Technical data
16.2 General information
Units of measurement for pressure 1hPa = 1mbar = 1cmH2O
100kPa = 0.1MPa = 1bar = 1kPa 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)
Tolerances All specified tolerances apply for ambient condi-
tions of 20 °C (68 °F), 60 % relative humidity,
and 1013 hPa (760 mmHg).
Accuracies 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 can change by up to 50 %. If more than
one of the ambient conditions is 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 %.
Standardization All patient-related volumes and flows are based
on dry oxygen, converted to the conditions in
the lungs (BTPS).
