My father was a doctor, getting his degree in the 1940s. His mentor was training in the early 1900s. He told my dad the hospital had a patient with lung cancer and all the doctors came to the autopsy, because they had never seen lung cancer before. After WWI, when every Care Package to a US soldier went with a pack of cigarette's courtesy the tobacco companies, lung cancer became depressingly common. He was one of the first doctors to make the link between smoking and lung cancer, and he sold my dad on it. (He also helped develop Resusci-Annie.)

I'm a Med student and and previously licensed Physical Therapy and I really aspire to be such a clear communicator as this man. It can get very hard to provide clear explanations that satisfy the person in front of us without either getting too deep into jargon and pathophysiology or just rummaging through the surface without being clear on anything. He explained all of these things extremely well and balanced for laypeople! Good man.

[@symbolsarenotreality4595]

Vapor is rounded water particles, smoke is microscopic jagged carbon particles that cause microabrasions. Vapor can carry tobacco or cannabis oil for example and if you vape too much this can clog the lungs up with more material than it can expel with its mucous lining. Smoking however clogs the lungs up much quicker and of course causes inflammation.

[@jaspizzazz]

Nurses and doctors get so annoyed with me when I don’t understand the jargon 😭

[@safm541]

[@aos-archive]

I do tech support I always remember that explaining with jargon and abbreviations to someone unsavvy is not effective. You may sound smarter, but your message isn't being successfully received. Always remember to use simplier words that they can jive with unless they are requesting for clarification. I don't need to tell people what our system is called where we make changes to someone's access. I just refer to it as the "system" when I need to identify it.

Cystic fibrosis also causes that horrible “crackle” sound! My best friend’s lungs made very loud crackle sounds. She died 4-5 months before quarantine in the US began, in November, before hospitals knew anything about COVID. All they knew is that she suddenly became much, much worse. Which is possible, but I always wondered if she was one of the first cases of COVID before the doctors knew what it was. I’ll be lost without her forever❤

Ive been a respiratory therapist for about a year now and i absolutely love how you compared emphysema lungs with the plastic bag. Very fitting and im surprised i never heard that example in RT school!

[@SpiritmanProductions]

His answer to the "mouth-to-mouth" question missed the key point: We only absorb about a quarter of the oxygen that's in the air we breathe, so when we breathe into another person, that air still has an oxygen saturation of about 16%, compared to the 21% in fresh air.

[@imbok]

A doctor once told me that the ONLY thing you should take into your lungs is air. No smoke, dust, no nothing.

[@bigweed]

[@DOC_951]

You don’t have to be a doctor to know this…

[@malter87]

good luck finding clean air without dust and smoke 🤣🤣🤣

[@ether4211]

They're correct. Sadly the WHO estimates that over 99% of the world lives in places with air quality in excess of safe limits. If people care about their health they should start taking a interest in the air around them and push for stronger standards. Indoor air quality is often worse then outside - so steps to improve it include getting rid of fragrance, making sure your kitchen is ventilated and encourage people to not smoking or vape around you or children. While it may seem 'boring' if you care about your health and those of others it's worth looking at ways to reduce your exposure.

Doctors are fictional. You want some of my slaves dress/marketed with fiction while theyre abused, tortured and killed?

[@maranorth]

@Dr Ravi - there was a study in Canada that suggests that accuracy of the pulse oximeter depends on your ethnicity. So - as you mentioned - the sensor is based on infared light, so those with dark skin actually got incorrect readings about blood oxygen levels. So, for those in the medical community, it is important to be aware of that study.

[@kirill9064]

They need create a table with correct data and oximeter data combined with skin color and calculate corrections for skin color.

[@LamanKnight]

Oh, now I get it! When I got COVID-19 for the first time, I was very sick for two weeks. Yet it wasn't until after the infection was gone, that I had to go to the hospital a couple times. On that second hospital visit, the nurses and doctor were suddenly nervous and rushing around, because the instruments said I had a dangerously low blood oxygen level. Lucky for me, they scanned and found that my lungs were mostly ok; it was just that I had almost no circulation in my hands. So... the hemoglobin in my hands' blood vessels was sluggish, moving less oxygen, more slowly than usual, making it look like my whole body was not getting enough oxygen; but my essential systems were still in reasonably good condition, for someone who'd endured what I just had. My body was just triaging its resources, meaning the medical instrument gave a misleading idea of how I was doing overall. And now I understand how that happened. It feels satisfying to understand this now. Thank you, Doctor.

