7.3.1.3 Up / Down Arrows
The arrows appear when a function or parameter which can be modified is
selected.
The up arrow increases the chosen value and the down arrow decreases the
value. The arrow selected changes colour when touched.
The arrow can be touched repeatedly to increment the parameter in individual
increments or held down to rapidly change the value. Holding down to rapidly
change the value is limited to steps of 10 increments.
User will have to release and repress the arrow to continue the next rapid
increase of 10 increments. This feature is to prevent any parameter being set to
maximum in one action.
7.3.1.4 Ti (Inspiratory Time) Parameter control
The Ti parameter control functions as described above but increments by 0.01
seconds.
7.3.1.5 Tidal Volume (TTV) Parameter Control
The tidal volume parameter control functions as described but has 3 resolutions.
From 2ml to 6ml the parameter increments in 0.2ml steps (Fine resolution).
From 6ml to 100ml the parameter increments in 1ml steps (Standard resolution).
From 100ml to 200ml the parameter increments in 5ml steps (Coarse resolution).
7.3.1.6 FiO
2
Parameter Control
The FiO
2
parameter control is the only parameter that does not function as
described above. The FiO
2
parameter control allows for rapid setting to 100% O
2
.
The user can increase the percentage of O
2
from the set percentage to 100% by
activating the FiO
2
parameter and holding down the up arrow. (The control is not
limited to steps of 10 increments).
To decrease the percentage of O
2
the parameter is limited to steps of 10
increments.
Note: If the up arrow is held down for a total of 8 seconds, the ventilator will
reset the percentage of O
2
to the original setting. This is a safety feature in
case the touch screen develops a fault.
