Hypoxic Challenge Testing (HCT) is the recommended method for inflight hypoxia risk assessment. Onboard oxygen administration remains controversial. The Federal Aviation Administration approved portable oxygen concentrators (POCs) for onboard oxygen supply but there is lack of evidence about the use, especially in children. The aim of our study is to establish the effectiveness and safety of POCs in infants undergoing HCT.
