The setting of breathing parameters in
parameters in
Servo-i can be configured in two different
ured in two different
ways, based on:
• I:E ratio (independent of changes of e.g.
pendent of changes of e.g.
the breathing frequency) or,
y) or,
• Inspiration time in seconds (independent
of changes of e.g. the breathing
hanges of e.g. the breathing
frequency), to better meet the
meet the
requirements for infant care.
When the ventilator is configured for setting
gured for setting
of Inspiration time, the unit for Pause time
and Insp. rise time then automatically
cally
switches to seconds. The resulting I:E ratio
:E ratio
for each setting is shown in the upper right
information area of the ventilation mode
mation area of the ventilation mode
window.
As the inspiration time is explicitly set, a
xplicitly set, a
change of for example the Respiratory Rate
Respiratory Rate
will affect the I:E ratio. As a safety precaution,

it will therefore be indicated when the

shown when an SIMV mode is selected,

time when Inspiration time is directly set.
Note: The configuration is done by a service
