Abstract An optical blood hydration monitor for use with extracorporeal haemodialysis circuits is described. Studies in five stable haemodialysis patients demonstrate good correlations between measured blood water, haemoglobin concentration and optical attenuation during ultrafiltration. There are no significant errors introduced as a result of a changing extracorporeal circuit pressure and errors resulting from a changing state of oxygenation of haemoglobin are small. Changes in blood volume effected by ultrafiltration may be deduced if it is assumed that these are due solely to shifts of water into or out of the vascular compartment.
