Examples of hypoxia in the following topics:
-
- Hypoxia, or hypoxiation, is inadequate oxygen supply to the body as a whole (generalized hypoxia) or a region of the body (tissue hypoxia).
- Hypoxia, or hypoxiation, is a pathological condition in which the body as a whole (generalized hypoxia) or a region of the body (tissue hypoxia) is deprived of adequate oxygen supply.
- Hypoxemic hypoxia is a generalized hypoxia, with an inadequate supply of oxygen to the body as a whole.
- The term "hypoxemic hypoxia" specifies hypoxia caused by low partial pressure of oxygen in arterial blood.
- In severe hypoxia, or hypoxia of very rapid onset, changes in levels of consciousness, seizures, coma, priapism, and death occur.
-
- They can be desensitized over time from chronic hypoxia (oxygen deficiency) and increased carbon dioxide.
- Chemoreceptor feedback also adjusts for oxygen levels to prevent hypoxia, though only the peripheral chemoreceptors sense oxygen levels.
-
- Anemia is a decrease in number of red blood cells or less than the normal quantity of hemoglobin in the blood resulting in tissue hypoxia.
- Because hemoglobin (found inside RBCs) normally carries oxygen from the lungs to the tissues, anemia leads to hypoxia (lack of oxygen) in organs.
-
- This prevents oxygen binding to hemoglobin, reducing the oxygen-carrying capacity of the blood, leading to hypoxia.
- Carbon monoxide also binds to cytochrome oxidase with less affinity than oxygen, so it is possible that it requires significant intracellular hypoxia before binding.
-
- People with ARDS usually present with shortness of breath, tachypnea leading to hypoxia, and providing less oxygen to the brain occasionally causing confusion.
-
- Pulmonary edema, especially in the acute setting, can lead to respiratory failure, cardiac arrest due to hypoxia, and death.
-
- Cocaine appear to exert a number of its effects through peripheral vasoconstriction leading to fetal hypoxia.
-
- Erythropoiesis can be stimulated by the hormone erythropoietin, which is synthesized by the kidney in response to hypoxia (systemic oxygen deficiency).
-
- Erythropoietin is released in response to hypoxia in the renal circulation.
-
- Some physiologists have suggested the lack of oxygen itself causes capillary beds to vasodilate by the smooth muscle hypoxia of the vessels in the region.
