Our aim was to determine predictive values of pulse pressure variation (PPV) and stroke volume variation (SVV) in patients with pneumoperitoneum using LiDCO Rapid haemodynamic monitor. Standardised fluid challenges of colloid were administered to patients undergoing laparoscopic procedures, one fluid ...
3. Using the cursor, find the systolic pressure value for the largest, or maximum, inspiratory waveform, then find the diastolic pressure. Take care to use the systolic and diastolic values on the same form. The difference in these two values...
Validity of Pulse Pressure Variation (PPV) Compared with Stroke Volume Variation (SVV) in Predicting Fluid Responsiveness Objective: Static monitors for assessing the fluid status during major surgeries and in critically ill patients have been gradually replaced by more accura...

BackgroundDuring carotid endarterectomy (CEA), hemodynamic stability and adequate fluid management are crucial to prevent perioperative cerebral stroke, myocardial infarction and hyperperfusion syndrome. Both pulse pressure variation (PPV) and stroke volume variation (SVV), dynamic preload indices derived from...

One explanation for this variation in cut-off values is the site of measurement. In-house analysis by Deltex Medical compared simultaneous measurements of SVV flow (measured centrally by the ODM), SVV pressure (measured from arterial pressure-derived SV), and PPV, and found that SVV flow ...
OBJECTIVE: To compare the diagnostic accuracy of stroke volume variation (SVV) and pulse pressure variation (PPV) in studies that examined both parameters in the same patient population. METHODS: Literature search was conducted in PubMed, EMBASE, CINAHL, and Google Scholar. Receiver operator characte...
ARV: average real variability; CV: coefficient of variation; DMM: difference maximum- minimum; MSC: maximal successive variation. successive change; PP: pulse pressure; ρS: Spearman ρ; SD: standard deviation; SV: observed that correlations between mean PP values and mRS scores were only ...
Pulse pressure variation (PPV) and stroke volume variation (SVV) during mechanical ventilation have been shown to be effective parameters to predict preload responsiveness. Although induced hypertension decreases PPV and SVV, the influences of different vasopressors on PPV and SVV are unknown. 94 patien...
