30.2.3 Pressure
Real Time Pressure: Resolution 1mbar, accuracy
±1mbar
Drift detection: detects drift when there is a
pressure difference of more
than 5mbar between the two
pressure transducers. Only
active when the measured
pressure is below 70mbar.
Sampling Time: 2ms
Peak Pressure: 0 to 175 mbar (resolution
1mbar, accuracy ±0.75% of
full scale range)
PEEP Pressure: 0 to 175 mbar (resolution
1mbar, accuracy ±0.75% of
full scale range)
Mean Pressure: -175 to 175 mbar (resolution
1mbar, accuracy ±0.75% of
full scale range)
Delta P In HFO combined mode
Delta P is measured during
expiration only.
30.3 Exhalation Block Port Jet Sizes
Reverse or negative jet: Ø 1.45/1.55 mm
Forward or positive jet: Ø 1.25/1.35 mm
Mean or 3rd jet: Ø 0.60/0.62 mm
30.4 Alarms

Low Pressure:
Autoset when patient pressure controls are
adjusted, or manually
adjustable.
