Single Portable Pulse-dose-conserving Device vs. Combined Use of Stationary and Portable.

Introduction: Portable oxygen devices simplify and facilitate patient therapy. This study was designed to compare oxygen saturation and patient satisfaction with a portable oxygen concentrator or with a combined system consisting of a fixed device with continuous flow oxygen dispensation and a portable device with pulse dispensation for ambulation.

Methods: This cross-over trial assessed 25 patients with COPD (92% men; mean age 72.2 ± 7.4 years; mean FEV 34.14 ± 12.51%) at four hospitals in Madrid. All patients had previously used the combined system, consisting of a fixed oxygenation system and a portable system for ambulation, with 16 (64%) using stationary and portable concentrators and 9 (36%) using a stationary reservoir and portable liquid oxygen bag. Oxygenation settings at rest and while walking were determined at baseline. Patients were maintained on the previous combined system for one week and then switched to the portable oxygen concentrator for one week. Mean SpO2 over 24 hours was calculated by the software in the oximeter, and compliance was monitored

Treatment and study plan

Inogen

Device

single pulse dose concentrator (Inogen One G2 portable. Inogen) device for 24 hours

Combination system of a portable and a stationary device.

Device

Combination system of a portable and a stationary device (reservoir of liquid oxygen "Liberator 30, Caire" and a liquid Stroller oxygen pack "Caire" for patients using previously liquid oxygen, or a VisionAire5 "Airsep" stationary concentrator and an Inogen One G2 portable "Inogen" concentrator for patients using previously concentrators)

Primary outcomes

  1. Percentage of time desaturated below 90% when using a combined oxygenation system

    Time frame: at day 7

    oxygenation of patient during use of a combined system consisting of a fixed device with continuous flow oxygen dispensation and a portable device with pulse dispensation for ambulation.

  2. Percentage of time desaturated below 90% using single oxygenation system

    Time frame: day 14

    Oxygenation of patient during use of a portable oxygen pulse dose concentrator.
