An oropharyngeal device for airway management of conscious and semiconscious patients: A randomized clinical trial.

Objective: No oropharyngeal devices exist for use in conscious and semiconscious trauma patients during emergency evacuation, transport, or resuscitation. We aimed to test the hypotheses that the ManMaxAirway (MMA) is better tolerated than the standard Guedel-style device in awake volunteers and that it produces a jaw thrust and improves air flow.

Methods: This was a randomized cross-over study of healthy volunteers with either the MMA or standard device.
