Continuous haemodynamic determination
The following parameters are derived by the PULSION PiCCO

, analyzing the arterial pressure curve beat by
beat. The parameters can alternatively be displayed as absolute parameters or indexed to the patient´s body
characteristics.

Moreover, central venous pressure (CVP) in mmHg can be measured continuously.
3.3.1
MAP / CVP / HR
MAP (Mean Arterial Pressure)
Mean arterial pressure is the mean value of the blood pressure in the arterial system.
CVP (Central Venous Pressure)
Central venous pressure is the average blood pressure directly before the right heart.
HR (Heart Rate)
Heart rate is the number of heart beats per minute.
3.3.2
PCCO
Pulse contour cardiac output is the continuously determined cardiac output from the pulse contour analysis.
CAUTION:
As the pulse contour cardiac output of children has not been sufficiently validated thus
far, the CO should be checked by thermodilution before therapeutic interventions.
Recalibration is recommended with significant changes in haemodynamic conditions, such as
volume shifts or changes to medication.
