fit-to-fly' test which simulates flying conditions

Last week i had a fit-to-fly' test which simulates flying conditions to see whether or not supplemental oxygen will be needed, i passed the test with a Blood/oxygen average level of 88 while on the test with a mask on for 15 minutes, at normal sea level at rest i am at 92-93. i was so pleased to hear this , i am away next week on a 1.5 hour flight, thought i would just let people know about this test and of course my result :)

Fantastic news for you Guy. You must be really pleased. I have never heard of this fit to fly test. Would you know if it applies to oedema in the brain?

Best wishes

HI Hoggy

Thanks for replie, sorry I cannot answer your replie regarding your condition, my condition is lung problem COPD and recently part of left lung removed, so I struggle with breathlessness, and I needed to know if I had enough oxygen onboard a flight.

Thanks Guy


Well done Guy and thanks for sharing your results with us.I hope you have a lovely holiday.

Best wishes,

All the team at the Roy Castle Helpline
