Bag Valve Mask vs Non-rebreather at Flush Rate

Not Applicable

Completed

• Conditions: Respiratory Failure
• Interventions: Other: Flush rate oxygen using a standard flowmeter (Precision Medical, 8MFA). See description for details. This is specific.

• Registration Number: NCT02798302
• Lead Sponsor: Hennepin Healthcare Research Institute

Brief Summary

Healthy volunteers will participate in a crossover trial comparing preoxygenation with a non-rebreather mask to a bag-valve mask (with and without a simulated mask leak) at the flush rate of oxygen (fully opening standard oxygen flowmeter).
