Die Langzeit-Sauerstoff-Therapie (LTOT) – Was sollten Arzt, Versorger und Krankenkasse wissen?

Abstract

Long-term oxygen treatment (LTOT) has been demonstrated to improve prognosis in patients with chronic respiratory insufficiency. In terms of pathogenesis, improved oxygenation, reduction of pulmonary artery pressure as well as reduction of respiratory work are important. Since there are considerable differences between the LTOT systems, individually tailored therapy is needed. In particular, the mobility aspects of the patients must be taken into consideration. It is important to distinguish between stationary/mobile devices with a liquid oxygen system and stationary/mobile devices with oxygen concentrator. Oxygen titration should be performed in relation to rest and activity phases (e. g. 6 minute walk test) as well as in relation to the sleep phase. Employing devices with demand-controlled valves should be critically examined. This can be undertaken only under physician orders and requires continuous monitoring.

Benefits of an Oxygen Reservoir Cannula versus a Conventional Nasal Cannula during Exercise in Hypoxemic COPD Patients: A Crossover Trial

“…Long-term oxygen (O 2 ) therapy (LTOT) is clearly indicated and recommended as a part of routine clinical practice in patients with hypoxemic chronic obstructive pulmonary disease (COPD) [1,2]. The benefits of LTOT in patients with COPD are well known.…”
