Instructions for use Zeus Infinity Empowered SW 2.n 237
Monitoring
L Catheter size
M Injection volume
N Baseline detection mode: Auto, Man.
O Computation constant: The setting for the
computation constant for the selection of cathe-
ter type Other (P).
C.O. calculations
z Touch the Cardiac calculat. (Q) tab.
The Cardiac calculat. page contains the results of
four C.O. measurements, derived hemodynamic
parameters and the mean values calculated from
them.
Hemodynamic calculations
If C.O. measurements are performed, Zeus IE au-
tomatically calculates different derived hemody-
namic parameters, provides them with a time
marker and stores them in a special database.
The values in the dark fields may be entered and
modified manually.
z Touch the Save button (R).
The table data is ultimately saved in the calculation
trends, see page 184. At least the C.O. or PWP
value must be measured. The time in the calcula-
tion trends is the time when the Save button was
touched.
Hemodynamic parameters
A calculation is based on the values from the follow-
ing hemodynamic parameters:

CAUTION
To obtain reliable calculation results, the following
should be observed:
Ensure that the patient data has been entered
correctly.
A measurement of the pulmonary wedge pres-
sure and a measurement of the cardiac output
must be performed. Otherwise, the result display
is incomplete.
Parameter Designation
HR Current heart rate
ART M Current mean arterial pressure
PA M Current mean pulmonary artery
pressure
PWP Latest value of the pulmonary wedge
pressure
CVP Current central venous pressure
C.O. Latest value of cardiac output
Weight Entered body weight of the patient
WARNING
Make sure that the present weight is not the
patient's weight on admission, but the current
weight. An incorrect weight can lead to incor-
rect calculation results and hence, an incor-
rect clinical assessment and treatment of the
patient.
