Amaizing and live saving interview Martin. No matter how much we know about oxygen and carbon monoxide, there is always more to learn, especially from people like Dr. BLue. Thank you for your work.
Thanks, Armen.

This was a very interesting conversation with a lot of valuable information. As always thanks Martin for taking the time to bring us these great videos.
Glad you found it useful, Kevin.

I remember Blakesburg! I flew to the antique aircraft gathering a few times. As I recall, it was a very short, grass field. It looks like it was a beautiful day for you and the doctor. I need to get a detector for my Archer, and a portable oxygen tank. If you file IFR out here, you better have oxygen. I got carbon monoxide poisoning when I was a young man. I road with a friend in his corvette from Florida to Iowa. I had a headache for days... Fly safe, Martin! Rick
Glad nothing worse happened on that trip, Rick.

Thanks Martin!
Great review even for those of us in the medical profession. I’ve done the NASA pressure chamber coarse, the first thing I noticed at 20,000’+ was changes in my Rods and Cones making viewed imaged colors less bright then to black and white.
The review of carbon monoxide was exceptional and answered some of the questions why my monitor reads 10 ppm during taxing during the summer.
Thanks, Bill - glad you enjoyed this discussion.

Excellent video. Years ago when I had a Turbo Saratoga SP I routinely flew at 10 or 11 thousand feet to get above the bulk of the traffic. But o noticed on long flights I would end up with a slight headache. I eventually worked out it was the onset of mild hypoxia and started using low levels of oxygen via a cannula and was no longer feeling tired or have a headache after a long flight.
I hadn’t heard the idea of taking pulse ox on the ground and using O2 when it dropped 5 points. That makes a lot of sense to me and I will start doing that.
Yes, we can all benefit from more regular use of oxygen
- Martin
What an awesome interview thanks for doing it! Learning about the five percentage points and 10 percentage points makes for oxygen makes much more sense than an arbitrary altitude. Martin you are awesome!
Glad you found this video helpful, Shane.

Excellent information, Thank you !
My pleasure!
- Martin
Wow, learned so much in this one thank you. Especially about the 12,500 reason.
Glad you found it helpful!

Thanks for the interview, Martin - it was excellent. I love these interviews and I hope you keep doing them with other aviation experts like you have in the past.
As a data point, I have an Inogen One G5 oxygen concentrator and it's awesome. I mainly fly solo - like 90% of all pilots - and fly in the mountains, and like to cruise at 8k+. It has a battery that lasts 6 hours, and has a 12v cigar lighter charger that takes about 3 amps. I keep it plugged in since I have the power, but even if I didn't, 6 hours is a lot. New they are expensive and hard to get, but they come up used regularly. Something to consider, since they are so simple to use, rugged, portable, reliable, and will keep your brain clear when you fly.
That's good to know - thank you for sharing. Would you happen to know if the Inogen G5 can handle 28V power? That's what my Bonanza has on the cigar lighter port.

@@martinpauly I'll check next time I'm at the hangar and update you.
@@dermick Thank you!
Probably the most important video you have shared to date. It's amazing that the dangers of gas stoves in houses and alcohol as a carcinogen got media attention this week. Should we have CO monitors in our gas powered cars and trucks?
Thanks, Don.
- Martin
Great video on a much needed topic of understanding among the GA community 👍. Definitely a potential life saver episode 👍
Thanks, Justin.
- Martin
Wow, medical advice based on scientific data gathering! Thank you Dr. Blue.
Very interesting Martin. I have a PA28 and I don't have any carbon monoxide detection. I will now!!! Thank you
Good on you - hopefully you'll never need it, but it's an inexpensive insurance policy.
- Martin
Excellent interview. Everything Dr. Blue says is correct. Interestingly, cyanosis is a term used when a person turns blue when they have elevated relative CO2 levels and can be associated with hypoxia. So, Dr. Blue's name is appropriate 🤣. Frank S. Rosenbloom, MD
Thank you for the feedback, Sir.

