Setting Ambient Pressure
Ambient pressure depends on your facility’s altitude above the sea level. If your healthcare facility is
located in a tall building, then you may consider the floor altitude influence on the ambient pressure.
The ambient pressure variations due to the weather and air temperature changes usually are not
significant enough and may be ignored.
Verify and, if necessary, adjust the Ambient Pressure setting after your DFM100 gets moved to a different
location, especially to a different altitude.
WARNING: Wrong Ambient Pressure settings can lead to incorrect EtCO
2
readings which may alter the clinical
picture.
Set the Ambient Pressure to the prevalent normal atmospheric pressure for your location. If this value is
not known, use the approximate values from Ta ble 3 on page 27.
