Validating a pre-flight algorithm for predicting in-flight oxygen in patients with interstitial lung disease

Resting P (aO(2)) >9.30 kPa is the best predictor of a pass on a hypoxic challenge test (HCT), suggesting that decisions about the need for a HCT, and therefore the ability to fly without supplemental oxygen, can be made from a blood gas reading in ILD https://bit.ly/40Db0bH.
