Key Points ➤ Worldwide, millions are prescribed Long-Term Oxygen Therapy (LTOT), defined as oxygen prescribed for at least 15 h/d. ➤ This clinical guideline incorporates recent evidence and integrates differences in home oxygen needs and experiences across patients with different lung diseases, lifestyles, and oxygen supply requirements. Treatment Chronic Obstructive Pulmonary Disease ➤ In adults with chronic obstructive pulmonary disease (COPD) who have severe chronic resting room air hypoxemia, a the ATS recommends prescribing long-term oxygen therapy (LTOT) for at least 15 h/d (S-M). a Severe hypoxemia is defined as meeting either of the following criteria: 1. Pa O2 ≤55 mm Hg (7.3 kPa) or oxygen saturation as measured by pulse oximetry (Sp O2 ) ≤88% 2. Pa O2 = 56–59 mm Hg (7.5–7.9 kPa) or Sp O2 = 89% plus one of the following : edema, hematocrit ≥55%, or P pulmonale on an ECG. ➤ In adults with COPD who have moderate chronic resting room air hypoxemia, a the ATS suggests not prescribing LTOT (C-L). a Moderate hypoxemia is defined as an Sp O2 of 89–93%. ➤ In adults with COPD who have severe exertional room air hypoxemia, the ATS suggests prescribing ambulatory oxygen (C-L). Interstitial Lung Disease ➤ For adults with interstitial lung disease (ILD) who have severe chronic resting room air hypoxemia, the ATS recommends prescribing LTOT for at least 15 h/d (S-VL). ➤ For adults with ILD who have severe exertional room air hypoxemia, the ATS suggests prescribing ambulatory oxygen (C-L). Liquid Oxygen ➤ In patients with chronic lung disease who are mobile outside of the home and require continuous oxygen flow rates of >3 L/min during exertion, the ATS suggests prescribing portable liquid oxygen (LOX) (C-VL).
