Fig. 6: Oxylog 1000 with test set-up for supply pressure warning check
• Set the minute volume adjuster (MV) to left limit stop.
• Set the frequency adjuster (Freq.) to 10 1/min.
• Set the airway pressure adjuster (Paw) to approx. 40 mbar (hPa).
• Set the Air Mix/ No Air Mix selector to the "No Air Mix" position.
• Slowly close the pressure regulator of the test pressure reducer.
• Watch the pressure gauge of the test pressure reducer.
As soon as the downstream pressure reaches 2.2 bar to 1.8 bar, the "Pv"
indicator turns red. The supply pressure is insufficient.
• Slowly open the pressure regulator of the test pressure reducer.
As soon as the downstream pressure reaches 2.3 bar to 2.7 bar, the "Pv"
