Abstract

Oxygen transport in blood depends on oxygen partial pressure (PaO2), oxygen saturation (SaO2), hemoglobin content (Hb) and cardiac output (CO). At least SaO2 and Hb-content as well as CO should be known to achieve reliable insights into tissue oxygen supply of patients in intensive care and during anesthesia. Methods for cardiac output and saturation measurements have been available for some time but there exists so far no method to measure the Hb-content continuously in vivo as well as in vitro.
