory adjustments seen with acute hypoxemia for up to 48 hours in the absence of progressive metabolic acidemia.

Fetal and maternal endocrine responses to prolonged reductions in uterine blood flow in pregnant sheep
TL;DR: It is concluded that fetal hypoxemia-acidemia after restriction of uterine blood flow provokes fetal adrenocorticotropic hormone release, but the elevation in cortisol is not sustained, and the level of fetal cortisol rises progressively, consistent with fetal adrenal activation.

Oxygen consumption is maintained in fetal sheep during prolonged hypoxaemia.
TL;DR: Experiments were conducted in 12 chronically-catheterized pregnant sheep to examine the effect of prolonged hypoxaemia secondary to the restriction of uterine blood flow on fetal oxygen consumption and overall oxygen consumption by the fetus.

Cardiovascular and metabolic responses to intermittent umbilical cord occlusion in the preterm ovine fetus.
TL;DR: The increase in lactate and reduced high-FHR variation episodes over successive umbilical cord occlusions may affect fetal growth and development, suggesting an altered chemoreflex response.

Circulatory Responses to Prolonged Hypoxemia in Fetal Sheep
TL;DR: It is demonstrated that the sheep fetus is able to maintain the normal protective circulatory adjustments seen with acute hypoxemia for up to 48 hours in the absence of progressive metabolic acidemia.
