• At a fixed flow rate of supplemental oxygen flow, the inhaled oxygen
concentration will vary, depending on the pressure delivered, the
patient’s breathing pattern, mask selection and leak rate. To monitor
the oxygen concentration the FiO2 sensor is recommended
• Supplemental oxygen flow and pressure must not exceed 15 l/min
and 100 kPa.
• Supplemental oxygen is added before the volume measurement sen-
sor and thereby included in the measurements. However, the oxygen
concentration still has influence on the volume measurement of the
delivered air.
The volume monitoring is based on a normal oxygen concentration
of 21%. If the oxygen concentration is higher, the monitored volume
will deviate from the actual volume as follows:
– 40% oxygen concentration: -2.5% deviation
– 60% oxygen concentration: - 5% deviation
– 80% oxygen concentration: -7.5% deviation
