Note: The replacement frequency for the oxygen sensor varies from 6 to 12 months. This
frequency is given as an indication only and varies depending on the duration of ventilation, the
oxygen concentration used and the ambient temperature. When the sensor expires, the
ventilator will tell you that it is time to replace it (see "3 Manual test" on page 48).
