0 a condition in which there is not enough oxygen available to the blood and body tissues:
Hypoxia can result in an increase in the production of erythropoietin.
For example, pre-adaptation to cold may protect against subsequent exposure to ionizing radiation (positive acclimation), but may increase vulnerability to hypoxia (negative acclimation).
Although vasodilatation may improve peripheral blood flow, it may also cause shunting which can result in regional tissue hypoxia.
These results indicate that at least in the acute situation hypoxia alone does not generate the markers of oxidative stress that typify the preeclamptic placenta.
The cave's entrance became buried, and inadequate ventilation caused an episode of hypoxia and carbon monoxide poisoning.
Five infants had hypoxia <40 torr and 5 needed a continuous infusion of epinephrine >1 ng/kg/min.
Five infants had hypoxia <40 torr and 5 needed a continuous infusion of epinephrine >1 tig/kg/min.
Right ventricular dysfunction has been attributed either to persisting high right ventricular afterload or to chronic myocardial hypoxia prior to repair.
Factors that promote cellular dehydration, tissue hypoxia, and leukocyte or endothelial cell activation are all involved in generating vaso-occlusion.
