2. Cerebral hypoxia - Wikipedia

   en.wikipedia.org/wiki/Cerebral_hypoxia

   If oxygen deprivation continues, cognitive disturbances, and decreased motor control will result. [6] The skin may also appear bluish ( cyanosis ) and heart rate increases. Continued oxygen deprivation results in fainting , long-term loss of consciousness, coma , seizures, cessation of brain stem reflexes , and brain death .

3. Hypoxia (medicine) - Wikipedia

   en.wikipedia.org/wiki/Hypoxia_(medicine)

   Hypoxic ischemic encephalopathy (HIE) is a condition that occurs when the entire brain is deprived of an adequate oxygen supply, but the deprivation is not total. While HIE is associated in most cases with oxygen deprivation in the neonate due to birth asphyxia, it can occur in all age groups, and is often a complication of cardiac arrest.

4. Asphyxia - Wikipedia

   en.wikipedia.org/wiki/Asphyxia

   Perinatal asphyxia is the medical condition resulting from deprivation of oxygen to a newborn infant long enough to cause apparent harm. It results most commonly from a drop in maternal blood pressure or interference during delivery with blood flow to the infant's brain .

5. Effects of high altitude on humans - Wikipedia

   en.wikipedia.org/wiki/Effects_of_high_altitude...

   Mitigation may be by supplementary oxygen, pressurisation of the habitat or environmental protection suit, or a combination of both. In all cases the critical effect is the raising of oxygen partial pressure in the breathing gas. [1] Room air at altitude can be enriched with oxygen without introducing an unacceptable fire hazard.

6. Generalized hypoxia - Wikipedia

   en.wikipedia.org/wiki/Generalized_hypoxia

   Generalized hypoxia is a medical condition in which the tissues of the body are deprived of the necessary levels of oxygen due to an insufficient supply of oxygen, which may be due to the composition or pressure of the breathing gas, decreased lung ventilation, or respiratory disease, any of which may cause a lower than normal oxygen content in the arterial blood, and consequently a reduced ...

7. Brain ischemia - Wikipedia

   en.wikipedia.org/wiki/Brain_ischemia

   The symptoms of brain ischemia reflect the anatomical region undergoing blood and oxygen deprivation. Ischemia within the arteries branching from the internal carotid artery may result in symptoms such as blindness in one eye, weakness in one arm or leg, or weakness in one entire side of the body.

8. Hypoxemia - Wikipedia

   en.wikipedia.org/wiki/Hypoxemia

   Low partial pressure of oxygen in the lungs when switching from inhaled anesthesia to atmospheric air, due to the Fink effect, or diffusion hypoxia. Air depleted of oxygen has also proven fatal. In the past, anesthesia machines have malfunctioned, delivering low-oxygen gas mixtures to patients.

9. Altitude sickness - Wikipedia

   This change in pH stimulates the respiratory center to increase the depth and frequency of respiration, thus speeding the natural acclimatization process. An undesirable side-effect of acetazolamide is a reduction in aerobic endurance performance. Other minor side effects include a tingle-sensation in hands and feet.
