4Tighten the side lower (Fig. 3) and then the side
upper Velcro straps (Fig. 4) to achieve a secure and
comfortable fit.
5Adjust the top Velcro strap (Fig. 5) with very slight
tension to add stability to the fit of the mask. The
mask should be secure but not overly tight.
6The fitted mask should look like this (Fig. 6):
Note: The top of the mask frame should not touch the
patient’s forehead. In most cases, the top of the mask
frame should be some distance away from the patient’s
forehead.
7Turn the ventilator on. If you detect air leaks
around the cushion, reposition the mask on the
patient’s face to achieve a better seal. You may
also need to readjust the Velcro straps.
Note: When the ventilator system is delivering positive
pressure, the Mirage cushion inflates to float gently on
the patient’s face, forming a secure and comfortable
seal without the need for tight headgear. Pulling the
headgear too tightly may reduce the effectiveness of
the mask.
