16.6.5 Setting the IBP Waveform
To set the IBP waveform, follow this procedure:
1. Select the IBP numeric area or waveform area to enter the corresponding pressure menu.
2. Select the Setup tab.
3. Set the following properties of the IBP waveform:
â—† Speed
◆ Scale: if Auto is selected, the size of the pressure’s waveform will be adjusted automatically.
16.6.6 Setting the Display Format of Artery Pressure
To set the display format of the artery pressure, follow this procedure:
1. Select the numeric area or waveform area of any arterial pressure to enter the corresponding menu.
2. Select the Setup tab.
3. Set Display Format.
16.6.7 Showing/Hiding the Alarm Limits of Artery Pressure
To set whether to display the alarm limits of the arterial pressure, follow this procedure:
1. Select the numeric area or waveform area of any arterial pressure to enter the corresponding menu.
2. Select the Setup tab.
3. Switch on or off Display Alarm Limits.
16.6.8 Setting the Use PA-D as PAWP Switch
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 23.4Hemodynamic Calculations.
16.6.9 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.
• 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.
• The PPV measurement has been validated only for adult patients.
• PPV calculation may lead to inaccurate values in the following situations:
