The fetal cardiovascular response to acute hypoxemia consists of a decrease in heart rate, a
variable change in mean arterial pressure, and an increase in peripheral vascular …

The peripheral arterial chemoreceptor response to hypoxemia in the fetus is predominantly
cardiovascular, invoking a fall in heart rate and a variable change in blood pressure. No …

Fetal cardiovascular response to acute hypoxemia is characterized by bradycardia,
hypertension, and redistribution of cardiac output. The role of aortic and carotid …

1. We studied the effects of acute isocapnic hypoxia on arterial and central venous
pressures, carotid and femoral blood flows and heart rate in intact and carotid denervated …

Effects of chronic hypoxia on chemoreceptors and chemoreflexes in the fetus and neonate
are reviewed. The effects are discussed in relation to those in the adult, in which there is an …

Carotid chemoreceptor activity was detected in each of fourteen halothane or
pentobarbitone anaesthetized exteriorized fetal lambs of 90‐143 days gestational age …

We tested the hypothesis that the llama fetus has a blunted cardiovascular chemoreflex
response to hypoxemia by investigating the effects of acute hypoxemia on perfusion …

Arterial baroreceptors and chemoreceptors were denervated in eight fetal lambs in utero.
Carotid sinus and carotid body denervation was accomplished by stripping the carotid artery …

1. In foetal lambs the effect of raising and lowering arterial PO2 (by varying the O2 content of
the maternal inspired gas mixture) was studied in order to determine whether the systemic …

The fetus mounts a coordinated cardiovascular response to an insult of acute hypoxaemia
which involves neural and endocrine components. During acute hypoxaemia in late …
