WARNING on the DANGERS of HYPOXIA

[@PrinceThomas00Ke]

Nice educative flight video 🎉🎉🎉🎉

[@GBelly-tf9sq]

I went through a day of training at Wright-Patterson AFB in the 80’s. The altitude chamber was most interesting. They did a slow altitude climb to 20,000 feet with our masks off. They gave us a pencil and pad and had us write our names as we ascended. It really sneaks up on you. I had written my name at 5 different altitudes, the last one being at 20k. The first few were legible, the last two were complete gibberish. Got back on the oxygen at 20k and they started descending. Then they did a rapid decompression from a cabin altitude of 8000 ft. That was impressive as the bang and the condensation was quite alarming. They also put us through a simple rig called the vertigon to experience vertigo. That was the most poignant training I’ve ever received. Hypoxia and vertigo are deadly killers. Every pilot should be required to do this type of training. Being able to pick up on the signs are critical to one’s survival, as well as your passengers.

Re hypoxia and O2 use: I was flying from Seattle back to my home base in the Los Angeles area. It was a perfectly clear day and evening, and on my final leg from northern California, I was at 11,500' (I liked to fly high just to avoid any issues), and it was late in the evening, after dark. I was using a portable oxygen system with nasal cannula and an oxygen metering system (it would sense a breath via back pressure and feed oxygen, and the oxygen pulse was also based on ambient pressure, very nice system that conserved O2 for long flights). At the time, it was only possible to get a portable pulse ox with a prescription, and they weren't cheap, like they are now, so I didn't have one. I had always heard that one of the detectable differences of hypoxia was that your night vision suffers, so I devised a test as I was passing east of the Bay Area: I would take off the oxygen for 10 minutes, then put it back on and see if I could tell the difference. I did exactly that, and I noted as I checked my clock for the 10 minutes to pass that it seemed the city lights from the Bay Area, easily visible off in the distance, seemed to dim. I put the O2 back on at the end of the time, and took a couple breaths. I was startled at how much the lights appeared to brighten with the hits of O2! It was a dramatic difference. I understand that your eyes require a lot of O2 to function properly and they're one of the first things to suffer when you become hypoxic. I also felt that with the long flight, it kept me feeling less tired than I would have been without the O2. I guess my point is that O2 has positive benefits even without obvious mental deficits. My policy became to use the O2 for sustained flight over 7000' (I might not if I was just popping up quickly over a ridge).🙂

[@anonymousanonymous-ok3nn]

Flying over north of the LA area is always tricky at night. I usually stay at MEA via the federal airways even for VFR. The MEA of the airways via the Gorman VOR I believe is 11000. One night I was back from KSMO to the Bay Area at night at 11500 without oxygen. It had moonlight at that night but I couldn’t see anything around but my PFD. I realized it was hypoxia so after passing GMN I dropped down to 6000. I immediately realized my vision and judgement got better as I was descending. The other occurrence was a trip from Rapid City, SD to the Bay Area. I was cruising at 10500 over Wyoming. The flight was sleepy and dizzy. I had to keep listening to Spotify and dance my wings along with the beats left and right to keep me awake. If I engage the AP I’m afraid I would fall asleep in seconds. My wife wasn’t comfortable neither so we diverted to Battle Mountain in Nevada. All I was thinking was just to put the plane down. As I was descending through 8000, I suddenly felt awake and a sense of in-control. It’s just like in a math class you try not to fall asleep then all of a sudden your drool drops on the desk and you wake up. Despite there are a couple of sand storms in the valley, including one right in downwind and another on final, and wind shear all over the place, 9000 ft density altitude, I felt ready for the landing and any go-around procedures. I greased the landing. Definitely going to invest an oxygen system for such long XCs.

[@ibluap]

Please, we are created to breathe oxygen; however an excessive dosage has a negative side too. Excessive oxygenation can drive to rise oxidative processes all over the body and just as the lack of oxygen can impair vision, excess oxygenation can damage the eyeballs, especially after long time abuse; so, I would connect me to oxygen ONLY when partial pressure is under normal range; that is, over 10,000 ft, short or long travels included. Remember: oxygen dependant people are not in danger only because their natural system is impaired and at the end the final sum is a normal tissues oxygenation. If your system is healthy, breathing an enriched oxygen atmosphere will mean an overdosage and if you use oxygen under the requested altitude, you will add flight hours of overdose and perjuidice your health.

