Oxygen and the airways

Oxygen and the airways.

The use of oxygen for the management of patients with acute breathlessness, irrespective of cause, is well established in medical practice. The perception of benefit, even in the absence of measurement of oxygenation, and concerns over adverse outcomes from severe hypoxaemia have driven the use of high-concentration oxygen therapy over many years with little regard to possible harmful effects. ...

Breathlessness and portable oxygen in chronic obstructive airways disease.

Breathlessness was measured in 20 patients with severe chronic obstructive lung disease by the use of a visual-analogue scale. Severe resting arterial hypoxaemia was not a feature. The severity of breathlessness measured in this way did not correlate well with the results of spirometric tests or with walking ability. The use of portable oxygen was studied during simple walking tests for its eff...

Supplemental oxygen and exercise ability in chronic obstructive airways disease.

The influence of supplemental oxygen on exercise performance was assessed in 17 patients with severe airflow obstruction. Exercise capacity was measured by the six minute walking distance, by an endurance walking test, and by an endurance cycling test and comparison was made with performance when the patient was breathing air. In addition, the relation between the flow rate of supplemental oxyg...
