He talks about lungs with such passion, its breathtaking

[jopo]

This guy's presentation style is a breath of fresh air.

[casanford]

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.

[Vixenschuuring]

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

[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.

I love listening to people educate us with passion and no judgement to the questions.

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

[deweesegilyard]

Dr. Kalhan is amazing. I wish that I had him as one of my medical school professors back in the day. Thank you.

[ashm]

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.

"so if you're allergic to cats, get rid of your cat" WHOA WHOA WHOA

[BernardoWLopes]

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.

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.)

Please have Dr. Kalhan back soon, I am obsessed with pulmunology and he explains these things better than anyone I've seen.

[WellHelloBlue]

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

[idkvwad]

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!

[imbok]

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

[handkeez]

Please, give us a part 2 for this Doctor. EPIC presentation!🙌🏿

[Estefunny]

The way he said "Get rid of your cats" made me laugh out really loud

[mahuk.]

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!

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!:)