[@sthomas6369]

@@ibluap I don’t think you understand how the oxygen system I was using (and briefly discussed) works. The system does NOT just turn on a constant flow of oxygen to the user. It is specifically designed for pilots, not medical use. It METERS the oxygen output, by sensing the cabin pressure of the aircraft (unpressurized), and delivers a short pulse of oxygen when it senses back pressure from the user taking a breath (not unlike how some CPAP machines work as well, except obviously they’re not delivering O2). The duration of the pulse and therefore the amount of O2 delivered decreases as the sensed pressure altitude decreases, and (obviously increases as it increases). So at a lower altitude, it’s delivering hardly any O2 at all - it is practical to keep wearing it all the way down to landing so as to avoid dealing with the equipment during approach, it just delivers almost nothing as you get lower (of course unless your airport is at high altitude). The system also has a maximum practical altitude for use with cannulae, at which point a mask is to be used. I never flew remotely close to that though. I have personally used it up to 15,500 ft in my unpressurized single engine Cessna, and the pulses get much longer at such an altitude. As I said, I would use it for long duration flights above 7000ft. I don’t consider an hour flight where I maxed out at 7000ft to be “long duration”. I’m talking about several hours (my airplane had a practical endurance of about 5 hours with reserve, and my bladder less than that). Practically most of the use I got with the oxygen system was probably flying 9500-12500 ft and flights of 3 hours. Flying on an IFR flight plan out of the LA basin would usually guarantee that MEA and I never wanted to be horsing around with the O2 system while in IMC, so I’d put it on early and take it off after landing. Certainly there can be issues with hyper-oxygenation, but this really isn’t a situation where that’s likely or possible.

Same here, although not a drinker, my year old son and I watch ryans videos for a nighttime "cooldown" for the day. He is fascinated with anything with an engine and it the way Ryan does his videos, it puts him in a calm mood for bed. I just enjoy it just as much to unwind and relax to a long day!

Very cool again all your videos are cool. I’m glad to see you’re wearing oxygen I got hypoxia one time I left Phoenix flew to Flagstaff Arizona spent the night. keep in mind I’m not used to being at 7500 foot so I spent the night get up the next morning I was in a turbo 206 flew right up to 12,500 I was doing pilotage I had GPS I had my VOR‘s. Everything was was great a minute later I felt lightheaded and I asked my friend who was in the copilot seat if he felt anything and he said no and then about 20 seconds later he goes oh I feel it then nothing made sense. My landmarks outside weren’t there the GPS wasn’t right. The VOR’s weren’t right. Nothing made sense, I set a 700 footer sent on the auto pilot and landed in Page Arizona, which was my destination. I picked up my girlfriend and then flew back to Phoenix and I didn’t feel right for two days. I was not wearing oxygen because I was only up at that altitude for about 15 or 20 minutes and then I was going to descend again, by the way different subject, it would be cool if you did a little tutorial on how you do your videos like how do you get that little airplane on the screen? Are you screen record recording your iPad the whole time does that affect the performance of the iPad with your flight, etc.

I was being transported by RFDS a few years ago and had an oxymeter on my finger. It was quite interesting to watch my levels fall at altitude. A bit of controlled breathing allowed me to bring it back up to 98% or so.

[@CaptTony107]

New to the channel and feel just as stupid as I did at 18 about being able to fly an airplane! I know it's all about time in the seat, but I have always been a bit intimidated by the confident Alpha male personalities many pilots seem to have. It seems a prerequisite and while I did put myself "out there" in my career, I never had the balls (or smarts) to put it "up there"! So I'll be content to fly vicariously through you and I really do enjoy every minute of it. Although I still don't understand half of it, and am too old to learn flight sim training w/o a little help; and other than Top Gun, I have never landed a plane safely other than an occasional touchdown on that sim carrier!🙂 Thx, and Godspeed, for all you do.

[@andrewplumb6544]

Don't undersell yourself. As PPL of 40 years I can tell you that many pilots are just people who are more likely to say yes than no to fresh opportunities

[@BluBlade-k7b]

Leaving the Grand Canyon heading back to Mesa the 172 was climbing , slowly . Very clear day and light winds in January . We were already at 6,500 , a few minutes later we were passing 10K . Nothing was changing , all was good . I was talking to my pax and getting no response , they were sleeping . Then I noticed we were passing 13500 . I was ok but I started decending slowly , about 9500 they were awake . i never told them how high we were .

