Non-rebreather at Flush Rate Compared to Bag Valve Mask With Assist
A study testing Flush rate oxygen and Flush rate oxygen with assist in people with Acute Respiratory Failure, run by Hennepin Healthcare Research Institute at 1 site in United States.
Trial summary
This crossover investigation enrolls healthy volunteers and compares the exhaled oxygen content (FeO2) between the non-rebreather mask at the flush rate and a bag-valve-mask device at the flush rate, used with active positive pressure assistance. Read more about this study

About this study
This crossover investigation enrolls healthy volunteers and compares the exhaled oxygen content (FeO2) between the non-rebreather mask at the flush rate and a bag-valve-mask device at the flush rate, used with active positive pressure assistance.
- Conditions
- Acute Respiratory Failure
- Being tested
- Flush rate oxygen, Flush rate oxygen with assist
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Flush rate oxygenOther
Using a standard flowmeter (Precision Medical, 8MFA), the flow of oxygen will be fully opened and oxygen will be administered for three minutes.
Flush rate oxygen with assistOther
Using a standard flowmeter (Precision Medical, 8MFA), the flow of oxygen will be fully opened and oxygen will be administered for three minutes. Positive pressure breaths to match the subject's inspiration will be provided during the three minute period.
| Study group | Role | What they receive |
|---|---|---|
| Non-rebreather | Active comparator | This group will have a non-rebreather mask applied to the face and they will receive the flush rate oxygen intervention Receives: Other: Flush rate oxygen |
| Bag-valve-mask | Active comparator | With each inspiration from the subject, the ventilation bag will be gently squeezed to provide positive pressure and augment the amount of oxygen that is received by the subject for each breath. This group will receive the flush rate oxygen with assist intervention. Receives: Other: Flush rate oxygen with assist |
What is being measured
The primary outcome is the main question the study is designed to answer.
Fraction of expired oxygen
The fraction of expired oxygen will be measured after three minutes of preoxygenation
Measured: 3 minutes

Questions about this trial
What is this clinical trial studying?
A study testing Flush rate oxygen and Flush rate oxygen with assist in people with Acute Respiratory Failure, run by Hennepin Healthcare Research Institute at 1 site in United States.
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 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?
The record lists 1 site in United States. 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?

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?
Fraction of expired oxygen (time frame: 3 minutes). 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 NCT02841592, which also lists 1 linked publication.
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 30 Jan 2018; AzTrials last refreshed its copy on 7 Nov 2026.
