  2. Oxygen toxicity - Wikipedia

    en.wikipedia.org/wiki/Oxygen_toxicity

    Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O 2 ) at increased partial pressures . Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs , and eyes.

  3. 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 ...

  4. Effect of oxygen on chronic obstructive pulmonary disease

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

    Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.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.

    Subjects take part in hyperbaric oxygen therapy in Florida. There’s no cure for it, and it’s much more than skin-deep—aging takes a severe toll on our neurological well-being. Although ...

  6. Control of ventilation - Wikipedia

    en.wikipedia.org/wiki/Control_of_ventilation

    The pattern of motor stimuli during breathing can be divided into an inhalation stage and an exhalation stage. Inhalation shows a sudden, ramped increase in motor discharge to the respiratory muscles (and the pharyngeal constrictor muscles). [5] Before the end of inhalation, there is a decline in, and end of motor discharge.

  7. Hypoxemia - Wikipedia

    en.wikipedia.org/wiki/Hypoxemia

    Decreased concentration of oxygen in inspired air caused by reduced replacement of oxygen in the breathing mix. Anaesthetics. 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.

  8. Breathing - Wikipedia

    en.wikipedia.org/wiki/Breathing

    Real-time magnetic resonance imaging of the human thorax during breathing X-ray video of a female American alligator while breathing. Breathing (spiration [1] or ventilation) is the rhythmical process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

  9. Nitrogen dioxide poisoning - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_dioxide_poisoning

    Nitrogen dioxide poisoning is the illness resulting from the toxic effect of nitrogen dioxide (NO 2). It usually occurs after the inhalation of the gas beyond the threshold limit value. [1] Nitrogen dioxide is reddish-brown with a very harsh smell at high concentrations, at lower concentrations it is colorless but may still have a harsh odour.
