When the ventilator is configured for setting
of Inspiration time, the unit for Pause time and
Insp. rise time then automatically switches to
seconds. The resulting I:E ratio for each setting
is shown in the upper right information area
of the ventilation mode window.
As the inspiration time is explicitly set, a
change of for example the Respiratory Rate
will affect the I:E ratio. As a safety precaution,
it will therefore be indicated when the resulting
I:E ratio passes 1:1 in either direction.
Note:
The touchpad Breath cycle time is not
shown when an SIMV mode is selected,
since there is no need to set Breath cycle
time when Inspiration time is directly set.
The configuration is done by a service
technician with a service card.
5.3.5 End inspiration
SVX-205_XX
End inspiration is the point at which inspiration
changes to expiration in spontaneous and
supported modes of ventilation. A decrease
of the inspiratory flow to a preset level causes
the ventilator to switch to expiration. This
preset level is measured as a percentage of
the maximum flow during inspiration.
For end inspiration, see section Breathing
parameters: default values & allowed settings
(standard configuration) on page 153.
