  2. 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.

    en.wikipedia.org/wiki/Oxygen_therapy

    Oxygen therapy, also referred to as supplemental oxygen, is the use of oxygen as medical treatment. [1] Supplemental oxygen can also refer to the use of oxygen enriched air at altitude. Acute indications for therapy include hypoxemia (low blood oxygen levels), carbon monoxide toxicity and cluster headache .

    Oxygen therapy provides supplemental pure oxygen to improve the low blood oxygen level to ease breathing. It is useful for patients experiencing sleep apnea, pneumonia, and asthma. [ 20 ] Corticosteroids , antibiotics , pulmonary rehabilitation therapy , anticoagulants , and surgery can also serve as a medical treatment for ventilation ...

  5. 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 ...

    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. Mechanical ventilation - Wikipedia

    en.wikipedia.org/wiki/Mechanical_ventilation

    Monitoring a patient in mechanical ventilation has many clinical applications: Enhance understanding of pathophysiology, aid with diagnosis, guide patient management, avoid complications, and assess trends. In ventilated patients, pulse oximetry is commonly used when titrating FIO2. A reliable target of Spo2 is greater than 95%. [47]
