What is Hypoxia?
Types of hypoxia. Hypoxia can be classified as local if it is affecting a specific area of the body and generalized if it involves the whole body. When there is a complete deprivation of oxygen supply in the body the term anoxia is used.

Hypoxia 101 US EPA. Lock. Primary navigation.
Ultimately, hypoxia causes a severe decrease in the amount of life in hypoxia zones. Hypoxia also affects the ability of young fish or shellfish to find the food and habitat necessary to become adults. As a result, fish and shellfish stocks may be reduced or become less stable because less young reach adulthood.

Cerebral hypoxia: MedlinePlus Medical Encyclopedia.
Cerebral hypoxia is a medical emergency. Call 911 or the local emergency number immediately if someone is losing consciousness or has other symptoms of cerebral hypoxia. Prevention depends on the specific cause of hypoxia. Unfortunately, hypoxia is usually unexpected. This makes the condition somewhat difficult to prevent.

Neonatal hypoxia: physiology.
The response to hypoxia varies on the age of the neonate. During the first 2 to 3 weeks of life, hypoxia during the neonatal period will cause a transient hyperventilation that is then followed by ventilator depression. The transient hyperventilation will be abolished if the neonate is hypothermic.
Recognition of chronic hypoxia and pre-existing foetal injury on the cardiotocograph CTG: Urgent need to think beyond the guidelines ScienceDirect. ScienceDirect.
Chronic utero-placental insufficiency may result in progressive hypoxia culminating in fetal decompensation and acidosis and this is termed chronic or long-standing hypoxia. It is essential to recognise the features of chronic hypoxia on the CTG trace so as to institute timely and appropriate action.
impact of hypoxia and its modification of the outcome of radiotherapy Journal of Radiation Research Oxford Academic.
However, despite the fact that the potential of hypoxia to modify radiation response was first identified 100 years ago, that we have known for some 60 years as to why hypoxia influences radiation response, and that almost 40 years of clinical trials have clearly shown we can successfully modify hypoxia, hypoxic modification has still not been established as a standard treatment with radiotherapy.
Lactic acidosis not always due to tissue hypoxia: an instructive case report.
Tissue hypoxia is by no means the only cause of lactic acidosis. The term type A lactic acidosis is used to describe lactic acidosis resulting from tissue hypoxia and type B lactic acidosis is used to describe lactic acidosis occurring in the context of adequate perfusion and well-oxygenated tissues.

The depths of onset of hypoxia and anoxia were then interpolated between sampling stations producing two surfaces representing the depth at which hypoxic and anoxic conditions respectively are found. The volume and area of hypoxia and anoxia have been calculated and the results have then been transformed to maps and diagrams to visualize the annual autumn oxygen situation during the analysed period.
What is a dead zone?
The second largest dead zone in the world is located in the U.S, in the northern Gulf of Mexico. National Centers for Coastal Ocean Science. Dealing with Dead Zones: Interview with NOAA Hypoxia Expert audio podcast. Hypoxia and Nutrient Pollution Overview.
Hypoxia PISCO.
However, since 2002 coastal hypoxia has recurred off of Oregon every summer, including many years with severe hypoxia. PISCO scientists are working to understand how upwelling, a normal event that brings rich, life-giving water to the Oregon coast, can turn deadly, causing one of the largest known hypoxic dead" zones" in the world.
