"so if you're allergic to cats, get rid of your cat" WHOA WHOA WHOA
Me-allergic to cats but has 5 of them
@@springdeerling7866u don't say 😅
@@Ajay-kz9ns lol, I'm still allergic to cats but I just eventually get used to the ones I live with. Whenever I've rescued one of the streets though it was like 2 weeks of itchy eyes and runny noses
That's just crazy talk ...get rid of your cat is nuts.
ah yes, a man of culture 🎩
WIRED really have people in these vids who are passionate about their job and who can explain things really well. We need teachers to be like this
As an ICU nurse, if all the docs I worked with had this guy's bedside manner, everybody would be dying to get a bed.
Badum tissss 🥁
Come on, man.
I see what you did there😏

I love listening to people educate us with passion and no judgement to the questions.
I will try to passionalty educate you about anything you want ;).
@@MWisknight schurr up man

@@emilyjane9901 wow , thats sad
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.
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.
Nurses and doctors get so annoyed with me when I don’t understand the jargon 😭
he’s really the definition of “explain it to a 6th grader”
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.
Youre a fictional thing?
I feel like he would be great as a college professor. I like that he not only explains everything thoroughly in layman terms, but he also gives examples and visual representations of what he's explaining. It's engaging and gives me a better understandibg of the topic he's discussing.
College professors are fictional.
My lungs collapsed in april. Scariest thing in my life. I made a real good recovery. This really gave me some good information I needed
Glad you're alive😮
The doctor that treated you was probably a better source of info than a guy on a wired video on youtube
@@Splizacular that might be true, but that doesn't mean they had the time or the confidence to ask whatever questions they had with their doctor.
@@Splizacular The guy in the video is a pulmonologist. ALL HE DOES is study and treat the lungs all day long. How in the world could a general clinician like an ER doctor be a better source of info than a specialized doctor? 😑
Can I ask, what's it feel like, having your lungs collapse?
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.)
thats extremely cool
Lucky Big Tobacco did not discredit him and ruin his life like they did with scientists proving connections like this... very cool story, though. Did you ever smoke?
that’s AWESOME
Probably faced a lot of push back on his medical opinions at the time
How old a you lol
Ik everybody watching this rn is manually breathing💀
Dammit
you b1tc.h i wasnt and now i am bcs of ur comment
YES ITS TRUE WHEN WILL I STOP 😭😭
I’ve been vaping for about 3 years now and I’m so glad I watched this video as I’m in the process of quitting right now. This video really brought some clarity as to how much damage I’m actually causing my lungs to endure, thanks Dr. Kalhan!:)
There’s a lot of generalizations about vaping that really need some clarity in this video.
@@stealthhazard4846Yeah, EVALI has really only ever been identified in people using sketchy THC (weed) because of vitamin E acetate. If you don’t smoke, starting a vape is not a great idea, especially among young people. However, the National Health Service (the UK’s national health insurance) will pay for a vape if you quit smoking.
Congrats on trying to quit! I wish you luck on your journey. I know it’s not easy but your loved ones (and you, eventually) will be so glad! ❤
its a good idea to quit but this doctor is misleading people about EVALI and vaping...
me too i’ve been doing it for about year and a half so heres to us quitting for good😌😌
A doctor once told me that the ONLY thing you should take into your lungs is air. No smoke, dust, no nothing.
better not live un western US then
You don’t have to be a doctor to know this…
good luck finding clean air without dust and smoke 🤣🤣🤣
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.
@@malter87 Yeah, walking in the street among cars.
Dr. Kalhan is amazing. I wish that I had him as one of my medical school professors back in the day. Thank you.
u took the hardest one to pronounce kalhan not judging
@@tiberagamer6165 If you can pronounce fibromyalgia, I expect you to be able to pronounce Kalhan perfectly fine.
Doctors are fictional. Amazing in place of fictional?
You are so good at explaining things. I’m almost done with my masters of biomedical sciences and I WISH I could have had at least one professor who made as much sense as you
Done with fiction that includes masters?
