Abstract
Official abstract text for this publication.
A method of predicting serum potassium concentrations in a patient during hemodialysis includes measuring serum potassium concentrations of the patient over a hemodialysis treatment session time and an ultrafiltration rate calculated by a difference between pre- and post-dialytic body weight of the patient during an initial hemodialysis treatment session divided by a total treatment time of the treatment session and estimating a potassium mobilization clearance and a pre-dialysis distribution volume of potassium for the patient. Serum potassium concentrations of the patient can then be predicted at any time during any hemodialysis treatment session with the estimated potassium mobilization clearance and pre-dialysis distribution volume of potassium of the patient.
First claim
Opening claim text (preview).
The invention is claimed as follows: 1. A method of predicting serum potassium concentrations in a patient during hemodialysis and determining a treatment regimen based thereon, the method comprising: measuring serum potassium concentrations (“C”) of the patient over a hemodialysis treatment session time and an ultrafiltration rate (“Q UF ”) calculated by a difference between pre- and post-dialytic body weight of the patient during an initial hemodialysis treatment session divided by a total treatment time of the treatment session; estimating K M and V PRE for the patient using a non-linear least squares fitting to the equations: C ( t ) = C PRE [ K M + DC D / C PRE K M + K R + D - Q UF + [ 1 - K M + DC D / C PRE K M + K R + D - Q UF ] × [ V ( t ) V PRE ] K M + K R + D - Q UF Q UF ] , and ( eqn . 1 - A ) C ( T ) = C PRE -
