Microcirculation in Continuous Venovenous Hemofiltration Patients on the Intensive Care Unit

In patients where fluid is withdrawn from the bloodstream by Continuous Venovenous Hemofiltration (CVVH), the ultrafiltration rate will be calculated for a zero balance. From there, the ultrafiltration steps are performed, after increasing the ultrafiltration rate, the sublingual microcirculation is assessed by sidestream dark field (SDF). The images are subsequently randomly analyzed, and the sublingual microcirculation is expressed as a number, the microvascular flow index (MFI).
