If the measured O2 concentration is below the set value by more than 5 vol.% or concentration is below 18 vol.% which is independent of settings; gas delivered in O2 supply line is not O2; O2 sensor faulty or exhausted; O2 cell uncalibrated; gas module for O2 faulty. Regularly check the cell status in quick menu SYSTEM STATUS/O2 cell. The O2 cell should be exchanged if <10% estimated remaining capacity is indicated.
The oxygen supply is crucial because O2 is added to the air that is used to provide mechanical ventilation. Most patients need a higher concentration of oxygen than is present in normal atmospheric air.
WARNING! The sealed unit of the O2 cell contains a caustic liquid which may cause severe burns to the skin and eyes. In case of contact, immediately wash the affected area continuously with water for at least 15 minutes and seek medical attention, especially if the eyes are affected.
Before you start, unpack the O2 cell at least 15 minutes before replacement. Turn the ventilator system off using the on/off switch on the patient unit. Make sure to disconnect the ventilator system from the power and gas supply.
