Abstract

Recently, pulse oximeters have been introduced into nurseries to monitor clinical blood oxygenation. Pulse oximeters measure the oxygen saturation of hemoglobin in pulsed (“arterial”) blood flow. Blood oxygen saturation provides a direct measure of blood oxygenation. However, this measure is variably related to the traditional measure of blood partial pressure of oxygen (PO2) and is affected by factors (e.g., hemoglobin concentration and hemoglobin-oxygen affinity) that may not alter PO2. Therefore, this discussion is written to review principles of blood oxygen transport and to demonstrate from data collected in newborn infants, relationships between pulse oxygen saturation (SpO2) blood oxygen saturation (SaO2) and blood PO2 in a variety of clinical conditions.
