ARTERIAL OXYGEN-SATURATION PROFILES IN HEALTHY PRETERM INFANTS

Aim-To construct a reference range of SpO(2) values in healthy preterm infants using a simple data logging device. Methods-Thirty three heal thy preterm infants were monitored for a continuous period of 4 hours at rest using an Ohmeda Biox 3700 E Pulse Oximeter and an electronic d ata logger (Rustrack Ranger). Stored data were downloaded and saved as individual files on a personal computer. Results-The study group medi an and 5th and 95th percentiles were used to construct a cumulative fr equency curve of time against SpO(2) value, representing the normal re ference range of SpO(2) profiles in healthy preterm infants. Conclusio n-Comparison of an infant's SpO(2) profile against this curve may be m ore helpful in guiding supplemental oxygen treatment in that individua l than a figure for a mean SPO2 and its standard deviation.
