Abstract

Measurement of blood oxygen and carbon dioxide tensions is routinely employed to assist clinicians in patient evaluation and treatment. This method necessitates either arterial or venous puncture or indwelling hollow catheter to obtain the sample. Ex vivo Clark Polarographic O2 and the Severinghaus CO2 electrodes are the actual measuring devices. Many attempts have been made at continuous analysis using the O2 and CO2 electrodes with specially designed flow through cuvettes or miniature catheter tip electrodes. Most of these methods suffer from lack of repeatability and/or loss or linearity.
