[Non-invasive determination of oxygen saturation with the oxygenmet pulse wave oximeter on fingers, metacarpus and wrist of infants. Comparison with the oxygen saturation calculated from the pH and pO2 of the blood gas analysis (author's transl)]

Abstract

Oxygen saturation was determined non-invasively with the oxygenmet pulse wave oximeter 1471 and mathematically from the pH and pO2 of the blood gas analysis. The determination of the oxygen saturation by the aid of the oximetric method was carried out on fingers, metacarpus and wrist of 80 infants (male = 44, female = 36 - ages: 1 day - 1 year and 8 months). Blood gas analysis was done just behind the oximetric analysis and oxygen saturation was calculated from the pH and pO2. The comparison of the oxygen saturations determined non-invasively on fingers, metacarpus and wrist among themselves, showed no statistical significant differences. Also no statistical significant differences were observed between the results obtained with the pulse wave oximeter and the results calculated from the blood gas analysis. The comparison of the oxygen saturations determined with the oxygenmet oximeter (mean of fingers, metacarpus, wrist) with the oxygen saturations calculated from the blood gas analysis showed a very close correlation. The correlation coefficient was 0.930.
