14.6.6 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
18.4 Hemodynamic Calculations.
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.
14.6.8 Changing the Pressure Unit
To change the pressure unit, follow this procedure:
1. Select the
Main Menu quick key from the System column select Maintenance input the required
password
select .
2. Select the
Unit tab.
3. Set
Pressure Unit, CVP Unit or ICP Unit.
14.6.9 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.
