e. Seat Mask.
(1) Place the mask over the patient's nose and mouth to so that it fits over
the bridge of the nose, extends below the lower lips (figure 2-12), and forms a tight seal.
As the stretched mask is positioned on the patient's face, it will return to its original
shape and the patient's skin will be pulled slightly inward.
Figure 2-12. Positioning the mask.
(2) Place your thumb and index finger of one hand on the mask. Position
the thumb above and the finger below the valve connection. Use the other fingers (on
the same hand) to grip the lower jaw in order to maintain the tight seal of the mask
(figure 2-13).
