We included patients admitted due to an asthma attack and planned to take a trip by plane after that period. Epidemiological and clinical data were recorded. Informed consent was obtained. During the first 24 hours after oxygen therapy was finished a spirometry and pre-flight hypoxic test was performed. Patients were selected as {\textquotedblleft}fit to fly{\textquotedblright} if SatO2 remained above 90\%.Results: We included a total of 21 patients (13 male). The mean age was 7.3 years (2.5-12.2). The means of the different clinical characteristics were: hospital stay 5.2 (3-10), oxygen therapy 4.1 days (1-9), maximum FiO2 0.4 (0.28 to 1, FEV1 88\% (42-130), FVC 91\% (53.7 to 148) FEF50 62\% (33.7-117) and pre-test SatO2 95.5\% (92 - 99).17 patients (81\%) passed the test during the first 24 hours after removing the O2, and the remaining 4 (19\%) within the next 24. No significant correlation was found between FEV1 and the minimum SatO2 during the test. Any previous data (including previous SatO2) were related with the test results.Conclusions: All the children hospitalized for asthma exacerbation pass the hypoxia test 48h after removing the oxygen so we conclude that concerning oxygen they could fly safely after this period.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/42/Suppl_57/P1131}, eprint = {https://erj.ersjournals.com/content/42/Suppl_57/P1131.full.pdf}, journal = {European Respiratory Journal} }
