[Laryngeal mask]. / Mascarilla laríngea.

A laryngeal mask is a very useful instrument to use both in easy as well as difficult handling situations related to the air tract. This mask is placed in the pharynx and it permits a patient to breathe in different modes, either spontaneously or mechanically. Different models are available; some even facilitate the tracheal intubation through the mask. The authors highlight that this type of mask does not protect nor isolate the air tract. As advantages, the authors point out its easy installation; thus, it is an alternative when an air tract presents difficulties; therefore, it is necessary that all personnel who have to deal with the air tract be aware of this mask and know how to handle it.
