Q

True or False

Face masks provide positive airway pressure and gas movement through a patients protected airway

A

False. Fase masks provide positive aiway pressure and gas movement through an unprotected the airway.

Still possible to vomit and aspirate. There is nothing in the vocal cords to prevent aspiration. Patients LIE, could have eaten or full belly

E. No excessive gas leak
F. All the Above

A

F. All the Above

You should not have an excessive gas leak, having a good seal of the mask on the nose and mouth. The pneumatic cuff is there to keep that good seal
