| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
Oxygen deficiency causing a very strong drive to correct the deficiency
Classified under:
Nouns denoting stable states of affairs
Hypernyms ("hypoxia" is a kind of...):
drive (a physiological state corresponding to a strong need or desire)
Hyponyms (each of the following is a kind of "hypoxia"):
anemic hypoxia (hypoxia resulting from a decreased concentration of hemoglobin)
hypoxic hypoxia (hypoxia resulting from defective oxygenation of the blood in the lungs)
ischemic hypoxia; stagnant hypoxia (hypoxia resulting from slow peripheral circulation (such as follows congestive cardiac failure))
altitude sickness (effects (as nosebleed or nausea) of oxygen deficiency in the blood and tissues at high altitudes)
anoxia (severe hypoxia; absence of oxygen in inspired gases or in arterial blood or in the tissues)
asphyxiation; suffocation (the condition of being deprived of oxygen (as by having breathing stopped))
Holonyms ("hypoxia" is a part of...):
asphyxia (a condition in which insufficient or no oxygen and carbon dioxide are exchanged on a ventilatory basis; caused by choking or drowning or electric shock or poison gas)

This agent may be used as a hypoxia marker for detecting oxygen gradients in living tissues.
(Pimonidazole Hydrochloride, NCI Thesaurus)
Niacinamide acts as a chemo- and radio-sensitizing agent by enhancing tumor blood flow, thereby reducing tumor hypoxia.
(Niacinamide, NCI Thesaurus)
Hypoxia is a potent inducer of VEGF in vitro.

As a vascular disruption agent (VDA), this agent also disrupts tumor neovascularization, which may result in a reduction in tumor blood flow and tumor hypoxia and ischemic necrosis.
(Crolibulin, NCI Thesaurus)
This agent also causes decreased expression of genes involved in tumor hypoxia and angiogenesis.

Recurrent episodes of hypoxia/hypoxemia have long-term detrimental effects on cardiovascular health.
(Central Sleep Apnea Syndrome, NCI Thesaurus)
Progression of anaphylaxis into systemic shock, which is characterized by significant reduction in tissue perfusion which leads to hypoxia and hypotension, and can lead to death if untreated.
(Anaphylactic shock, NCI Thesaurus)
Inhaled carbogen reduces diffusion-limited tumor hypoxia, increasing tumor radiosensitivity due to the increased availability of molecular oxygen for cytotoxic radiation-induced oxygen free radical production.
(Carbogen, NCI Thesaurus)
The extent of (61)Cu-ATSM retention in tissue is inversely related to the state of tissue oxygenation allowing the quantitation of tissue hypoxia with positron emission tomography (PET).
