BACKGROUND: Portable oxygen devices simplify and facilitate patient therapy. This study was designed to compare S(pO2) and patient satisfaction with a portable oxygen concentrator or a combined system consisting of a fixed device with continuous-flow oxygen dispensation and a portable device with pu

BACKGROUND: Most patients on long-term oxygen therapy use stationary oxygen delivery systems. It is not uncommon for guidelines to instruct patients to use tubing lengths no longer than 19.68 ft (6 m) when using an oxygen concentrator and 49.21 ft (15 m) when using cylinders. However, these concepts

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
