Long-term oxygen therapy (LTOT) has been demonstrated to improve survival in hypoxic chronic obstructive pulmonary disease (COPD) patients when used for >15 h a day.

Criteria for LTOT are a pO2 of <7.3kPa or pO2 7.3–8kPa in patients with evidence of cor pulmonale.

Ambulatory oxygen (AO) can improve desaturation and increase exercise capacity.

Short-burst oxygen therapy (SBOT) may have a place in symptom relief.
