NCT02828280

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.

Outcome Measures

Primary Outcomes (1)

  • Tidal Volume comparison

    Tidal volumes delivered between the two devices will be compared

    2 minutes (one minute for NuMask, one minute for traditional mask)

Secondary Outcomes (1)

  • Ease of use

    2 minutes

Study Arms (2)

NuMask

Pt's randomized to Numask first will be ventilated for 10 breaths with the NuMask device first, followed by 10 breaths with the traditional face mask

Device: NuMaskDevice: Traditional mask

Traditional mask

patients randomized to traditional mask first will receive 10 breaths by traditional mask, followed by 10 breaths with NuMask

Device: NuMaskDevice: Traditional mask

Interventions

NuMaskDEVICE

The NuMask is a relatively new mask ventilation device that has been registered with the FDA and used in the United States since 2006.