[@Memento_Mori_Morals]

Covid is scary. I'm rather young but it nearly killed me, and this was a good year after my asthma was well-controlled. I would be dead if I hadn't decided to go to the ER for a nebulizer or something, and then them finding my BP dropping.

Back in the late 80s when I was a kid, a doctor told us that breathing wintery air would help when I got an asthma attack, if it was too soon to take another dose of my rescue inhaler. So my mom had me bundled up standing outside taking as deep of a breath as I could of the cold air. It felt like it helped. But, if its worse according to Dr. Kalhan, it maybe have just been a placebo effect then. And now that I have grown out of my asthma. I love breathing in cold air, it almost has a soothing effect.

[@TheGalacticGrizzly]

I have asthma and I love the cold air. I have way more trouble with hot and humid conditions. So I guess it depends on the person.

[@eleanastclare]

Our docs have always told us if our kids had breathing problems, open the window and bundle them up! It is the moisture in the cold air that helps. Same reason a humidifier works to ease breathing. I may be wrong, but I believe it depends on the cause of the asthma or illness as to whether it works or not.

[@stephanieaya3992]

If you got allergy-induced asthma (like I did as a kid in the 80’s), breathing in cold air outside where most of your allegens are dead/non-existent will make you feel better. If it’s below freezing and there’s very little air pollution, all the usual suspects to trigger an attack are gone.

There's another big source of lung cancer in the Midwest...a portion of it is called 'the cancer belt' because of it. Some of it is radon in basements, but also because of all the farming people end up inhaling particulates like dust and plant matter, as well as herbicides and pesticides. My grandfather died of lung cancer and never smoked a day in his life. It was the farming.

[@cbpd89]

We've got radon in my area as well. A radon mitigation system is literally thousands of dollars to install, so I guess folks will just go on getting cancer because we can't afford not to.

[@leviathan68w78]

Couple of quick things. As he mentions, the reason oxygen goes in to the blood and carbon dioxide goes out of the blood is diffusion because of the difference in concentration. The gasses want to equalize. Secondly, the hemoglobin has an affinity for carbon monoxide as well as oxygen.

[@MajorAddiction]

And you will have a good pulse oximetry reading with carbon monoxide poisoning 😱

[@kitkatkatsuki8629]

yep, as well as it having a 250 times higher affinity for CO than oxygen

Lungs function a bit like gills on fish, but optimized for exchanging oxygen with oxygen-rich air instead of oxygen-rich water .

"Vaping", applied to cannabis, is just as likely to refer to vaping pure flower, not juice cartridges. Vape kits for bud like the Pax 3 and Volcano are very popular. I'd love to see an actual answer to the "vape vs combust" question, since I use a lot of flower personally for epilepsy, but everywhere I look I see the same outdated info that only addresses vape carts, as if vape pens & rigs that use raw flower don't exist.

Hello, fellow epileptic here. Try switching to a sublingual oral spray that goes under the tongue so you risk no lung damage and receive the medication better.

The UK has really clear research on vaping and it's undeniably a significant harm reduction tool for smoking cigarettes. I'm surprised he didn't provide that context or directly answer the question. Equivocation on smoking vs vaping isn't helpful, or accurate. One is a combustion product which is automatically worse (same goes for smoking marijuana vs vaping it.) He also kinda wiffed that question because vaping marijuana doesn't just mean hash oil, you can get dry flower vaporizers, which are also better for you because you're just heating it up enough to vaporize the THC, not burning it and inhaling a combustion product.

[@MousechrisTFM]

Love it! The explanation for Covid was great. Shame that there wasn't any discussion about the effects of air pollution on our lungs though. For heavily polluted countries like Pakistan, or coal countries like South Africa, or dense motor cities like Jakarta, what is the true cost of having to breathe in dirty air all the time? Recently there was a gas station/fuel depot explosion in Jakarta, what does breathing in the fumes do to you? How does this affect children and adults? Would you still recommend adults and children to get exercise under such conditions? Do air purifiers really help? Would love to have a follow up that addresses/discusses this somewhat

[@Alex-ro6tj]

As someone who has had asthma since childhood, you actually can kind of train your lungs to "not asthma." When having an attack, if you clear your mind and relax and sort of meditate, and don't think about the attack, the attack will go away on its own. This is similar to other things like pain endurance or holding your breath, where clearing your mind and acting like it's not there can trigger your body to believe it's not having an attack. It's almost like hypnotism.

