Summary

Brief summary (as posted)

Two-handed mask ventilation has been shown to provide higher tidal volume than one-handed mask ventilation. The effects of the two techniques on respiratory mechanics during induction of general anesthesia, however, still need to be determined.

One-handed mask ventilation
description
For the one-handed mask ventilation, only one hand can be used to achieve the face mask seal. The left thumb and index finger form a ''C,'' providing anterior pressure over the mask, while the third, fourth, and fifth fingers form an ''E'' to lift the jaw.

label
Two-handed mask ventilation
description
For the two-handed mask ventilation, the provider's thumb and thenar eminence of each hand are held parallel, adjacent to the mask connector, and depress each side of the mask. The second through fifth digits wrap around and elevate the mandible to draw it anteriorly into the mask establishing both a jaw-thrust and chin-lift maneuver when appropriate.
