General information
Units of measurement for pressure 1 hPa = 1 mbar = 1 cmH2O
100 kPa = 0.1 MPa = 1 bar = 1 kPa x 100
User's operating location At the front at a distance of 1 m (39 in) and a
height of 1.5 m (59 in)
All specified tolerances apply for 20 °C (68 °F),
60 % relative humidity, and 1013 hPa
(760 mmHg).
The accuracies indicated below change accord-
ing to ambient pressure, temperature, and rela-
tive humidity. If one of the ambient conditions is
changed up to the permissible limit, the accu-
racy of the corresponding value can change by
up to 50 %. If more than one of the ambient con-
ditions are changed, the accuracy may change
by up to 100 %.
Example: Accuracy of a measured pressure
value: ±4 % under standard conditions. At
10 °C, the accuracy changes to ±6 %; at 10 °C
and 20 % relative humidity, to ±8 %.
All patient-related volumes and flow values are
standardized to the conditions in the lung.
