  2. 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.

    High flow oxygen may be harmful in those with an acute exacerbation of COPD. In the prehospital environment those given high flow O 2 rather than titrating their O 2 saturations to 88% to 92% had worse outcomes. [14] In specific circumstances high flow oxygen however can be beneficial. [15] Antibiotics and steroids appear useful in mild to ...

  7. Oxygen toxicity - Wikipedia

    en.wikipedia.org/wiki/Oxygen_toxicity

    Pulmonary oxygen toxicity was first described by J. Lorrain Smith in 1899 when he noted central nervous system toxicity and discovered in experiments in mice and birds that 0.43 bar (43 kPa) had no effect but 0.75 bar (75 kPa) of oxygen was a pulmonary irritant. [33] Pulmonary toxicity may be referred to as the "Lorrain Smith effect". [16]
