Have you heard about hypoxia? Try to gather information about it, and discuss with your friends.

Hypoxia is a condition characterised by an inadequate or decreased supply of oxygen to the lungs. It is caused by several extrinsic factors such as reduction in pO2, inadequate oxygen, etc. The different types of hypoxia are discussed below.

Hypoxemic hypoxia
In this condition, there is a reduction in the oxygen content of blood as a result of the low partial pressure of oxygen in the arterial blood.
Anaemic hypoxia
In this condition, there is a reduction in the concentration of haemoglobin.
Stagnant or ischemic hypoxia
In this condition, there is a deficiency in the oxygen content of blood because of poor blood circulation. It occurs when a person is exposed to cold temperature for a prolonged period of time.
Histotoxic hypoxia
In this condition, tissues are unable to use oxygen. This occurs during carbon monoxide or cyanide poisoning.

Lack of adequate oxygen supply to whole body or a part is called hypoxia. Hypoxia generally happens because of a mismatch between oxygen demand and supply.

Hypoxia is the condition in which there is a deficiency of oxygen at the tissue level.

Arterial hypoxia: It’s because of low level of oxygen in the blood. It occurs when the atmosphere does not contain enough oxygen and there is obstruction in the respiratory passage.

Anaemic hypoxia: It is due to very low level of haemoglobin in the blood.

Stagnant hypoxia: It is due to the inadequate blood flow to deliver oxygen to the tissue.

Histoxic hypoxia: It is due to the presence of toxic substances in the oxygen inhaled,

e.g.: Cyanide poisoning.
