what is hypoxia?

Answer 1

Hypoxia is a pathological condition in which the body as a whole (generalised hypoxia) or region of the body (tissue hypoxia) is deprived of adequate oxygen supply. Hypoxia in which there is complete deprivation of oxygen supply is referred to as anoxia.
Hypoxia is distinguished from hypoxemia. Hypoxemia is an abnormally low partial pressure of oxygen (PO2) in arterial blood (West J. "Pulmonary Pathophysiology: The Essentials" 1977 Williams & Wilkins p22). A frequent error is to use the term hypoxemia to mean low oxygen content in arterial blood. It is possible to have a low oxygen content (eg due to anemia) but a high PO2 so incorrect use can lead to confusion.
Generalised hypoxia occurs in healthy people when they ascend to high altitude, where it causes altitude sickness, and the potentially fatal complications of altitude sickness, high altitude pulmonary oedema (HAPE) and high altitude cerebral oedema (HACE). Hypoxia also occurs in healthy individuals when breathing mixtures of gases with a low oxygen content, for example while diving underwater, especially with closed-circuit rebreather systems that control the amount of oxygen in t

Answer 2

Hypoxia is a deprivation of adequate oxygen supply either effecting the whole body or certain tissues. There are many different causes for hypoxia.

Answer 3

Hypoxia literally means "deficient in oxygen." It can refer to:
* Hypoxia (medical), a shortage of oxygen in the body. Hypoxaemia is the reduction of oxygen specifically in the blood; anoxia is when there is no oxygen available at all.

Answer 4

hypoxia means low level of oxygen

Answer 5

Hypoxia is a lack of oxygen in the body. It can lead to cyanosis, a bluish tint color.

Answer 6

hypoxia is oxygen deficit in the blood
