Abstract
A noninvasive method for continuously determining oxyhemoglobin saturation (02 sat) was compared with measured arterial 02 sat. Fifty-two critically ill infants (71 % Caucasian) were sequentially selected because of their need for arterial oxygen measurement. Concurrent readings were taken from a Nellcor Pulse Oximeter (P.O.) at the time of arterial sampling. Thirty-seven infants had samples from umbilical arterial catheters and fifteen from percutaneous arterial punctures. Arterial O2 sat was measured on a Radiometer OSM-2 Hemoximeter or an instrumentation Laboratory Model 282 CO-Oximeter. The infants were characterized as follows:
Analysis performed by the method of least squares showed the regression line to be
Arterial O2 sat = 22 + (0.72 × P.O. 02 sat)
The Pearson Product-Moment Coefficient (r) was 0.89 with an r-square of 0.79. The standard error of the estimate was 4.6. In conclusion, the Nellcor Pulse Oximeter can reliably determine arterial O2 sat in the critically ill newborn.
