  2. Oxygen toxicity - Wikipedia

    en.wikipedia.org/wiki/Oxygen_toxicity

    The biochemical basis for the toxicity of oxygen is the partial reduction of oxygen by one or two electrons to form reactive oxygen species, [56] which are natural by-products of the normal metabolism of oxygen and have important roles in cell signalling. [57] One species produced by the body, the superoxide anion (O −

  3. Effect of oxygen on chronic obstructive pulmonary disease

    en.wikipedia.org/wiki/Effect_of_oxygen_on...

    Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic. [3] [4] With normal lung function, a stimulation to take another breath occurs when a patient has a slight rise in PaCO 2.

  4. Hyperoxia - Wikipedia

    en.wikipedia.org/wiki/Hyperoxia

    Excessive exposure to oxygen can lead to oxygen toxicity, also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning.There are two main ways in which oxygen toxicity can occur: exposure to significantly elevated partial pressures of oxygen for a short period of time (acute oxygen toxicity), or exposure to more modest elevations in oxygen partial pressures but for a ...

    THE AIR WE breathe is about 20 percent oxygen.. When you inhale, oxygen travels from your lungs to your blood and then to your tissues and organs, ensuring that they function properly.

  6. Effects of high altitude on humans - Wikipedia

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

    Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. [48] Symptoms range from shivering and mental confusion, [49] to hallucinations and cardiac arrest. [48] In addition to cold injuries, breathing cold air can cause dehydration, because the air is warmed to body temperature and humidified from body moisture. [15]

    One of those vital signs is blood oxygen level, and in the hospital, it’s measured with a pulse oximeter. Patients with Covid-19 can sometimes have relatively mild symptoms and seem to be ...

  8. Breathing gas - Wikipedia

    en.wikipedia.org/wiki/Breathing_gas

    A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...
