  Hypoxia (medical) . Enpsychlopedia
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 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 the air breathed in.
Severe hypoxia induces a blue discolouration of the skin, called cyanosis (haemoglobin is blue when it is not bound to oxygen (deoxyhaemoglobin), as opposed to the rich red colour that it has when bound to oxygen (oxyhaemoglobin)).

 Hypoxia (disambiguation) - Wikipedia, the free encyclopedia
Ischemia is a medical term for hypoxia where there is a restriction in blood supply, generally due to factors in the blood vessels.
Environmental hypoxia in sea water or oxygen depletion, a reduced concentration of dissolved oxygen in a water body leading to stress and death in aquatic organisms.
Oxygen saturation is a relative measure of the amount of oxygen that is dissolved or carried in a given medium and is therefore a measure of hypoxia or hypoxic conditions.

 Brain Anoxia or Hypoxia
Hypoxia is a condition in which there is a decrease of oxygen to the tissue in spite of adequate blood flow to the tissue.
Anoxia and hypoxia, however, are often used interchangeably -- without regard to their specific meanings -- to describe a condition that occurs in an organ when there is a diminished supply of oxygen to the organ's tissues.
Anoxia and hypoxia may be caused by a number of events, such as smoke or carbon monoxide inhalation, high altitude exposure, strangulation, anesthetic accidents, or poisoning.

 HSP in Hypoxia
OBJECTIVE: To characterize the role of the heat shock proteins (hsp) in the cellular response to hypoxic cell damage in the gut; to determine the function of the hsp in the cellular adaptation to hypoxic conditions and development of tolerance to subsequent hypoxic assaults.
Hypoxia: Mice were subjected to hypoxia in a special chamber which provided a controlled atmosphere containing 6% oxygen and the balance made up of nitrogen for 2, 8, and 16 hours.
The results indicate that hsps are expressed in different cellular populations and in different patterns after hypoxia and heat shock.

The threat of fetal hypoxia carries dangers not only for the child but also for the woman giving birth as doctors often proceed quickly to a caesarean section if they feel there is a significant threat of fetal hypoxia.
Warwick Medical School researchers have examined the probes and say that the use of Professor Dale's probes to test for hypoxanthine would give doctors in delivery rooms almost instant data on whether the unborn child faced fetal hypoxia.

Medical officers should remember, however, that the signs and symptoms of many preexisting conditions of sleep-disordered breathing, including Cheyne-Stokes respiration in chronic heart failure and obstructive sleep apnea syndrome, are similar to those seen in altitude periodic breathing.
Because physical standards and medical screening prevent individuals with significant medical problems from entering or remaining in active-duty military service, the types of medical problems that could be present in a military unit at deployment do not represent the full spectrum seen in the civilian sector.
Medical personnel in support of units that are deploying to mountain terrain need to be prepared to prevent and to treat problems related to inadequate hydration.

 Hypoxia
Decreased blood flow is one of the earliest physiological changes observed after the onset of either clinical or experimental diabetes.
The reduction in blood flow is believed to lead to nerve hypoxia, which in conjunction with other metabolic alterations and degenerative processes in different nerve compartments, results in the dysfunction known as diabetic neuropathy.
These results suggest that the transient activation of neurotrophic and angiogenic genes, as opposed to a more sustained effect in response to the chronic injury, may be responsible for the alterations in nerve function and regeneration that characterize the diabetic neuropathy.

Hypoxia occurs as a result of reduced barometric pressure in the aircraft cabin, which approximates the pressure at 5,000 to 8,000 feet above sea level – such as on a mountaintop, for example.
Hypoxia is on the rise among airline passengers, aviation experts believe.
In consultation with medical personnel, the crew may then use an in-flight emergency kit, lower altitude to decrease cabin pressure, or divert the flight to rapidly obtain medical assistance.

When hypoxia lasts for longer periods of time, it can cause coma, seizures, and even brain death.
Treatment depends on the underlying cause of the hypoxia, but basic life-support systems have to be put in place: mechanical ventilation to secure the airway; fluids, blood products, or medications to support blood pressure and heart rate; and medications to suppress seizures.
Advice on the treatment or care of an individual patient should be obtained through consultation with a physician who has examined that patient or is familiar with that patient's medical history.

If seizures occur, some medications are used to suppress them with variable degree of success, including phenytoin, phenobarbital, valproic acid, and general anesthetics.
Sometimes cooling with blankets (hypothermia) is used because much of the brain damage in hypoxia is caused by heat, and those who suffer the condition (if it is caused by drowning in cold water, for example) in cold temperatures have survived longer than those who were affected in higher temperatures.
Complications of cerebral hypoxia include brain death or a "prolonged vegetative state" where basic life functions, such as breathing, blood pressure, sleep/wake cycle, and eye opening may be preserved, but there is no consciousness or response to the environment.