[@philsal17]

Really nice to see that those old instrument skills can come back. You've been away from this type of flying for a long time and yet, the skills are still there. You fly beautifully. Thanks for sharing with us the choices and the factors involved in your decision making.

[@caiolinnertel8777]

Great video. I use a pulse Ox too, even though I’m pressurized (C414A) when I fly above FL200. My cabin stays below 6,000 up to FL230. Typical airliners, like the old B737 I flew generally maxed the cabin out at 8,000 feet. The B787, due to the carbon composite cabin maintains at or below 6,000 feet which is really cool. Not really pumping in O2, but compressed bread air, through A/C packs (compressed air is hot). So, say if one of our A/C packs was out (in the B737) we couldn’t go above FL250. I have to say IFR there is SO weird, even the phraseology isn’t ICAO which I found odd. “Line up” and no “Wait” seems odd. Then again, ya’ll don’t have the same traffic volume we do in the USA and Europe.

[@MissionaryBushPilot]

Yeah, it's suppose to be ICAO, but....yeah. From what i was told by one of the controllers, they got 2 months of training.

[@AlaskaOutdoors]

Recommending the O2 sensor probably just saved a few lives. I used to live in big bear California for a construction job being a Born and Raised Alaskan I’m used to high elevations but at sustained elevation above 8000 feet up there. I definitely noticed a difference in my behavior and thinking. I also was in an aircraft with my uncle when I was younger he had O2 and said see how long you can go without it and if you can put your O2 back on once you feel drunk. Needless to say he put my O2 sensor on for me. I was having too good of a time if I was flying that airplane I would’ve been dead for sure.

[@arturoeugster7228]

I flew out of LSZH (1400 ft elevation) giving biannual reviews to expatriots living and flying there, about a few days later, flew the Pilatus Porter of the president García Mesa 'militar 009' out of LPB, elevation 13600 ft to the Salar de Uyuni, elevation 12001 ft to Oruro and back to LPB always above 15000 ft density altitude, (TAS is 1.25 times IAS) there was no need , nor were there provisions for oxygen in that aircraft. What is important, medically is the O2 content in the volume of air in your lungs, not the pressure. At the density altitude of 15000 feet the O2 content is 64% of sealevel content per m³ (0.64 × 0.21 × 1.225 kg/m³). In Switzerland there are glider operating areas (Wolkenflug Zonen) where you can fly to altitude in gliders to gain your altitude badges of 3000 and 5000 meter altitude gain. (5000m = 16400 ft) So we carried a blue bottle of oxygen, built into the sailplane . That is a limited amount, so you had to be careful not to waste oxygen. To understand the ramifications of hypoxia we used the pressure chamber of the University of Zürich to measure and observe and test the effects at different altitudes precisely up to 7000 meters concentrating on the calculations needed in flght, the result was that below 5000 m we did not use O2 but always turned it on passing 5000 m, one effect is euphoria which causes pilots to delay oxygen supplementing, so this firm safe altitude was decided on by the doctor in charge : conserve O2 below 5000m, use oxygen above 5000 m. that rule was used in our University flying club. This measure has proved itself, because it is precise for pilots not used to altitude but not in the habit of consuming alcohol.

[@GokouZWAR]

By the way Ryan, the Apple Watch has a blood oxygen checker built into the watch. I’d recommend you try one, cuz that will actively monitor your blood oxygen. I think you can setup notifications if it gets low.

The problem with the oxygen "whiskers" is that to obtain the adequate oxygen dosage you must not forget breathing by the nose. If you don't, you even can receive some dosage by flow reflexion in the rear pharynx, however it is not a secure and steady dosage. Many people who speaks a lot, is automatically used to breathe by the mouth between words... beware! Also, if you are in a cold or suffering an allergic rhinitis (apart of the baro-otitis), you can unwittingly start breathing by the mouth. I guess there's got to be a safer oxygen intake for pilots.

a high reading, close to 100 means your blood has lots of oxygen in it

Many sensors actually measure colour and because CO poisoning increases the redness, fail to detect low oxygen due to carbon monoxide poisoning.
