About this study
Official title: Aviation Portable Oxygen Delivery System Based on Pneumatic Pulse Technology
This study aims to investigate dose based oxygen delivery vs. continuous flow of oxygen during simulated altitude conditions as would be experienced after a loss of pressure during commercial aircraft flight. Testing will be performed at rest and during light exercise at a simulated altitude of 15,000 feet in a hypobaric chamber. Performance of the two oxygen delivery systems will be compared using oxygen saturation determined by pulse oximetry.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Integra Pulse Portable- Continuous flowDevice
4 liters per minute oxygen flow
Integra Pulse Portable- Pneumatic pulsed flowDevice
Oxygen flow determined by test device
| Study group | Role | What they receive |
|---|---|---|
| Continuous Flow | Other | Oxygen delivery at 4 liters per minute is the standard method Receives: Device: Integra Pulse Portable- Continuous flow |
| Pneumatic Pulsed Flow | Other | Oxygen delivery using test method Receives: Device: Integra Pulse Portable- Pneumatic pulsed flow |
What is being measured
The primary outcome is the main question the study is designed to answer.
Device performance, as measured by SpO2
The same subject must complete both oxygen delivery system exposures for the data to be used in system performance analysis. Equivalence of the two oxygen delivery systems will be defined as the lack of statistically significant difference (N=20) in SpO2 during the last minute of exercise between the pulse and continuous flow oxygen delivery systems. Average minimum SpO2 over the last minute of the test period will be reported.
Measured: one minute

Questions about this trial
What is this clinical trial studying?
A study testing Integra Pulse Portable- Continuous flow and Integra Pulse Portable- Pneumatic pulsed flow in people with Oxygen Delivery Systems at Altitude, run by Duke University.
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The record says: withdrawn, as of the sponsor's last update on 16 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.
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 was withdrawn before enrolling participants, so there are no results.
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?
Device performance, as measured by SpO2 (time frame: one minute). 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 16 Oct 2018; AzTrials last refreshed its copy on 28 Oct 2026.
