Yes Carrier....what your expert says is correct...my INR reading was just so unstable...it was difficult to maintain @ 2.5...
reason is my diet....I like a drink and my choice is red wine....the foods I eat is another factor...especailly foods that contain vitamin K....throws everything out of balance while on warfarin....
The FAA in the States will allow you to fly while on Warfarin...but that is on an application and an approval...
CAA is considering its stance, and maybe will go the FAA way....at the moment CASA in Australia will not alow you to fly as the CAA in the U.K.....
Its all to do with the lack of O2 and dehydration....and as Long Haul is becoming more frequent with the A-380 etc....this will become even more prevalent...
As I said before...WATER is the key....
