Ventilator Settings Range, Resolution, and Accuracy
Specifications
Pressure support
Range: OFF or 5 mbar to 55 mbar in valve configuration
(P Support)
Range: 6 mbar to 30 mbar in leak in valve configuration
Resolution: 1 mbar
Accuracy: ± (1 mbar + 10%) of P Support + PEEP setting
Default value: 15 mbar
Depends on PEEP when Relative Pressure is set to YES
I:E Ratio (I:E) Range: from 1:1 to 1:4
Resolution: 1/0.1 s
Accuracy: ± 50 ms or 10%, whichever is greater
Default value: 1/2
I/T Ratio (I/T) Range: 20% to 50%
Resolution: 1%
Accuracy: ± 50 ms or 10%, whichever is greater
Default value: 33%
Inspiratory time (Insp Time) Range: 0.3 s to 2.4 s
Resolution: 0.1 s
Accuracy: ± 50 ms or 10%, whichever is greater
Default value: 1.5 s
Depends on: R-Rate, Vt in V SIMV mode
Depends on: R-Rate in P SIMV mode
Respiratory rate (R-Rate) Range: 5 bpm to 60 bpm in V A/C and P A/C modes
1 bpm to 40 bpm in P SIMV and V SIMV modes
Resolution: 1 bpm
Accuracy: ± 1 bpm
Default value: 13
Depends on: Insp Time and Vt in V SIMV mode
Depends on: Insp Time in P SIMV modes
Depends on: Vt in V A/C mode
Inspiratory sensitivity (I Sens) Range: 1P-5
Resolution: 1
Accuracy: NA
Default value: 2
in CPAP, I Sens is set to 2 and is not adjustable
Exhalation sensitivity (E Sens) Range: 5% to 95% of peak flow
Resolution: 5%
Accuracy: ± (4 lpm +10%) of target exhalation flow based
on E Sens within 50ms
Default value: 25%
In CPAP, E Sens is fixed at 25% and is not adjustable.
Ramp (Flow Pattern) Range: Square (SQ), descending ramp (D), sinusoidal (S)
Resolution: N/A
Default value: Descending ramp (D)
In V SIMV, flow pattern is set to square and is not adjustable
