About this study
Official title: Comparing Exercise Capacity in Patients With COPD Using High Flow Nasal Cannula Oxygen vs The Venturi Mask
The aim of this study is to compare exercise capacity in COPD patients through two different systems of supplemental oxygen delivery: High Flow Nasal Cannula Oxygen (HFNCO) and The Venturi Mask (VM).
Read the detailed description
Design: interventional, crossover, randomized.
The main goal of this study is to compare the maximum speed reached in an Incremental Load Treadmill Test (ILTT) and max time tolerated in a Constant Treadmill Load Test (CTLT) while using two different oxygen delivery devices (High Flow Nasal Cannula Oxygen and The Mask Venturi).
Patients will be evaluated through two different kinds of tests: Incremental Load Treadmill Test (ILTT) and Constant Treadmill Load Test (CTLT). Each test will be conducted two times, once using HFNCO and the other time with The VM.
In total, each patient will be evaluated four times on four different visits. The testing order will be randomized through STATA.
The following variables will be measured before, during and after each test:
- Max speed reached in an Incremental load test: Km/h
- Max time tolerate in a Constant Load Test: in seconds
- Oxygen saturation: %
- Dyspnea: Modified Borg scale (0-10)
- Cardiac rate: beats per minute
- Respiratory rate: breaths per minute
- Blood pressure: mmHg
- Lower limbs fatigue: modified Borg scale (0-10)
- Global comfort according to the device used: visual analogue scale (VAS) 0-10
- Conditions
- COPD
- Being tested
- High Flow Nasal Cannula Oxygen, The Venturi Mask

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
High Flow Nasal Cannula OxygenDevice
Also called HFNCO
Exercise capacity testing according to High Flow Nasal Cannula Oxygen in COPD patients involved in a Pulmonary Rehabilitation program.
The Venturi MaskDevice
Exercise capacity testing according to the oxygen Mask Venturi in COPD patients involved in a Pulmonary Rehabilitation program.
| Study group | Role | What they receive |
|---|---|---|
| High Flow Nasal Cannula Oxygen | Experimental | 1. Incremental Load Treadmill Test (ILTT) using HFNCO
2. Constant Treadmill Load Test (CTLT) using HFNCO Receives: Device: High Flow Nasal Cannula Oxygen |
| The Venturi Mask | Active comparator | 1. Incremental Load Treadmill Test (ILTT) using venturi mask
2. Constant Treadmill Load Test (CTLT) using venturi mask Receives: Device: The Venturi Mask |
What is being measured
The primary outcome is the main question the study is designed to answer.
Exercise capacity - Maximum Walking Speed Reached
The exercise capacity test measures the maximum speed (in Km/h) reached during an Incremental Load Treadmill Test (ILTT).
The test begins at a speed of 3 km/h and each minute after, we will increase the speed by 0.5 km/h.
The patient will walk until he exhausts his capacity, once reached, the test will finished.
A second Incremental Load Treadmill Test (ILTT) will be conducted 48 hs afterwards using The Venturi Mask or High Flow Nasal Cannula Oxygen depending on the previous randomization.
Measured: 2 measurements separated by 48 hs
Exercise capacity - Maximum Walking Time Reached
The exercise capacity test measures the maximum time (in minutes) reached during a Constant Load Treadmill Test (CLTT).
The treadmill speed will be constant and set up at 90% of the maximum speed reached in the previous Incremental Load Treadmill Test (ILTT).
The patient will walk at the same velocity until he exhausts his capacity thus ending the test.
A second Constant Load Treadmill Test (CLTT) will be conducted 48 hs following the first Constant Load Treadmill Test (CLTT) using The Venturi Mask or High Flow Nasal Cannula depending on the previous randomization.
Measured: 2 measurements separated by 48 hs

Questions about this trial
What is this clinical trial studying?
A study testing High Flow Nasal Cannula Oxygen and The Venturi Mask in people with COPD, run by Hospital Italiano de Buenos Aires at 1 site in Argentina.
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 2 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 9 May 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Argentina. 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?
Exercise capacity - Maximum Walking Speed Reached (time frame: 2 measurements separated by 48 hs). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02858960, which also lists 22 linked publications.
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 9 May 2017.
