Non-invasive monitoring of arterial 02 saturation in newborn infants


Play all audios:

ABSTRACT Ear oximetry is a simple non-invasive method for measurement of arterial O2 saturation (SaO2) in adults and older children. To evaluate the practicability and accuracy of ear


oximetry in newborn infants, we have measured SaO2 in 12 newborns, ages 2.1 days ± 1 (SD) using Biox II-A oximeter and its small ear probe. 15 SaO2 measurements were done during mechanical


ventilation (for HMD, diaphragmatic hernia, sepsis) and compared to actual (CO-OX) and calculated SaO2 from simultaneously obtained arterial blood. Blood pressure was in normal range at the


time of study. Bilirubin and Hb levels were noted. There was excellent correlation between SaO2 measured by ear oximetry and CO-OX values (n=12; r=0.987) and calculated SaO2 (n=13;


r=0.989)(range: 43-99%). SaO2 measured on the scrotum correlated equally well to CO-OX SaO2 (n=6; r=0.979). Bilirubin and Hb levels had no effect on differences between the various SaO2


measurement methods. Ear oximetry is an accurate and practical method for monitoring SaO2 especially in chronic hypoxemia situations during the neonatal period. Transcutaneous PO2 monitoring


will be preferred for preterm infants at risk of hyperoxia. However ear oximetry has the advantages of easier application of the probe with less risk of skin burns, and thus longer


continuous monitoring of SaO2 in hypoxemic newborn infants. ARTICLE PDF AUTHOR INFORMATION AUTHORS AND AFFILIATIONS * University of Manitoba, Children's Hospital, Winnipeg, Manitoba
