I felt breathless and had to gasp for breath when descending to Glasgow yesterday on a BA airbus. It was not nice at all. Thankyou for confirming my suspicions it is connected with asthma and, I think borderline Copd.

Thank you so much! Really appreciate it :-D

Great video, I once took an Oximeter on a plane to see this very same thing. I'm a healthy and fit 30 something year old with no known medical issues, however when I try and sleep on long haul flights, I wake up gasping for air. I could never sleep longer than 5 mins and the lack of oxygen would make me really drowsy! I really wanted to sleep but couldn't - It doesn't happen on land, only flying and it feels like mild hypoxia or altitude sickness. There was a suggestion online that Altitude sickness and mild hypoxia seen in climbers can trigger sleep apnea, but have never solved it & still cannot sleep a wink on an overnight plane journey

Thank you for this information I am post covid and also have asthma I have always experienced shortness of breath and chest pressure while flying but never understood it until now again ty

Great Video!!

I've had shortness of breath, chest pain, confusion, and rapid heart beat before too! But I was at sea level. Weird

Amazing video….

I think it will be interesting to see how low/high the impact of hiking in the mountains is in comparison to this study.

For sure! I did a single measurement in Switzerland a while ago, and I did have a decreased SpO2 on the top of that mountain, though I need to perform better measurements to say if the relationship is the same.

Wow really cool experiment thanks!

This is really interesting whenever I used to fly I would experience lightheaded and dizziness on and off throughout the flight and after would feel quite rough and exhausted for a couple of days, even after short flights. I have since been diagnosed with Dysautonomia (POTS), but I am assuming that if my blood oxygen levels were dropping during flight that this most likely contributed to my symptoms.

I had no idea that the cabins weren't pressurized to something closer to ground level (but it makes perfect sense). I suppose anyone who feels these affects when flying might also be more susceptible to altitude sickness if travelling in high-altitude places.

I'd love to see a review of Ps02 accuracy on watches like my Garmin Fenix 5X Plus, will it accurately show the same?

That's awesome! This would explain why I fall asleep on planes easily and I can't concentrate easily. I usually get 93-95% with a pulse oximeter at sea level. Next time I fly I will measure this.

@@TheQuantifiedScientist I am not sure. I have some mild asthma, but asymtomatic atm. My fitbit charge 3 shows cardio score (VO2 Max) of 42-46, which is good to very good for my age. RHR atm is 53 +/-1. However I don't do any sweat inducing exercise currently. Just walking the dog and being a parent. A deeper breath or two will bring it to 95 or 96. Perhaps it is just me not wanting to breathe as much or forgetting to breathe or maybe the trigger for breathing is at a lower level than average. Maybe it will improve with a better exercise regime, not sure.

I wonder what the sp02 meter brand used

At higher pressure the o2 % is the same the partial O2 gaspressure drops which makes it harder for our longs to absorb it

Good 👍

Boeing’s dreamliner actually has a lower cabin pressure at 6000 feet.

Very interesting experiment, it'll be cool to see the long term effect on cabin crew and pilots. Which continuous pulse oximeter would you recommend if I want to measure my SPO2 while sleeping at night?

Indeed, I also wonder how flight crews are affected by all the stuff they go through! They have an environment that is continuously changing. Also, their circadian rhythm must also get screwed up each time they take a long flight. About the SpO2 at night, this I am not the most knowledgable on. I guess the biggest danger is the monitor falling off. I saw that Shervin recently presented this product: kzread.info/dash/bejne/aoyesJWGodnIhtY.html . Though I have no personal experience with it, he mentions something about getting good access to the data. Sorry I cannot be of more help there :-). Have a great day!

Will you be repeating this experiment while doing breathing exercises before, during and after your next flights? I just watched PPPeter's "Climbing Mount Kilimanjaro in Record Time (w/ Wim Hof Method)" KZread video and it was very intriguing.

