The following table shows the zeroing steps:
Calibration
Disposable pressure transducers do not have to be
calibrated since they are calibrated by the manu-
facturer to a calibration constant of 100.
For reusable pressure transducers, however, a cal-
ibration constant must be entered again after
lengthy use to obtain reliable measuring results in
future (see page 230).
Individual zeroing of a pressure transducer
from the screen
Simultaneous SmartZero zeroing
1 Make sure the pressure transducer is at the height of the heart. If no Dräger modules are used for
invasive blood pressure measurement (see page 225), Dräger recommends using pressure trans-
ducer holders so that the pressure transducers can be positioned at the correct height.
2 Close the three-way tap in the direction of the patient and open it in the direction of the air.
3 Press the parameter box of the pressure trans-
ducer to be zeroed.
4 Touch the Cal. tab.
5 Touch the required parameter.
3 Touch the SmartZero button on the he-
modynamic module to be zeroed or touch the
Zero all BPs button. Zeus IE detects which
pressure transducers are open and zeroes
them.
6 Touch the Zero button.
Note:
The time of the last successful zeroing procedure is displayed.
If the zeroing could not be performed, the message ART nonstatic, for example, is displayed in the
alarm message field.
z Check waveform display.
If the waveform shows pressure spikes of more than 3 mm during the zeroing, repeat the zeroing pro-
cedure.
If a pressure transducer cannot be zeroed after a second attempt, it should be replaced or DrägerService
should be consulted.
CAUTION
If an IBP parameter which is still to be measured
is physiologically almost static (flat), do not use
the SmartZero function. The channels to be ze-
roed must be zeroed individually with the Zero
button instead. Otherwise the zeroing of the cor-
responding channel will be incorrect.
CAUTION
Perform zeroing before calibration!
The pressure transducer must be zeroed within
five minutes before calibration. Otherwise, this will
lead to incorrect measurements.