I am a pulmonolgy resident and the realest habit of a pulmonologist is that they will make you listen to lung sounds through a computer haha and I was done when the balloon was out for description😅
The way he said "Get rid of your cats" made me laugh out really loud
😿poor kitties.
I’d rather get rid of my lungs lol
@@2kn111 😻🐈 Awww, so sweet!
tell me you're not a cat owner without telling me you're not a cat owner lmao
It made me laugh because I could FEEL the cat people typing lmao
Anyone else start taking deep breathes and become hyper aware of the act of their own breathing, while watching this?
Me. Hahahaha. I suddenly thank the Lord for giving me healthy lungs ❤
Yea, at 11:39.
Looking for this comment!
glad i saw your comment made me laugh
Fr I’ve been vaping 8 hrs straight everyday felt my lung collapsed for a bit lol
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❤
Even listening to this man felt good. He explains so clearly to those of us who have no medical knowledge, and I loved that section about bad lungs when he presented the sounds associated to a bad lung. Awesome!
Humans that dont know specific fiction?
Please have Dr. Kalhan back soon, I am obsessed with pulmunology and he explains these things better than anyone I've seen.
Please, give us a part 2 for this Doctor. EPIC presentation!🙌🏿
Idk if the Epic was intentional adj here but i actually laughed, Brilliant
@@getmeouttahere98 😅
I am now breathing manually
Let me tell y’all something, I really wish I had him as my wife’s doctor last month. She had to get hospitalized because her oxygen levels were at 85 and would not get any higher. She was on 10 liters of oxygen and it took her three days to get her oxygen levels to at least 90-91. She is asthmatic but we have NO IDEA what triggered her asthma attack. It’s been a month and she’s still not to where she was before she ended up hospitalized. He’s so informative and kind I wish he had been there to calm our anxiety down.
🫂🫂🌈
“How to train my lungs to not asthma” as a fellow asthmatic,i feel that
im surprised he didnt include Immunotherapy.
desensitising, while very expensive, is pretty effective.
Here in Australia it's like $10k for a full treatment, lasting a few years. in the USA it could be like 10 times that.
"If you're allergic to your cat, get rid of your cat."
I'd like a second opinion please.
Second opinion: go see an allergist and see if you're a good candidate for allergy shots. I've been getting them for two years, it's been life changing.
Buy a quality air purifier
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!
The way he explain everything so easily is amazing . Please, give us a part 2 for this Doctor. EPIC presentation!.
Doctors are fictional. You want some of my slaves dress/marketed with fiction while theyre abused, tortured and killed?
The way he explain everything so easily is amazing 👍
I have never seen anyone so excited about talking about lungs! This physician is awesome.
As someone who is currently going through tuberculosis treatment, coming across this video was really helpful to understand lungs better.
Tuberculosis is fictional. Did someone tell you it isnt?
Arthur morgan is that you
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.
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.
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.
This reinforces my choice to quit smoking! Almost 10 years
Proud of you 🎉
His energy is contagious, his passion is infectious.
man, i love this guy. lol really informative without being at all condescending. so friendly and genuine-seeming.
honestly a huge thank you to Dr. Ravi for his excellent delivery because I’ve learned more in 15m than I have in any doc appt using every scare tactic under the Sun to shame me out of smoking. Thank you for this breakdown. 🙏
Doctors are fictional. You thank for my human slaves?
I have a lung problem where I have no diaphragm on my righ side, it only gives me 70% of my lung capacity, I just got out of covid and am presently in a severe last longing cough. This was really informative. As usual a good host.
JW how did they discover such an issue? I ask cause my lung capacity was like at 40% normal not too long ago... like did they do any internal imaging? I hope you get better soon, I had Covid in the end of 2020, and it was tough- I nearly died and it took months to recover. It's been a couple years and I feel a lot better thou. Wishing you a recovery, too.
You have lung fiction?
@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.
They need create a table with correct data and oximeter data combined with skin color and calculate corrections for skin color.
