Thread the gray straps to the bonnet
As one alternative method, to apply the bonnet with gray
straps pre-threaded:
1. Create a loop on both straps. Take the slanted end of the
gray strap and pull through the slit on the opposite end
to form a loop.
2. Starting from the under side of the bonnet, thread up
through the colored hole, down through the center hole
and back up through the last hole.
3. The excess length of the gray strap should be before the
colored hole. When laid flat, the longer part of the strap
is at the back of the bonnet.
4. Pull the bonnet down over the patient’s head and ensure
the gray straps are brought forward and resting on the
side of the face. Attach the support cradle to the bonnet.
5. Use one hand to align the generator with the interface
perpendicular to the nose, and use the other hand to
position the exhaust tube over the support cradle.
Secure the exhaust tube, drive and pressure lines to
the support cradle.
6. While holding the generator assembly in place, take
the gray strap and place the loop over the quick secure
tab. Pull tight on the loop to adjust the tension of the
gray strap.
7. Repeat the process on the other side, and conduct a
final inspection.
Note: During the bonnet application, ensure the straps
are pulled forward and are not caught underneath the
back of the bonnet. If the loop pulls out, pull it open
before attaching it to the quick secure tab. Another
clinician should assist with the application.
The previous section outlined the most common method
for applying the bonnet. However, some clinicians may find
it more convenient or easier to use one of the methods
described in the following pages.
