In order to study changes in arterial oxygen saturation during anaesthesia without recourse to direct arterial sampling, we have constructed an oximeter similar to that descriptionbed by Wood and Geraci. Construction (rather than importation) was undertaken for reasons of economy. The principles of light transmission and measurement involved in oximetry are discussed briefly and the design of our oximeter is descriptionbed.
