Abstract

Extracellular Na+, K+, pH, 2,3-DPG (diphosphoglycerate)

and ATP and the comlex electrical impedance

of whole blood samples from 31 male donors (21 donors form

the training set and 10 donors were used for testing purpose)

were measured on the 0th, 10th and 21st days of storage. Under

storage, the extracellular fluid resistance (Re) and the intracellular

fluid resistance (Ri) decreased progressively with

time; the effective cell membrane capacitance (Cm) has increased.
