Hi,i first had the test after a stay in intensive care as we thought a holiday in the sun would do me good,I'd flown many times before no problem ,but consultant asked me to have the test ,and what happens is ,,,,,
for twenty minutes you sit with a mask on that simulates the pressure of a plane,and as long as your oxygen levels don't drop too low then it's ok ,but if they DO ,,,,,drop sorry I can't remember the number but I think it's ,,,then you sit for a further twenty minutes with the mask AND oxygen and as long as your level doesn't drop consistently below,I think ,,90,,,then it's ok ,
sorry about not being sure of the numbers ,,,,,,during the last two tests I had sadly after just a FEW minutes without the oxygen ,,,I could tell that my levels were drastically dropping ,,,,and the feeling was terrible,
My oxygen levels are good usually around 94/93,
if in doubt ,,,,,ask your hubby's consultant or GP if he advises he has an inflight test ,
please don't take my word on my numbers ,,,as it's sometime since I last did the test ( I don't bother now. ) ,,,I hope you and your hubby continue to have holidays in the sun ,,,,,,oh I'm afraid of water ,,,,so a cruise us out ,,,
