4.4.2.1 Settings of invasive pressure measurement
Please ensure the correct setting of the limiting alarm values. They are displayed behind the
measured value, provided this function has been activated. Please make sure that you have not
switched off the acoustic alarm permanently ( = acoustic alarm permanently off).
The right-hand column of the display holds the navigation field, in which you can use the soft keys to carry
out further adjustments or to call off information or help.
Additional settings are accessed by pressing the ICP1 key. For the selection of another measuring location,
this key has a different designation, such as ART. If you have connected additional pressure sensors, other
soft key designations will be displayed with the defined measuring locations.
In this window, the arrow keys can be used to choose whether the pressure signal is to be switched to one
of the two analogue outputs; whether you want to change the settings of the limiting alarm values; and
whether the limiting value monitor of the selected parameters is to be active or not. In addition, select the
measured value to be monitored.
In the measurement of the ICP, other derived values are available apart from the ICP:
• ICP Intra-Cranial Pressure
• ICPA Pulse amplitude of the Intra-Cranial Pressure
• CPP Cerebral Perfusion Pressure (CPP = ART – ICP)
If two intra-cranial pressures (ICP1 and ICP2) are available, the CPP is calculated from ART and ICP1. If
ICP1 fails (because the sensor has been removed or the sensor is defective or another hardware defect
has occurred, for example) and ICP2 only is available, the CPP is calculated from ART and ICP1
automatically. In this case, a sensor alarm is activated for ICP1, but not for CPP because the limiting values
for CPP calculated from ART and ICP2 are observed.
If only one intra-cranial pressure (ICP1 or ICP2) is available, the CPP is calculated from ART and ICP1 or
ICP2, depending on which measuring location has been allocated.
