4.3.3 Ventilation parameter dependency
If parameters are mutually regulating, an arrow will
appear on the parameter requiring modification
indication the required direction.
In this example, Pinsp is being reduced but is NOT
able to be reduced further as it is limited by the
PEEP setting. The limiting value is indicated by the
arrow.

List of dependencies:
• O

Flush :
minimum 2 Vol% above O

setting, max. 100 Vol%
• PDUO :
minimum 2 mbar over PEEP
• Pmanual :
minimum 2 mbar over CPAP
4.3.4 Locking ventilator parameters
Some ventilator parameters are “Locked”
to prevent unusual high values.
When this value is reached a key symbol
will appear and a “notice signal” will sound.
The high value must be confirmed by pressing the
Rotary Pulse knob again.
