摘要：

Introduction. - There is doubt concerning the clinical effectiveness of portable oxygen concentrators with a control valve (PCDV) and their appreciation by patients. Objectives. To compare the effectiveness and appreciation of oxygen therapy by PCDV and liquid oxygen by continuous f low (O(2)Liq). Methods. - Nineteen patients with COPD were randomised to receive PCDV or O(2)Liq at rest and during a 6 minute walk test (6MWT). For each mechanism they assessed, by visual analogue scales, the convenience and portability, the noise, and the discomfort of the nasal oxygen delivery. Results. - The 6MW distance was 315 +/- 120 m with PCDV and 325 +/- 114 m with O(2)Liq (P > 0.05). Dyspnoea and the desaturation induced by the 6MWT were identical with both systems (P > 0.05). The time spent with a SaO(2) < 90 % was 289 +/- 69s with PCDV and 242 +/- 130s with O(2)Liq (P = 0.08). PCDV was noisier than O(2)Liq (P < 0.05); there was no difference in convenience and portability or in nasal discomfort. Conclusion. - The PCDV model that we tested was equally effective to O(2)Liq. However, the prescription of this type of system is a matter of personal choice. (C) 2010 SPLF. Published by Elsevier Masson SAS. All rights reserved.
