Optical measurement of water content in blood

Abstract

Water as well as wastes is removed from the blood of patients under dialysis treatment. If the quantity of the removed water exceeds the limit by some reasons the probability of dangerous accidents becomes high. Therefore, it is highly desired to monitor the blood status continuously during dialysis treatment. This paper presents some results of a fundamental research of measurement of water content in blood using near infrared spectroscopy and multivariate analysis for the purpose of continuous blood monitoring.
