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
Range: 1P-5
Resolution: 1
Accuracy: NA
Default value: 2
in CPAP, I Sens is set to 2 and is not adjustable
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.
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
