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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 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 |
|
| 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. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Flush rate oxygen | Other | Using a standard flowmeter (Precision Medical, 8MFA), the flow of oxygen will be fully opened and oxygen will be administered for three minutes. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Fraction of expired oxygen | The fraction of expired oxygen will be measured after three minutes of preoxygenation | 3 minutes |
