![]() Patients with chronic respiratory failure who need LTOT are at risk of CO 2 retention as a result of the administration of excessive oxygen therefore, it is important to monitor the blood CO 2 level regularly. ![]() An American Thoracic Society/European Respiratory Society position paper reported that an arterial blood gas (ABG) analysis was the preferred method for determining the need for oxygen, as it includes acid-base information ( 5). The number of patients receiving LTOT has increased in Japan ( 4) and is likely to continue to increase because of the aging population.Īccording to the Global Initiative for Chronic Obstructive Lung Disease guideline, LTOT is indicated in patients who have a PaO 2 ≤55 Torr or an SaO 2 ≤88% with or without hypercapnia and in those with a PaO 2 of 55-60 Torr or an SaO 2 of 88% if there is evidence of pulmonary hypertension suggesting congestive heart failure ( 1).Īfter oxygen therapy is started, blood gases should be checked to ensure that oxygenation is satisfactory without retention of CO 2 and/or worsening acidosis. LTOT has also been reported to improve the quality of life in patients with chronic interstitial lung disease (ILD) ( 3). Supplemental long-term oxygen therapy (LTOT) improves the survival, exercise capacity, and quality of life in patients with chronic obstructive pulmonary disease (COPD) and hypoxemia ( 1) as well as in those with sequelae of tuberculosis ( 2).
