About this study

Official title: Comparison of the Effects of Two Oxygen Delivery Systems on Arterial Blood Gases: Non-rebreather Mask Versus Double-trunk Mask

This study will compare the impact of the Double-Trunk Mask (DTM) with the Non-Rebreather Mask (NRM) on the blood gases of patients with severe hypoxemia.

Read the detailed description

The Double-Trunk Mask (DTM) is a device designed to increase the fraction of inspired oxygen in patients who receive oxygen therapy. The mask is composed of a regular aerosol mask with corrugated tubing (15 cm length) inserted into two lateral holes.

Each included patient will wear the standard Non-Rebreather Mask (NRM) which is the standard delivery oxygen system for patients with acute severe hypoxemia. Then the patients will wear the DTM for 30 minutes. Finally the DTM will be replaced by the NRM for the next 30 minutes. The impact of both oxygen delivery system will be assessed by measuring the change of blood gases with each system.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Double-Trunk MaskDevice

    The DTM (oxygen delivery system) is worn by the patient for 30 minutes.

  • Non-Rebreather maskDevice

    The NRM (standard oxygen delivery system) is worn by the patient for 30 minutes.

What is being measured

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

  1. Changes in PaO2

    Oxygen tension (PaO2) in mmHg will be analyzed from a sample taken from the arterial system

    Measured: At baseline and 30 minutes after wearing DTM

Secondary outcomes (5)
  1. Changes in PaCO2

    Carbon dioxide tension (PaCO2) in mmHg will be analyzed from a sample taken from the arterial system

    Measured: At baseline and 30 minutes after wearing DTM

  2. Changes in pH

    Potential of Hydrogen (pH) will be analyzed from a sample taken from the arterial system.

    Measured: At baseline and 30 minutes after wearing DTM

  3. Changes in respiratory rate

    Respiratory rate is measured during one minute by visual inspection.

    Measured: At baseline and 30 minutes after wearing both systems

  4. Comfort with the oxygen delivery systems

    A Likert scale from -5 to +5 will be used to measure the subjective comfort of the patient while wearing both oxygen delivery systems

    Measured: 30 minutes after wearing both systems

  5. Dyspnea with the oxygen delivery systems

    A Visual Analogic Scale 0 to 10 will be used to measure the dyspnea of the patient while wearing both oxygen delivery systems

    Measured: 30 minutes after wearing both systems

Questions about this trial

What is this clinical trial studying?

A study testing Double-Trunk Mask and Non-Rebreather mask in people with Hypoxemia, run by Cliniques universitaires Saint-Luc- Université Catholique de Louvain at 3 sites in Belgium.

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 3 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 8 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Belgium. 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?

Changes in PaO2 (time frame: At baseline and 30 minutes after wearing DTM). 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 8 Feb 2022.
