Results are expressed as STPD (Standard Temperature and Pressure, Dry). Use the following table to convert the STPD flow setting to BTPS
(Body Temperature and Pressure, Saturated) flow.

Accuracy may be reduced by the presence of leaks, supplemental oxygen, tidal volumes <100 mL or minute ventilation <3 L/min.

Pressure accuracy - Bi-level modes
Maximum dynamic pressure variation according to ISO 80601-2-70:2015 and ISO 80601-2-70:2020
Device with HumidAir 11 humidifier tub / side cover and air tubing:
Inspiration/Expiration mean error ± standard deviation (cm H2O [hPa]): 1±0.1
Note: Refer to the relevant measurement uncertainty from the Measurement system uncertainties table.
% of Inspiratory Phase for calculation: > 60
% of Expiratory Phase for calculation: > 66
Note: For each inspiratory and expiratory breath phase, the data time slot starts immediately after the initial transient
overshoot/undershoot period and ends at the point when flow diminishes to an absolute value equivalent to its starting point,
towards the end of the breath phase.
