Assessment of portable oxygen concentrators in infants undergoing hypoxic challenge testing. A randomised controlled crossover trial

Aim Due to reduced PaO2, aircrafts at cruising altitudes are pressurised to a cabin altitude of 2438 m, equivalent to breathing FiO2 0.15. Portable oxygen concentrators (POCs) are approved for onboard oxygen supply with lack of evidence, especially in infants. We assessed POCs (continuous‐flow cPOC...

Summary:Aim Due to reduced PaO2, aircrafts at cruising altitudes are pressurised to a cabin altitude of 2438 m, equivalent to breathing FiO2 0.15. Portable oxygen concentrators (POCs) are approved for onboard oxygen supply with lack of evidence, especially in infants. We assessed POCs (continuous‐flow cPOC vs. pulsed‐flow pPOC) under simulated altitude conditions performing Hypoxic Challenge Testing (HCT). Methods In a randomised controlled crossover trial, we included patients
