WebDialysis has two main functions: solute clearance (waste removal) and ultrafiltration (volume removal). The mnemonic “AEIOU” includes the major indications for dialysis: A cidosis: if severe (pH <7.2) and refractory to HCO3 OR unable to give HCO3 due to volume overload. E lectrolytes: usually hyperkalemia >6.5mmol/L OR lower with ECG changes. WebMay 25, 2016 · Continuous veno-venous haemofiltration (CVVH) uses the principles of ultrafiltration, hydrostatic pressure and convection to remove both fluid and solutes from the patient.

WebMar 23, 2024 · What is ultrafiltration in CRRT? ULTRAFILTRATION. Ultrafiltration is the movement of water across a semi-permeable membrane because of a pressure gradient (hydrostatic, osmotic or oncotic). The increased blood pressure in the glomerulus creates a favourable driving pressure to force water across the glomerular membrane. WebThe Continuous Veno-Venous Hemofiltration (CVVH) program is a short term treatment used in ICU patients with acute or chronic renal failure. Usually, hemodialysis is typically done for patients with kidney failure. However, if the patient has low blood pressure or other contraindicators to hemodialysis, CVVH may be a necessary alternative.