I wasn't sure at first whether I was going to stick around to learn about lungs of all things, but Ravi is a really captivating speaker! Part 2...?
I finally understood why all breathing exercises comprise of long , bigger exhalation than inhalation! To Build up and keep up that lung elasticity and check / ensure that the lungs are healthy
This guy is super likeable. I hope he is in education; i bet students love his courses. Thanks!
I appreciate this doctor clearly, calmly,explaining stuff without fake hype or attention seeking nonsense.
What gives me pause is the peoples inability to google COPD, read its description, and understand it.
I rarely cant watch this kind if informative video for more than 5 min. I cant stop myself watching this video. So precisely he explained to the point.
Such a trustworthy and straightforward doctor
This was amazing. I could listen to this doctor talk all day and would never get bored. So charismatic.
This guy is awesome - I love the way he reads everyone's questions!! I love all the passionate nerdy geniuses in the world
I actually found this one really intriguing. He explained everything so well. The questions were also really good too! Hope To see more people like him.
“Get rid of your cat.” 😂 He woke up and chose violence. But the question is, if you have cat allergies, why do you have a cat?!!!
I have cat allergies and have a cat. There are ways to go about it.
@@Stephanie_Vincent Don't get rid of your kitty 😿
Get scuba gear and pet 'em 😸
I have 2 dogs I’m allergic to 😅. Sometimes you may love animals even when your immune system doesn’t.
We can't always choose who we love.
People may not know they're allergic to cats until they get one.
And sometimes, allergic can just develop. People who weren't allergic before become allergic.
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.
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.
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.
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.
They maybe thought humid air, like actual mist?
Very interesting and very well explained and broken down. Great Doctor!
Dr Ravi Kalhan is a gem ❤❤❤ please bring him more often ❤❤❤
It was interesting to hear him mention that young women often get lung cancer despite never smoking. I'm 23 and I had a bacterial infection in my lungs last year. I'm recovering well, but there seems to be no explanation for how I got it!
It’s community acquired
Do you use dry shampoo?
I thought I read somewhere that birth control increases risk, but I could be mis-remembering
Chemtrails
Cancer doesn't care if you've ever smoked or not. They like to leave that part out.
I do wish people would differentiate between OG vaping, using a vaporizer, vs. vaping cartridges/ juice.
The differences are important.
What are the differences 👀
Vitamine E acetate
Just stop vaping nibbas
@@dorime5018 *gg 😂
The differences? None, another form of smoking. Both cause health issues and potentially death......I know
He so expressive, and the way he speaks make me laugh, but he definitely knows how to break things down for people, and uses very good analogies
Just wow. What a phenomenal educator. Must be a great clinician as well. Respect!
people are not supposed to be vaporizing vitamin e acetate though, which is the only chemical positively correlated with vape induced lung injury. it was put into black market THC vaporizer cartridges because it visually looks like THC oil, but otherwise provides no useful benefit to the product. vitamin e acetate disrupts the lung surfactants and causes the injury, but regular vaping has never been shown to do that.
Indeed. Vit E acetate will not mix with a nicotine (PG/VG) liquid. It was ONLY ever used to cut THC oils. EVALI had nothing to do with 'ecigs' or nicotine vapes whatsoever
I wish I could have an appointment with him. Since having Covid in December my lungs still haven't gotten back to normal.
This is one of those rare videos I could watch without getting distracted for a second. WTG, Dr. Kalhan.
The way he explained COPD using the example of a balloon and a plastic bag.... Brilliant!
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.
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.
Yes, I believe non Hodgkins lymphoma is caused by pesticides.
Histoplasmosis too
@@cbpd89There are cheaper mitigation methods than hiring overpriced specialists selling dedicated machinery . One common technique is to ventilate the basement to the outside so the Radon blows away instead of seeping into the living spaces and staying around all day .
I live in Wisconsin, now I’m worried. 😂
Dr. Ravi's analogy game is on point. Thanks for the educating.
The way he explains things is amazing
I could honestly watch this man talk for hours and not get bored!!!
Love it. Please do one of these for every organ in the body.
