Trial summary

Some patients with chronic obstructive pulmonary disease (COPD) need supplementary oxygen during air travel. Guidelines issued by The British Thoracic Society (BTS) for pre-flight evaluation do not discriminate sufficiently between those who need supplementary oxygen during flight, and those who can do without.

About this study

Official title: May Pulseoximetry During Physical Exercise Predict Hypoxemia in COPD Patients During Air Travel?

Some patients with chronic obstructive pulmonary disease (COPD) need supplementary oxygen during air travel. Guidelines issued by The British Thoracic Society (BTS) for pre-flight evaluation do not discriminate sufficiently between those who need supplementary oxygen during flight, and those who can do without. Previous studies have indicated that decreasing hemoglobin oxygen saturation during exercise may predict in-flight hypoxemia. The objective of the present study is to examine if adding exercise oxygen desaturation to the BTS algorithm will better predict requirements for in-flight supplementary oxygen.

Read the detailed description

The British Thoracic Society (BTS) guidelines on pre-flight evaluation for patients with chronic respiratory disease is based on an algorithm where arterial oxygen saturation is the discriminating factor. It has recently been shown that this algorithm does not discriminate sufficiently between patients who need pre-flight evaluation and maybe supplementary oxygen during air travel, and those who can travel by air without supplemental oxygen or further evaluation. Studies have also shown that exercise desaturation may predict in-flight hypoxemia. The objective of the present study is to examine if inclusion of arterial oxygen saturation measured by pulseoximetry during exercise in the BTS algorithm, will increase the sensitivity and specificity of the BTS pre-flight evaluation guidelines.The study also include questionnaires on symptoms during air travel carried out before ande after the pre-flight evaluation.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Obstructive Pulmonary Disease and Hypoxemia, run by LHL Helse at 1 site in Norway.

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 4 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 18 Nov 2010. 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 Norway. 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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00896584, which also lists 4 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 18 Nov 2010.
