  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.

  3. Acute exacerbation of chronic obstructive pulmonary disease

    en.wikipedia.org/wiki/Acute_exacerbation_of...

    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 ...

    The American Lung Association has stated "there is no evidence that oxygen at the low flow levels used in bars can be dangerous to a normal person's health", but the U.S. Center for Drug Evaluation and Research cautions that people with heart or lung disease need their supplementary oxygen carefully regulated and should not use oxygen bars. [140]

    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 ...

    Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...

  7. Hypercapnia - Wikipedia

    en.wikipedia.org/wiki/Hypercapnia

    The risk of dangerous irregularities of the heart beat is increased. [ 6 ] [ 7 ] Hypercapnia also occurs when the breathing gas is contaminated with carbon dioxide, or respiratory gas exchange cannot keep up with the metabolic production of carbon dioxide, which can occur when gas density limits ventilation at high ambient pressures.