This guy is fantastic! He needs another video for sure
This might have been one of my favorite Supports. Lots of information that is extremely important to know.
This guys enthusiasm for peoples deadly/harmful health symptoms made my night man.
So well explained. Thank you! Very informational without being boring.
This video got me manually breathing. 😂
I enjoyed watching him. Please have part 2 soon.
Amazing episode! Respect! Please bring him back for more!
This was surprisingly very enjoyable, and very informative.
Excellent presentation. Really enjoyed the information provided.
wow, I just learned more in 15 minutes than I did in 4 years of highschool. I could listen to him talk about lungs all day 😂
I can breathe easy knowing this doctor has answered so many questions about our lungs.
Thank you doctor, great energy answering every question!
The thing I learned with all these videos is the amount of people on Twitter who apparently can't ask a question with a proper sentence and grammar, or without being rude.
That was so interesting and he explained it in such an easy way to understand. Thank you!
My mom had pulmonary fibrosis and the sound of her lungs was indeed coarse crackle. Also similarly sounds like detaching Velcro. I appreciate this video.
Your first answer begs the question of what a lung without that unlucky vaping-associated lung injury looks like? Any chance you could do a follow-up?
Was wondering the same thing “hits vape”
Didn't he already show what an x-ray of normal lung looks like?
Rewatch the video, he literally showed an xray of non-smoker lungs... You high?
@@just_some_bigfoot_hacking_you he’s saying the question was “what does a capers lung look like” so they probably wanted to know if there is a baseline change in a capers lung when they aren’t sick
Hehehehehe. Rewatch stoney
His knowledge is breathtakingly good
Jesus Christ, I'm mid30 and this dude is talking to me like I'm a stupid 7yo!! Which is exactly the right thing to do to make me understand everything. Thanks Dr. Kalhan. 🤝
This is my fave wired video so far!!! Great explainations
Absolutely fascinating. Love all these lil dives into the science of us.
SO good at explaining things!!! Shout out Dr. Kalhan!
0:48 really cool how this comes down to entropy
I can tell you have passion for what you do. Thanks for that.
Very aware of my lungs right now
Probably one of my favorite wired support ( even though it was pretty specific)
Loved this a lot
Re: the section on ai helping with cancer
My mom had copd and had a couple tiny spots in her x-rays that doctors wrote off as scars due to her COPD
About a month before she died we were back in the ER for her breathing & the ER doc said they noticed a slight change in one of the scars. One biopsy later and it was confirmed cancer.
She had the tumors for YEARS with no change in them, and they were so small that further tests showed the biopsy had fully removed one small tumor.
Because she was 77 and very much in the end stage of COPD the oncologist told us "well, bad news is it is cancer but we can not treat it because of your health. The good news is it's so slow is growing it won't kill you"
That was the beginning of December. She was gone the 6th of January.
I am sorry for your loss and thank you for spreading awareness around the disease!
This is an awesome video. I don’t smoke or have lung issues, but a lot of these issues are affecting people I know.
super helpful! the diaphragm stuff was cool particularly bc i'd always assumed my lung capacity was good bc i played french horn as a kid, which you need a lot of air to do. then when i started wearing a binder as a teenager, my lung capacity went down again. i'd thought that it would've been the rib muscles or the lungs themselves that dictated this, but it being the diaphragm makes more sense! super cool :D
As a respiratory therapist, this Dr is a breath of fresh air.
..Ok I’ll see myself out lol
It’s entirely too bad that the comment at the top of the pile is someone else making this joke 11 days before you.
So you're a respiratory therapist and an optician?
Thanks! I love the way he answered the questions.
The way he explain stuff is really mesmerising.. i really like him, such a good explanation.
as a medical student this was fun to watch :) great video
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.
And you will have a good pulse oximetry reading with carbon monoxide poisoning 😱
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 .
Chemistry. Different number of bonds and co2 has a stronger chemical bond so is less reactive hence it being used to extinguish fires.
I love these sessions so much
Something about his presentation is so irresistible, I can listen to him for hours.
