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. Hypercapnia - Wikipedia

   en.wikipedia.org/wiki/Hypercapnia

   During strenuous exercise the production rate of carbon dioxide can increase more than tenfold over the production rate during rest. Carbon dioxide is dissolved in the blood and elimination is by gas exchange in the lungs during breathing. [10] Hypercapnia is generally caused by hypoventilation, lung disease, or diminished consciousness.

4. Respiratory acidosis - Wikipedia

   en.wikipedia.org/wiki/Respiratory_acidosis

   Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...

5. Oxygen therapy - Wikipedia

   en.wikipedia.org/wiki/Oxygen_therapy

   Careful titration of oxygen therapy should be considered in patients with chronic conditions predisposing them to carbon dioxide retention (e.g., COPD, emphysema). In these instances, oxygen therapy may decrease respiratory drive, leading to accumulation of carbon dioxide (hypercapnia), acidemia , and increased mortality secondary to ...

6. Venturi mask - Wikipedia

   en.wikipedia.org/wiki/Venturi_mask

   A controlled F I O 2 is particularly important for patients whose ventilation is dependent on hypoxic drive, [5] as may be seen in patients with chronic obstructive pulmonary disease. Administration of too much oxygen may lead to a reduction in their respiratory rate and retention of carbon dioxide, and ultimately to reduced consciousness or ...

7. Chronic obstructive pulmonary disease - Wikipedia

   en.wikipedia.org/wiki/Chronic_obstructive...

   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 ...
