Adjust the strap tension
1. Adjust the tension of the side straps. If the bellows on
the prongs or mask are collapsed, the straps are too tight.
The gray side straps should lie low and horizontally across
the infant’s cheeks. Ensure the straps are not resting
against the eyes. Tuck the end of the straps under the
bonnet fold, and tie the ends of the bonnet on top of
the infant’s head.
Inspect the bonnet
After applying the bonnet, inspect it for proper fit and
strap tension.
1. Center the support cradle midline to the forehead and
align to the nasal profile.
2. Place the bottom edge of the bonnet at the brow line,
without covering the eyes. This ensures the proper
placement of the support cradle and correct position of
the generator assembly. If the bottom of the bonnet is
placed too high on the forehead, it affects the alignment
of the interface. This may cause the interface to push up
against the nasal septum or make it difficult to maintain
a seal with the nasal mask or prongs.
3. Cover both ears evenly with the bonnet. This helps
protect the ears and muffle the sound created by the
variable flow generator.
4. Ensure the ears are flat against the forehead, not folded.
Conduct routine checks behind the ear for skin irritation
or moisture buildup.
5. Check that the bonnet is snug enough to maintain
a proper fit and prevent slippage. If it is too tight,
loosen the threading until the interface bellows and the
septum shows.
6. Avoid using a bonnet that is too large. Otherwise, the
bonnet material buckles and does not conform to the
shape of the infant’s head.
7. Confirm the straps lie flat on the infant’s cheek
and are not twisted.
8. Routinely check the measurement of the head
circumference, and adjust the headgear as indicated
to accommodate the infant’s changing head size.
Correct bonnet placement
1. The bottom of the bonnet sits at the brow line.
2. The side straps lie flat and low on the infant’s cheeks.
3. The generator assembly is properly centered.
4. The bonnet covers the ears. The ears lie flat, not folded.
5. The strap is threaded correctly. The bonnet conforms to
the shape of the head.
6. The top of the bonnet is tied off.
7. The support cradle is centered and midline with the
nasal area.
