Setting the Use PA-D as PAWP Switch (only available for the independent
external display)
You can set whether PA-D value is used to replace PAWP value for hemodynamic calculation. To do so, follow this
procedure:
1.
Select the PA numeric area or waveform area to enter the
PA
menu.
2.
Select the
Setup
tab.
3.
Switch on or off
Use PA-D as PAWP
.
For more information on hemodynamic calculation, see
14.6.7
Enabling PPV Measurement
PPV indicates pulse pressure variation. When measuring the arterial pressure (except PA), the PPV measurement
is available. To enable the PPV measurement, follow this procedure:
1.
Select the IBP numeric area or waveform area to enter the corresponding pressure menu.
2.
Select the
PPV Setup
tab.
3.
Switch on
PPV Measure
.
You can select PPV source after enabling the PPV measurement.
WARNING
•
This monitor can calculate PPV from beat-to-beat values of any arterial pulsatile pressure. The
circumstances under which the calculation of a PPV value is clinically meaningful, appropriate and
reliable must be determined by a physician.
•
The clinical value of the derived PPV information must be determined by a physician. According to
recent scientific literature, the clinical relevance of PPV information is restricted to sedated patients
receiving controlled mechanical ventilation and mainly free from cardiac arrhythmia.
•
PPV calculation may lead to inaccurate values in the following situations:
◆
at respiration rates below 8 rpm
◆
during ventilation with tidal volumes lower than 8 ml/kg
◆
for patients with acute right ventricular dysfunction (“corpulmonale”).
•
The PPV measurement has been validated only for adult patients.

Overlapping IBP Waveforms
The IBP waveforms can be displayed together. To combine IBP waveforms, follow this procedure:
1.
Access
Tile Layout
by either of the following ways:
◆
Select the
Screen Setup
quick key
→
select the
Tile Layout
tab.
◆
Select
Main Menu
quick key
→
from the
Display
column select
Tile Layout
.
2.
Select the waveform area where you want to display the overlapped IBP waveforms, and then select the IBP
waves to be overlapped on the left side of the same line.
3.
Repeat step 2 in another waveform area if needed.
4.
Select
to save the setting and exit the window. The main screen will display the overlapped IBP waves.
