  • Title: Arterial oxygen saturation profiles in healthy preterm infants.
    Author: Ng A, Subhedar N, Primhak RA, Shaw NJ.
    Journal: Arch Dis Child Fetal Neonatal Ed; 1998 Jul; 79(1):F64-6. PubMed ID: 9797629.
    Abstract:
    AIM: To construct a reference range of SpO2 values in healthy preterm infants using a simple data logging device. METHODS: Thirty three healthy preterm infants were monitored for a continuous period of 4 hours at rest using an Ohmeda Biox 3700 E Pulse Oximeter and an electronic data logger (Rustrack Ranger). Stored data were downloaded and saved as individual files on a personal computer. RESULTS: The study group median and 5th and 95th percentiles were used to construct a cumulative frequency curve of time against SpO2 value, representing the normal reference range of SpO2 profiles in healthy preterm infants. CONCLUSION: Comparison of an infant's SpO2 profile against this curve may be more helpful in guiding supplemental oxygen treatment in that individual than a figure for a mean SPO2 and its standard deviation.
