14-6 Passport 12/Passport 8 Operator’s Manual
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”).
The PPV measurement has been validated only for adult patients.
