4.3.3 Ventilation parameter dependency
If parameters are mutually regulating, an
arrow will appear on the parameter requiring
modification indicationg the required direction.
In this example, P
insp
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
2
Flush min. 2 Vol.% above O
2
setting, max. 100 Vol.%
• Only Volume limit or Volume guarantee possible
• Pinsp min. 2 mbar above PEEP
• Ppsv min. 2 mbar above PEEP
• Pmax min. 2 mbar above PEEP
• Pmanual min. 2 mbar above CPAP
• Ppsv ≤Pinsp
• Pmanual min. 1 mbar above Pmean
• Pmean rec min. 2 mbar above Pmean
• Rise-Time ≤I-time
4.3.4 Locking ventilator parameters
Some Ventilator parameters are “Locked”
to prevent unusual high values.
When this value is reached, a key symbol
appears and a “Notice Signal” will sound.
The high value must be confirmed by pressing
the rotary push knob again.
