ABSTRACT

Background: Oxygen peripheral saturation (SpO2) is crucial for an adequate management of critically-ill newborns infants (NB). The objective of the present study was to determine SpO2 by pulse oxymetry among healthy term and preterm NBs at an altitude of 2240 m above sea level.
Methods: Observational, cross-sectional and comparative. 218 NBs were prospectively studied between January to April 2004. Eighty nine were term and 128 were preterm. Alpha levels were set at p‹0.05.
Results: The recorded lower value for SpO2 was 88%, and the maximum was 99%. We observed a significant SpO2 difference among the term NB (93.5±2%) and preterm NBs (92.9±2%), p=0.01.
Conclusions: SpO2 in Mexico City’s altitude is on average lower when compared to that observed at sea level. In general with a minimum and maximum values found in our study the SpO2 needed to maintain a critically sick NB with supplementary O2, is suggested. Values should be kept at between 88% and 94% to avoid hypoxemia and hyperoxemia.
