Hypoxia is a condition in which cells of the body are deprived of oxygen. The reasons for this condition can vary within the body. However, the result is that tissues cannot survive for long without oxygen. Continued oxygen deprivation can eventually...

An inadequate supply of OXYGEN to the brain. Brain structures are particularly vulnerable to interruptions in oxygen supply. Areas most affected include the HIPPOCAMPUS, GLOBUS PALLIDUS and the WATERSHED AREAS OF CORTEX such as the occipito-parietal...

Hypoxia is a decrease in the level of OXYGEN in the BLOOD or tissues below that which is normal. Anaemic HYPOXIA is caused by a loss of haemoglobin (the oxygen-transporting MOLECULE) form the blood; DIFFUSION hypoxia is caused by a transient decrease...

Condition in which tissues are starved of oxygen. The extreme is anoxia (absence of oxygen). There are four types: hypoxemic, from low blood oxygen content (e.g., in altitude sickness); anemic, from low blood oxygen-carrying capacity (e.g., in carbon...

Deficiency in or lack or oxygen. It may occur in newborns during the transition from the maternal supply or oxygenated cord blood to independent breathing. Brain cells are particularly vulnerable to continued...

The medical term used to describe a low blood concentration of oxygen. It may be caused by disease of the heart or lungs, or by abnormal...

Condition in which below-normal levels of oxygen are present in the air, blood, or body tissues, short of...

The condition where oxygen does not reach body tissues or is not utilized by the...
