Hypoxia - common causes, symptoms and treatment What is hypoxia? Hypoxic injuries result when there is a substantial or complete lack of oxygen supplied to the brain, despite an adequate supply of blood flow. In severe cases of hypoxia, the person is often in comatose (in a state of unconsciousness) for periods ranging from hours to days, weeks ...

Hypoxic-Anoxic Brain Injury . The brain requires a constant flow of oxygen to function normally. A hypoxic-anoxic injury, also known as HAI, occurs when that flow is disrupted, essentially starving the brain and preventing it from performing vital biochemical processes. Hypoxic refers to a partial lack of oxygen; anoxic means a total lack.

Brain injury can occur as a consequence of a reduction in either cerebral blood fl ow (CBF) or oxygen supply, or both, which can follow cardiac arrest or other acute events which cause severe cardiopulmonary compromise. Although ischaemia and hypoxia cause patho-logically and clinically distinct patterns of brain injury they usually coexist.

HYPOXIA. Unfortunately, our body doesn’t give us reliable signals at the onset of hypoxia – oxygen starvation – unless . we have received special training to recognize the symptoms. In fact, it’s quite the contrary. The brain is the first part of the body to reflect a diminished oxygen supply, and the evidence of that is usually a loss

However, these signs have not been fully studied for their ability to predict hypoxemia and severity of the asthma attack. The objective of this study was to find which of the clinical signs mentioned above are the best predictors of hypoxemia (defined as SpO2 < 92%) in an acute asthma attack. MATERIALS AND METHODS
Hypoxia: developments in basic science, physiology and clinical studies
There is considerable variation in hypoxia tolerance across vertebrates, but even humans manifest a remark-able adaptation to hypoxia when given enough time. It has been estimated that the arterial PO 2 in climbers at the top of Mt Everest is 28 mmHg [7], clearly a level that would cause significant brain injury or death if imposed acutely.