Great content. I measured CO2 adjusted for pressure, some flights have over 5000 ppm some lower than 1000 ppm CO2 (eqiuvalent to ground level). people can feel discomfort at constant >1000 ppm already. I wonder how this contributes.

Hi Freddy! Thanks for commenting! That is surprising, since from what I understand they generally pump in a lot of (warmed up) fresh air from outside, which should have normal levels of oxygen. Any idea what might cause this difference you see between flights? Just a lack of pumping in fresh air in some airlines? How did you measure it?

Have there been any studies on how the lower blood oxygen levels impact people who have existing hypoxic/anoxic injuries of the brain? I ask as I have previously suffered Decompression Sickness ~ Type II Cerebral. Complicated by symptoms not originally treated & more than one event, plus an international flight further complicated by delayed hyperbaric treatment, which left me with an Acquired Brain Injury. Approximately 14 years later I had 2 international flights, one of around 6 hours that also involved higher elevation levels than planned due to severe turbulence on the way home, the 2nd international flight was 10 hours. It was after these flights that I became aware of symptoms that reminded me of those I suffered with my DCS. But this made no sense as I could not have the bends from a commercial flight. After doctor visits & following up with the medical team that treated my original injury, I was informed that as I had an exisiting acquired brain injury there was every chance my injury had been exacerbated by the lower oxygen saturation levels. So the symptoms I had been experiencing were very similar & not my imagination, which is what I had initially thought. But there is little to no research out there about this, therefore it is an unknown until too late.

So interesting! You've got a new subscriber:)

How can we minimize the impacts of lower oxygen levels & low humidity in a plane? Breath work, certain cardio activities, could they make flight travel less impactful on our bodies? Can we give ourselves oxygen or somehow increase humidity around our seat? Also are you wearing 2 Oura Rings?!z

@TheQuantifiedScientist

Hi Shervin! Thanks for your comment, all very good questions. So, first, having extra oxygen is theoretically possible, and airlines will provide it for patients with certain lung conditions (as far as I am aware). However, I expect healthy people will not be allowed to take this in an aircraft. I guess the most important thing to do about the humidity is drinking a lot of water, since you want to make sure your body retains enough water. I expect cardio activities might actually lower your SpO2 on the short term, though I think in the experiment I mentioned they had people exercise and it did not seem to have major effects. Breath work I am not sure about, though it might be tough to keep those up continuously/intermittently the whole flight, and the effects of the lower air pressure seem to kick in rather fast. So to answer your general question: what can we do about it? Well, I am not sure... The best/easiest thing would be if airlines structurally increase air pressure to 6000ft. However, other people have more knowledge about this than I do :-) Thanks again for your great questions! Have a great day!

Living in the mountains may impact this positive. The body has a higher amount of red bloodcells in cause of the inefficient oxygenconsumption. The SpO2 rate is also low, but effect of sicknesses are mostly not existant.

To minimize the impact, drink water and breathwork with fully inhale and just letting go at the exhale, and no pause nor retention in breathing, should work. It's a derivative from the Wim Hof Method breathing itself derivated from pranayama.

Do you think that if a person has a portable oxygen concentrator for a long-haul flight, the levels of oxygen would remain steadily throughout? I trying to find information if the passenger is given oxygen the whole flight, whether it is 1 hour or 8 hours, would the drop of oxygen saturation be so significant or would it as if the passenger is on the ground? If the person has oxygen, could it be possible that the air pressure affect oxygen saturation even with the oxygen on? So many questions I know, but I'd appreciate your insight.

How are you sir I want to know that oxygen level of aeroplane is same like ground level maintan when plane flying high attitude 41000 please explain little bit sir we can breath easily there

Hi Moni, sounds like you are having a tough time, I hope it resolves itself soon. I am no medical doctor, so I don't want to speculate what could cause this. I cannot imagine what could make SpO2 drop that drastically, that quickly, so please consult your doctors and show them what you described. All the best!
