To set the averaging time, in the parameter setup menu, select [
Sensitivity ] and toggle between [ High ], [ Med ] and
[ Low ]. The corresponding averaging time is about 1 s, 8 s and 12 s respectively.
14.6.5 Setting Up the IBP Wave
In the setup menu for the pressure, you can:

Select [ Sweep ] and then select the appropriate setting. The faster the wave sweeps, the wider the wave is.

Select [ Scale ] and then select the appropriate setting. If [ Auto ] is selected, the size of the pressure’s waveform will
be adjusted automatically.
 Select [

14.6.6 Enabling PPV Measurement and Setting PPV Source
PPV indicates pulse pressure variation. To enable PPV measurement, set [
PPV Measurement
] to [
On
].
You can select the PPV source when PPV measurement is enabled.
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 (“cor pulmonale”).
