Effects of walking with a portable oxygen concentrator on muscle oxygenation while performing normal or pursed-lip breathing in patients with interstitial lung disease: a randomized crossover trial.
Therapeutic advances in respiratory disease（2023）
摘要
Acute exposure to PLB did not improve symptoms, muscle oxygenation, or SpO; however, it decreased the walking distance in the normoxemia group. POC improved leg muscle oxygenation in ILD patients with EID. The use of PLB and POC should be prescribed according to disease characteristics and severity.
