Comparative Study[Accuracy of measurements of Kontrol 7840, Nellcor N200 and Radiometer OX13 pulse oximeters in infants and young children].
Comparative validation studies of pulse oximeters from different manufacturers have predominantly been performed in adult patients. However, due to differences in the patient-sensor interface, the results from those studies may not be transferable to the paediatric population. We therefore performed 123 simultaneous measurements (37 patients) of transcutaneous O2-saturation (StcO2) from 3 pulse oximeters and compared these with the arterial O2-saturation (SaO2) from a co-oximeter (Radiometer OSM 3). ⋯ The corresponding 95% intervals were -7.4(-) + 9.6%, -5.7(-) + 4.3% and -7.0(-) + 6.3% for the Kontron, Nellcor and Radiometer instrument, respectively. These results demonstrate that neither of the 3 instruments systematically under- or overestimated SaO2. However, there were differences in precision, particularly in the low range of SaO2.
