The demand oxygen delivery system has been reported to improve oxygen delivery 7:1 vs steady flow during rest and exercise in COPD patients. The present study evaluates the DODS during rest and exercise in eight patients with restrictive lung disease. It was concluded that the DODS provides substantial oxygen savings in RLD patients, particularly during exercise.
据报道，需求式氧气输送系统在慢性阻塞性肺疾病（COPD）患者休息和运动时，与稳定流量相比，能将氧气输送量提高7倍。本研究评估了8例限制性肺疾病患者在休息和运动时的需求式氧气输送系统（DODS）。研究得出结论，需求式氧气输送系统能为限制性肺疾病患者大幅节省氧气，尤其是在运动期间。