9:49 my son is a micro prem baby, he was born at 24 weeks. i always wondered how that monitor that we put on his foot could read what his saturation levels was at but never asked about it. thanks for the explanation on that. because he was born so early his lungs hadn’t fully developed so he has breathing problems and is very prone to getting sick which ends up with a couple days- a couple weeks in hospital depending on how bad he gets, most of the time it’s just bronchitis, but he has had bronchitis, bronchiolitis and RSV which landed him in hospital for 3 and a half weeks. he’s a fighter and is 10 months old now slowly getting stronger.

[@Wollie1979]

3:30 I like when he actually says the letters WTF and not the whole sentence 😁

[@TheGooglySmoog]

He's one of the better experts on this series.

[@TheRealBigJake]

I think he's confused between vaping and tainted THC carts.

[@supshawty2348]

Anybody watching this, are you breathing more when while watching this lol

[@esdietsch]

could listen to him all day. he needs to be the surgeon general.

Top marks to Dr Kalhan. Clear, direct, accessible, stimulating, enlightening, educating. 👏👏👏👏👏👏👏👏

Has vaping associated lung injury ever been found in people who only use "normal" pg/vg/nic vapes? I've only found examples that turned out to have been weed oil vapes cut with Vitamin E acetate (which turns into acetic acid of vinegar when heated) Edit, at 6 minutes he also associates vaping with cannabis, so I'm not even sure he knows nicotine vapes are a thing.

[@kelvingunawan1099]

There hasn't.

[@maddiepasiewicz3197]

SO good at explaining things!!! Shout out Dr. Kalhan!

[@aresjupiter847]

i am amazed by the simplicity off the explanation of COPD with a *grocery bag*

[@Beth-l5c]

What an excellent teacher!

[@lanabeck6077]

I think that the higher rates of young women (non-smokers) who develop lung cancer may be due to aerosolized beauty products, such as hair spray, deodorant, and setting spray

[@vinnyc7613]

um, a little sexist are we? men dont use such products? does that mean being a hairstylist is condemmed to a life of chronic lung problems or even early death, any lawsuits by the beauty professionals on product manufacturers? assumptions arent scientific, they just creat rumors

[@Joshpmat1234]

​@@vinnyc7613 this comment ain't sexist at all chill

[@EvilForgemaster]

​@@vinnyc7613seriously, everytime I see a sensitive little s**t like you, I will always come to tell them to f*** off. So yeah, f*** off

[@lanabeck6077]

@@vinnyc7613 hi vinny. i mean that more women tend use these products, therefore this phenomenon would occur at a higher rate among them. it's a theory (and it was posited as such), which would need to be tested among men *and* women. hope this helps with your close read of my comment :)

[@lawyerpanda1856]

Good point😅

AI can identify gender based on retinal scans, so I think this doctor's prediction about AI being sensitive to things we can't see is already right on the money. Also, fun fact: the first aid for pneumothorax is to put something like a plastic bag over the hole and tape three of its four sides down. The plastic seals the hole when the person inhales, but the loose side still allows for the escape of gases and fluids.

Pulse oximeters emit BOTH Infrared and Red wavelengths of light. The differential between these two waves as they’ve been absorbed by blood before reaching the detector on the other side of the finger is what allows a saturated percent of oxygen to be calculated

[@mattysheehan9786]

It’s astounding that somewhere there’s a kid/adult out there who took the time to type a question about the basic definition of COPD, only to wait for a response days/weeks/months in the future, when all he had to do was type the exact same thing into google for an immediate answer to his question. The amount of effort taken to avoid the effort of reading and learning boggles the mind

[@pastasoo]

Wow a lot of this happened to me, I suffered an unexpected pneumothorax during an operation before that required resuscitation and put me in a coma for 3 days. I woke up and caught pneumonia while in the ICU and then because I was stuck in bed for almost an entire week, they made me use that inhaling toy thing although the nurses didn't explain why I had to do it, they just kept forcing me to do it

[@vaikunthramakrishnan]

Amazing episode! Respect! Please bring him back for more!

[@danieldomeier5657]

Everyone watching this video is breathing manually

i hate you
