Sip And Puff Device And User Switch; Sip And Puff Calibration - Sunrise Medical Quickie R-Net Control System Instructions For Use Manual

13.9 Three axis switch and User Switch (Fig 13.5)
Typical applications are head control systems.
The device comprises of three or four direction switches and
a User Switch connected to the Omni via the 9-way D-type
connector. In addition, a normally closed User Switch should
be connected to the Omni via the 1/8" (3.5mm) jack socket.
This switch, although functionally identical to the switch input
on the 9-way D-type connector, is required to provide a fail-
safe emergency stop system.

13.10 Sip and Puff Device and User Switch

(Fig 13.6)
A sip and puff mouthpiece is connected to the Omni via the
pneumatic input. In addition, a User Switch should be
connected to the Omni via the 3.5mm (1/8") jack socket.
This switch is required to provide a fail-safe emergency stop
system.

13.11 Sip and Puff Calibration (Fig 13.7)
If a new Sip and Puff SID is fitted, or re-calibration is required
then your health care professional or authorized dealer will
perform the following calibration procedure to match the Omni
to your operating capabilities.
A screen like the one shown below should appear (Fig 13.7).
Soft Sip
Soft Sip will be highlighted first. You must now make a series of
soft sips. After each sip, a live readout of the current pressure
will be displayed on the screen in the form of a line within the
0 - 100 scale. Repeated soft sips will produce a 'band' of
values. During this process it may be beneficial for you to look
away from the screen. This prevents 'false' values where you
may be trying to attain earlier levels. Once you are satisfied
that you can produce a soft sip consistently within this band,
your health care professional or authorized dealer will save that
range and move on to highlight Hard Sip.

Hard Sip
You must now make a series of hard sips to produce a new
Hard Sip band. Ideally there should be as much difference as
possible between the Soft Sip and Hard Sip values. To aid
the Omni's differentiation between these pressures, your
health care professional or authorized dealer should move
the Threshold Marker, (shown in Fig 13.8 opposite page) , to
the middle of the gap between the hardest soft command and
the softest hard command. Once a suitable threshold is set,
your health care professional or authorized dealer will save
that range and highlight Soft Puff.
