Brief summary
The direct objective of this study is to determine whether an experienced provider can more adequately and/or easily ventilate an anesthetized patient with the NuMask device as compared to traditional bag-valve-mask ventilation. These are approved masks, being used in the patients routine care. The researchers believe that mean tidal volumes obtained by experienced providers when manually ventilating anesthetized patients with the NuMask device will be larger than when using the traditional bag-valve-mask.
Interventions
The NuMask is a relatively new mask ventilation device that has been registered with the FDA and used in the United States since 2006.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Tidal Volume comparison | 2 minutes (one minute for NuMask, one minute for traditional mask) | Tidal volumes delivered between the two devices will be compared |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Ease of use | 2 minutes | Provider will rate each device for ease of use on a 1-5 scale with 1 being easy and 5 being difficult. |