Great video Martin definitely very informative.
Thumbs up before watching your clip! Greetings from Germany, thank you for your great content!
Thank, Chris.
- Martin
Great info! Thank you.
Great video! This answered the questions I've been asking about!! Thank you!
Thank you - glad you found it useful.
- Martin
The best non-flying video yet! Thanks!
Thank you, Michael.
- Martin
Great interview and video. Thank you again
Thank you, Kevin.
- Martin
Excellent information. Thanks so much for sharing this discussion.
You are very welcome!
- Martin
Very informative. Good interview Martin.
Thanks - glad you enjoyed it!

Martin… thanks for the great video. One thing I was hoping you would ask Dr. Blue about was the use of the Oxygen Boost cans you can buy via Amazon. I am wondering how effective those would be to get that shot of oxygen while at altitude or before a landing after a long flight.
Thank you, Richard. Maybe Dr. Blue will see your question here and chime in.
- Martin
I guess I’ll be finding another detector instead of my Sentry.
Thanks Martin for this very interesting clip, the 5 plus 10 point rule I didn’t know until now! For me very important, because I’m always concerned about my ground saturation , which is never 99. Für Dich beste Grüße aus Berlin und bitte mach weiter so😊
Freut mich, dass es Dir gefallen hat. Herzliche Grüsse in die Hauptstadt!
- Martin
Excellent video - thank you both!!
Hi James!!!!! Hope you're doing well!. Osh 2023?
Thank you, James.
- Martin
Great video Martin. Above 6k I use oxygen now, especially on long cross countries. It’s cheap insurance. Sensitivity to altitude is not a linear nor is it even repeatable. You could be fine at 10k one day, then not so fine the next. Did you get caught up in the Conti 550 counterweight debacle?
Thanks!
Fortunately I am not affected by the Continental AD. I feel sorry for the many airplane owners who are.
- Martin
Martin this is an absolutely excellent safety video. Would you be able to contact Dr. Martin and post the carbon monoxide units he recommends, i.e. brands/model number? Again, many thanks from a new subscriber.
Thank you. Hopefully Dr. Blue will see this question here and chime in.
- Martin
I feel i should clarify that CO2 (carbon dioxide) is still produced when lean-of-peak in large quantities. CO (carbon monoxide) is the gas that is essentially no longer produced once lean-of-peak. Perhaps i am mis-hearing the doctor at around 16:00, but i think he claims CO2 is what is no longer produced.
wonder what is his opinion on the new lightspeed headset co2 det.
Dr. Blue should develop and sell a small pulse oximeter that also detects carboxyhemoglobin. These are actually called CO-Oximeters. These devices exist (usually in hospitals and research labs), but are bulky and very expensive compared with pulse oximeters.
Great information. Do you have a link to his co det?
Sorry, I don't have a link.
- Martin
Awesomeness! Howdy Guy's!
Thanks, Arthur!
- Martin
Check out the long term effects of multiple hypoxia events on your brain, things like neural plasticity, and you’ll likely use O2 more often.
Beautifully done, Brent.
Other factors being equal, wouldn't someone living at altitude likely be better conditioned for flight at altitude?
Yes, that is correct. And D. Blue talks about that when he suggests pulse oximeter readings where oxygen is recommended/mandated (5%/10% below the home airport readings, respectively). Someone living at altitude will have a lower reading at their home airport, and that's OK because their are conditioned for that environment.
- Martin
I am wondering if there has been study on the effects of different proportions of oxygen in the cabin atmosphere for human physiology. For example, normal atmosphere has 21% oxygen. what effect will it have on human when you have 50% oxygen but at the pressure of 25,000 feet (5.5 psi)?
Considering the high altitude WWII bombers were unpressurized, I'd imagine some studies were done and any affects were not a primary concern at the time and circumstances. (That doesn't mean it is safe though. Concessions were made for many things then.) There probably were studies done for spaceflight also. For 25k ft though, that's not much higher than Everest. At really high altitudes, vapor pressure becomes a danger, but I don't know what altitude that would be.
Just need to calculate the PO2. But all those studies are in the literature too.
For your example altitude and gas:
PO2 sea level dry gas is 760mmHg x 0.21= 159mmHg
25k ft, PATM is 280mmHg x 0.5 = 140mmHg
Thus, without supplemental O2, dry gas PO2 at 25k ft is less than 60mmHg. Will not support useful consciousness, at least not to fly.
5:20 I don't get no respect. 🙂
