Примери за hypoxia

• 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.

• Also, gas exchange is affected, with a reduced awareness of the response to hypoxia and hypercapnia as described later.

• Relative hypoxia is a potent vasodilator in the coronary, cerebral, and adrenal beds, but a vasoconstrictor in the pulmonary bed.

• In mammals, nitric oxide stimulates increased blood flow to areas where hypoxia occurs.

• This exacerbates hypoxia, which can promote tumour angiogenesis by enhancing the production of proangiogenic factors.

• End-stage hypoxia in this condition is manifest by a score of either 2/10 or 0/10.

• In contrast, the effects of striatal injuries are evident in childhood, and the caudate is highly vulnerable to hypoxia and ischemia.

• This process, in addition to sustained or episodic hypotension may induce cerebral hypoperfusion, ischaemia and hypoxia.
