Dialysis is mainly used to provide artificial restoration of lost kidney function due to renal failure. Kt/V is an established method for determining the adequacy of hemodialysis. K – degree of purification – the ability of the dialyzer to purify the blood from urea; t is the duration of therapy; V is the volume of fluid in the patient.
Calculator of dialysis dose
Kt/V = (-1) * log( Ratio – 0.03 ) + ( ( 4 – 3.5 * Ratio ) ) * ( Ultrafiltrate Volume / Weight ) )
- Ratio = Post BUN/Pre BUN
