An in vitro system was developed capable of testing the accuracy and reproducibility of pulse oximeter readings. The pulse oximeter probe receives signals through a pulsating blood cuvette. The development of the design of the cuvette is described. Using the final design (or 'model finger'), a comparison is made between readings from a Datex Satlite pulse oximeter (SpO2) and saturation values obtained by use of a multiwavelength bench oximeter (SaO2). Linear regression analysis of the data gives SpO2=0·88 SaO2+11·2 (r=0·979, p<0·001).
