Measurement accuracy verified as per ISO 10651-6:2004 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
± 1.5 L/min or ± 2.7% of reading (whichever is greater)
For measures of volume (< 100 mL)
± 5 mL or 6% of reading (whichever is greater)
For measures of volume (≥ 100 mL)
± 20 mL or 3% of reading (whichever is greater)
For measures of pressure
