Results are expressed as STPD (Standard Temperature and Pressure, Dry) (101.3kPa at an operating temperature of 20°C, dry). When flow
parameters are converted to BTPS (Body Temperature and Pressure, Saturated), water vapour may contribute to an additional volume of up
to 13%.
2
Accuracy may be reduced by the presence of leaks, supplemental oxygen, tidal volumes <100 mL or minute ventilation <3 L/min.
3
Measurement accuracy verified as per EN ISO 10651-6:2009 for Home Care Ventilatory Support Devices (Figure 101 and Table 101) using
nominal ResMed mask vent flows.
Measurement system uncertainties
In accordance with ISO 80601-2-70:2015 the measurement uncertainty of the manufacturer's test equipment is:
For measures of flow
For measures of volume (< 100 mL)
For measures of volume (≥ 100 mL)
For measures of static pressure
For measures of dynamic pressure
For measures of time
Note: ISO 80601-2-70:2015 stated accuracies and test results provided in this manual for these items already include the
relevant measurement uncertainty from the table above.
