Abstract:
In mechanically ventilated patients, Pulse Pressure Variation (PPV) has been shown to be a useful parameter to guide fluid management. We evaluated a real-time automated PPV-algorithm by comparing it to manually calculated PPV-values. In 10 critically ill patients, blood pressure was measured invasively (IBP) and non-invasively (CNAP(®) Monitor, CNSystems Medizintechnik, Austria). PPV was determined manually and compared to automated PPV values: PPVmanIBP vs. PPVautoIBP was -0.19 ± 1.65% (mean bias ± standard deviation), PPVmanCNAP vs. PPVautoCNAP was -1.02 ± 2.03% and PPVautoCNAP vs. PPVmanIBP was -2.10 ± 3.14%, suggesting that the automated CNAP(®) PPV-algorithm works well on both blood pressure waveforms but needs further clinical evaluation. © 2013 Elsevier Ltd.
