Outcome Measures

Primary Outcomes (1)

  • Mask acceptance

    Mask acceptance during inhalational mask induction as measured by the mask acceptance scale (MAS). The MAS is scored on a scale from 1-4 by evaluating if the child is calm and accepting of the mask (4), slightly scared but easily calmed (3), has moderate fear of the mask and is not easily calmed (2), or cries, screams, or is terrified (1) during induction when using the inhalation mask. A higher score is better.
