Technical data
Pressure rise time (Slope) 0 to 2 seconds;
±20 % of the set value or ±200 ms (the larger
value applies)
Ratio of inspiratory time to expiratory time 1:50 to 50:1
Time at upper pressure level (Thigh) in PC -
APRV mode
0.2 to 10 s
±10 % of the set value or ±100 ms (the larger
value applies)
Time at lower pressure level (Tlow) in PC -
APRV mode
0.2 to 10 s
±10 % of the set value or ±100 ms (the larger
value applies)
Inspiration termination criterion (Insp. term.) 5 to 80 %PIF
±20 % of the set value or ±2.5 L/min (the larger
value applies)
Percentage ratio of plateau time to inspira-
tory time of the mandatory breaths in the VC
- CMV , VC - SIMV, and
VC - SIMV / PS
(%Tplat)
0 to 60 %
±20 % of the set value or ±200 ms (the larger
value applies)
Inflation time (Duration) including rising and
falling slopes in the One-step recruitment
maneuver
3 to 40 s
±10 % of the set value
Number of breaths at each level
(Breaths/Step), with the exception of the
highest level in the Multi-step recruitment
maneuver
1 to 20
Number of breaths at the highest level
(Breaths@Max) in the Multi-step recruitment
maneuver
1 to 20
Reminder for repeated One-step recruitment
or Multi-step recruitment maneuver
Off, 10 to 180 min
±1 min
Volume-based and flow-based settings:
Tidal volume VT 20 to 2000 mL, standardized to BTPS condi-
tions
±10 % of the set value or ±15 mL (the larger
value applies)
The applied VT is corrected by the determined
breathing hose compliance. The applied VT is
also corrected by the sampling flow of the built-
in patient-gas measurement module as soon as
CO
2 respiratory phases are detected.
Trigger sensitivity Trigger 0.3 to 15 L/min
±20 % of the set value or ±1 L/min (the larger
value applies)
Ventilator (continued)
