3.5.1
Zero adjustment of arterial pressure (AP) and central venous pressure (CVP)
Procedure:
x
Open 3-way-stopcock between pressure transducer and pressure line to ambient pressure.
x
Confirm with the
button as soon as a stable value is displayed.
x
Perform the zero adjustment at the bedside monitor.
x
Set the 3-way-stopcock so that the invasive pressure is transferred to the pressure transducer by the
pressure line.
x
Adjust curve scaling with the respective buttons.
x
If necessary repeat this procedure for the central venous pressure.
x
In cases where continuous central venous pressure is not measured, manually update the value for
the central venous pressure regularly.
CAUTION:
If the option of the continuous CVP measurement is not used, CVP should be updated
as soon as a new value is obtained to accurately calculate SVR and PCCO.
If the zero adjustment is not performed, the blood pressure values may be wrong. Zero adjustment
of the pressure transducer is mandatory.
When the PiCCO
2
is connected to a bedside monitor, perform a zero adjustment of the PiCCO
2
before zeroing the bedside monitor.
