Notes:
•
The manufacturer reserves the right to change these specifications without notice.
•
The electrical connector end of the heated air tubing is only compatible with the air outlet at the device end and should
not be fitted to the nasal cannula.
•
Do not use electrically conductive or antistatic air tubing.
•
The temperature and relative humidity settings displayed are not measured values.

Measurement system uncertainties
In accordance with ISO 80601-2-74:2017 the measurement uncertainty of the manufacturer's test equipment for measures
of flow is ± 1.5 L/min or ± 2.7% of reading (whichever is greater)
Guidance and manufacturer’s declaration electromagnetic emissions and
immunity
Medical electrical equipment needs special precautions regarding EMC and needs to be installed
and put into service according to EMC information provided in this document.
The Lumis HFT device has been designed to meet EMC standards. However, should you suspect
that the device performance (eg, pressure or flow) is affected by other equipment, move the device
away from the possible cause of interference.
