The start and stop of volume calculation and determination of the ventilation pa-
rameters are controlled by trigger events. A trigger event can be caused by flow or
pressure in the flow channel (9 Measuring ventilation ratios).
6.14.1 Selection of ventilation mode
By selecting the ventilation mode it is possible to usefully preselect triggers. With
these standard values 90% of measuring tasks can be solved.
You can choose between the following ventilation modes:
• Pediatric ventilation (This measurement takes place using the Flow Low chan-
nel, whereby pressure measurement is conducted at the Pdiff port)
• Adult ventilation
• High-frequency ventilation
6.14.2 Standard triggers
For each ventilation mode the set trigger values are saved. By pressing Reset the
values can be reset to the standard values at any time.
Standard trigger for pediatric ventilation
The measurement of pediatric ventilation takes place using the Flow
Low channel. The required pressure measurement is performed using
a tee on the Pdiff port.
If the Pediatric trigger mode is set, pressure compensation is automatically enabled
for the Low Flow channel.
