Adequate fluid management is a major contributor to improved outcome in patients. Difference in pulse pressure (dPP) has been shown to predict fluid responsiveness reliably in critical care patients. Thus monitoring dPP could be helpful to guide perioperative fluid management. Traditionally, dPP is calculated manually from recorded arterial blood pressure (ABP) charts. The validity and reliability of these values is unknown and might vary because of the different interpretation by different observers. The aim of the study is the assessment of the inter observer variability of manually assessed dPP. This will enable the interpretation of dPP values determined by our automatic respiratory induced blood pressure variation detection (BPV) algorithm.
