Long haul flying

[sinclair61]

Hi

I just took a 11 hour flight yesterday. My GP said I was find to fly beforehand without oxygen.

However, at certain brief times during the flight my oxygen level dropped to 92/93 and would get mildly SOB and would start PLB. This would last for 5 minutes at a time and probably happened 3 times. Oxygen never dropped below 90. The rest of the flight my sats around 98 and had no issues.

Anyone have any ideas why it would happen briefly on the flight and was fine for the majority of it? My sats never go below 95 on land, even when exercising.

Thanks

Hi

High altitude flying results in a drop in oxygen from 21% to 18% and as low as 15%.

Hi,

I understand that - hence the need for oxygen.

By what I wanted to know will a drop to 93 happen to most people on a long haul flight as they change cabin pressure or only those with respiratory diseases?

Does that mild drop mean that I most likely need oxygen when flying?

Thanks

Sinclair

Hi

Some reading matter for you may explain better. The way of knowing if you need inflight oxygen is to conduct a high altitude test.

You might like to consider ambulatory o2 if you are to fly long distance frequently and could mention your observations to your gp/respiratory consultant.Stone has given you the medical facts with regard altitude and flying but at the moment your observations and reactions do not appear to be to alarming something to consider for the future,My own resting stats are 90% and drop to the low 80's after 15 mins of cabin pressure on air,though i am stage 4 emphysema with an fev of 22%.............good luck in the future,,skis and scruffy

I have been told not to fly as even if I have a test to go out I might not be well enough to return. I could not even get up Mount Vesuvius when I was fitter than now and could fly.

Be Well

I've a look up, it appears that everyone drops around five percent. From where I start that would not be good

[O2Trees]

Well I dont know if you have any specific condition which means sats dropping as you have is dangerous, but I would be thrilled if my sats only dropped that far. If mine were like that I wouldn't consider having supplementary oxygen for a flight. But if you are worried speak to your GP.

No surprise your sinus infection got worse on an 11 hour flight.,

Totally agree with O2Trees above - wish I had such great says as yoursx

Like O2 trees said, even people with normal healthy lungs drop their sats when flying. When I was on a four hour flight in the summer my seat mate who is very healthy, tried my oxymeter and their levels were at 93. They felt no different.

My sats dropped to 85 and I upped my oxygen then. On land I am usually between 96 and 98 if I'm not walking.

Hi Cas

Yes I am not allowed to fly..awful to say but the pressure can burst cysts..

So I have taken to train journeys..I’m not a boat cruise type of girl, and I don’t drive! I watch beautiful geographic programmes and dream on..xx

I'm sorry Fran. But maybe one day.... we can dream all sorts of things. There wonderful thing about dreaming is no one can tell us what to dream. 😁🎶

Have a lovely weekend.
