April 15, 2020 updated by: Klaus Kenn

Effects of an Oxymizer Pendant Cannula Versus a Conventional Nasal Cannula During Endurance Shuttle Walk Test (ESWT) in Hypoxemic Patients With Idiopathic Pulmonary Fibrosis

Aim of this study is to investigate the effects of an Oxymizer pendant nasal cannula in hypoxemic patients with idiopathic pulmonary fibrosis during walking.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

Patients will be recruited during an inpatient pulmonary rehabilitation program. They will perform three shuttle walk tests on three consecutive days (see below). While performing those tests, the patient's prescribed oxygen flow rate is applicated either through the conventional nasal cannula (CNC) or the Oxymizer.On the first day, patients perform an incremental shuttle walk test to determine maximum walking speed using a conventional nasal cannula.

On two consecutive days, patients will perform two endurance shuttle walk tests at 85% of the maximum incremental shuttle walk test speed. Supplemental oxygen will be provided via nasal cannula at the prescribed oxygen flow rate. Patients will be randomly assigned to perform one test with the Oxymizer and the other one with a conventional nasal cannula.

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.

What is the study measuring?

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.
Outcome Measure
Measure Description
Time Frame
Endurance shuttle walk test distance
Time Frame: at baseline, at isotime of endurance shuttle walk test and at the end (maximum 20 min) of endurance shuttle walk test
Distance patients walk during an endurance shuttle walk test

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
