About this study

Official title: Effects on an Experimental Dyspnea by Thoraco-abdominal Elastic Strapping of the High Flow Nasal Cannula

To develop an experimental model of dyspnea by external thoraco-abdominal elastic strapping at rest in order to study the mechanisms involved in the relief of dyspnea by the administration of high flow by nasal cannula (HFNC).

Read the detailed description

This study will measure the effect of HFNC on an experimental model of dyspnea induced by thoraco-abdominal elastic strapping on healthy subjects at rest.

The study will also compare the effects on dyspnea of the administration of high flow nasal cannula with and without oxygen added.

Being tested
Optiflow with an inspired fraction of oxygen of 100%, Optiflow with an inspired fraction of oxygen of 21%

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effects of high flow nasal cannula on strapping induced type of dyspnea

    Evaluated by visual annylogic scale

    Measured: One hour

Secondary outcomes (1)
  1. Compare the effect of the high flow by nasal cannula with and without oxygen on an experimental dyspnea, evaluated by the differences of changes in the visual analogic scale

    Evaluated by visual annylogic scale

    Measured: One hour

Questions about this trial

What is this clinical trial studying?

A study testing Optiflow with an inspired fraction of oxygen of 100% and Optiflow with an inspired fraction of oxygen of 21% in people with Dyspnea and Healthy Volunteers, run by Association pour le Développement et l'Organisation de la Recherche en Pneumologie et sur le Sommeil at 2 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effects of high flow nasal cannula on strapping induced type of dyspnea (time frame: One hour). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2019.
