Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of our study is to assess if an automated titration of oxygen flow during exertion can be a useful tool to determinate the level of oxygen required by COPD patients that are using oxygen therapy during exercise.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

All patients referred to our centre of oxygen titration during exertion will be offered to participate in our study.

After baseline assessments, patients will have an oxygen titration using two different methods in random order:

* Usual titration protocol will include an manual oxygen increase during a titration 6 minutes walk test
* Automatic titration protocol that will use the automated oxygen titration device to adjust oxygen flow rate during a titration 6 minutes walk test.

After each titration protocol, the efficacy of the titration will be assessed in 3 validation 6 minutes walk tests during which oxygen flow will be set at:

* The manually determined flow rate
* The 95th percentile flow rate of the automatic titration
* The median flow rate of the automatic titration

During validation 6 minutes walk test, oxygen saturation, dyspnea, walked distance and heart rate will be recorded.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

Patients will undergo titration 6 minutes walk test using the standard and the automatic method in random order.
Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Participants
The same device will be used for both oxygen titration protocol and during 6 minutes walk tests.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Manual then automated oxygen titration

First will be performed the manual oxygen titration and then the automatic oxygen titration.

Group Type ACTIVE_COMPARATOR

Free 02

Intervention Type DEVICE

With the manual oxygen titration, the physiotherapist adjust manually the oxygen flow using the FreeO2 device during a titration 6 minutes walk test.

With the automated adjustment oxygen titration, the flow will be self adjusted by the FreeO2 device during a titration 6 minutes walk test. In that hase, the median flow rate and the 95th flow rate will be evaluated during the validation 6 minutes walk test.
