Molding the Mask

Before you Begin
Steps
NOTE: If the patient's head is too large or has anatomical abnormalities, the posts may be
adjusted to a different level. Usually, the positions of the vertical posts do not need to be changed
(position C and U; see ⑥onFigure 27).
Always mount the vertical posts to the mask ring before mounting the mask to the vertical
posts.
If lesions or open wounds are present on the patient's face, cover them using plastic wrap
or adequate dressings before you mold the mask.
If the temperature of the softened mask is too high, the patient may suffer skin irritations or
burns.
How to Mold the Rear Mask
Steps
60
Have patients remove all items from their heads (toupee, false teeth, hearing aid, ear-
1.
rings, etc.).
2. Heat a water bath to 70° - 80°C (158° - 176°F).
As the material can stick to porous surfaces after activation, covering the patient's hair
3.
with plastic foil is recommended.
4. Line up all necessary clips and spacers.
5. Position the vertical posts at ear height.
Place the head of the patient into the mask ring and onto the headrest, so that the
6.
back of the head rests comfortably on the headrest.
Place the rear mask in the heated water bath until the mask becomes transparent (ap-
1.
proximately 40 to 60 seconds).
2. Remove the mask from the bath and place it on a towel to dry.
