The process of filtering biological fluids involves removing metabolic waste and excess water from the blood through a semi-permeable membrane. This document covers the physical principles used in Hemodialysis and advanced therapies like Hemodiafiltration .
The specific pressure gradient between the blood compartment and the dialysate that drives the filtration rate. 3. Clinical Applications
Hemofiltration techniques are the primary choice for critical patients in intensive care units.
Effective filtration requires strict monitoring by specialized staff to manage: Ensuring optimal flow for the filter.
Adjusting PTM to prevent membrane rupture or hemolysis. Principios Físicos en Hemodiálisis - Nefrología al día
The process where fluid is extracted from the blood via a pressure gradient across the dialysis membrane to remove retained liquids.
A hybrid technique combining diffusion and convection to increase the clearance of larger "middle molecules" that standard dialysis might miss.
