Recording of in-flight SpO2 in a) a 7 month-old term born infant and b) a 9.6 month-old preterm infant (corrected post-natal age 27 weeks). The red dotted line indicates a SpO2 of 85%. The term infant maintained their SpO2 above 90% for the majority of the flight. The SpO2 of the preterm infant decreased to 85–90% once cruising altitude was reached and remained stable for approximately half of the flight before decreasing to <85%. Supplemental oxygen was commenced at this time for the remainder of the flight. Reproduced from Withers (2011) with permission from the publisher.
