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

March 5, 2014 updated by: Aina M Yañez, Hospital Son Espases

Oxygenation Using a Single Portable Pulse-dose-conserving Device Compared to Combined Use of Stationary and Portable Oxygen Delivery Devices.

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

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

36 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
