Abstract
Of the methods utilized to measure the oxygen saturation of the blood, oximetry is one of the fastest. The purpose of this study was the evaluation of a light reflection oximeter. Per cent oxygen saturation values of arterial blood tonometered with gases of various oxygen concentrations were measured with a light reflection oximeter and compared with results obtained by spectrophotometry analysis and the O2 saturation calculated from the O2 dissociation curve from pO2 and pH data. In the area of greatest clinical importance, between 70% and 90% oxygen saturation, the oximeter results correlated well with those obtained by the other methods. Thus, the light reflection oximeter provides an easy and reliable method to measure the oxygen saturation for clinical evaluation.Keywords
