Use of a dynamic method in calibration of dye-dilution curves during cardiac surgery.

Abstract

A simplified dynamic method of calibration for dye-dilution curves is described. The method involves appropriate matching of the fluid volume in the mixing chamber, the blood withdrawal rate, and the calibration dose of dye. It was used to compare the observed versus calibrated pump output of a heart-lung machine with individual dye-dilution curves obtained… (More)
