Extracorporeal Membrane Oxygenation Indication for CRRT:
Renal Replacement: - Hyperkalemia - Acidemia - Pulmonary Edema - Regulation of acid - base and electrolyte imbalances
Renal Support: - Fluid removal in CHF - Cytokine manipulation in sepsis - Treatment of respiratory acidosis in ARDS - Fluid management in multi system organ failure CRRT
MODES OF THERAPY:
SCUF - Slow continuous ultrafiltration. Primary goal is volume removal.
CVVH - Continuous Veno Venous Hemofiltration. Primary goal is to achieve small, medium and large molecule clearance (convective) and remove patient fluid.
CVVHD - Continuous VenoVenous Hemodialysis. Primary goal is to achieve small molecule clearance (diffusive) and remove patient fluid.
CVVHDF - Continuous Venovenous Hemodiafiltration. Primary goal is to achieve small, medium and large molecule clearance (convection and diffusion) and remove patient fluid.
Hemofilter structure and function.
Diffusion - dialysis uses a semipermeable membrane for selected diffusion. Movement of Solutes from an area of higher concentration to an area of lower concentration.
