Diving Physiology | Respiratory System

[@backlogbrood2451]

After having to watch many frustratingly confusing explanations, which almost never even attempt at explaining the science with examples (like you do), this explanation is, by far, the best. Thank you.

[@jmichael34]

Thank you for explaining so well what happens in nitrogen sickness. I watched five videos before this one and was still confused, but you helped me understand what is happening in the body's respiratory system through your clear and straightforward explanation. Well done!

[@dalalalotaibi2211]

I liked how you illustrate everything so quickly ! and your body language is awesome 🙏 god bless you ✨

[@darrenpattison7674]

I'm a Biology Student and I came here after watching '47 Meters Down' to better understand. This fits so well with what I'm learning about Gas Exchange and Transport. There was even a respiration reference too. Great video

[@yeeroy]

I’ve been using your videos to study as a pharmacist and what a pleasant surprise that you even covered this topic!! I’ve been binging cave diving disaster videos and wanted to understand the physiology behind the incidents 👍

[@saj1dsal33m]

If you explain the science behind, it stays with you longer. Thank you

[@johannesmuller6798]

greetings from germany. currently studying for my final paramedic exams but couldnt find any helpful videos so far... then you came along and saved the day! thank you so much for uploading but even more importantly explaining/ teaching with such passion and enthusiasm. thank you!!!!

[@ebruyldz4680]

Omg, for so many times I tried to understand decompression illness and no other video helped me more than yours to me to grasp the logic behind so easily. Thank you so much 😊🙌

[@sahalsayid9365]

thanks dr I got more GOD to bless to you .....medical student from somali,mogadishu

[@ghotboy9238]

Man that was awesome, I was learning about SEALAB and ended up here. Thank you for the lessons 🙂

[@whityreddydr1775]

U should b awarded noble prize for this session..wonderful.

[@zarzanator1991]

Im a beginner free diver. Great lesson!

[@ayeshashabbir6684]

You are a really great teacher!! I couldn’t grasp some really important concepts until I watched this lecture. Keep up the INCREDIBLE work !!!😊

[@subhranilmanna9715]

ur lectures r awesome making it much more easier to understand. can u plz share videos on aviation, space and sports physiology

[@MaliamAngel97]

WOW!! THANK YOU FOR SIMPLIFYING IT FOR US.

[@fatimatuzahra3740]

What a lecture Thanks for finding a solution to my confusion

[@ummarahsandhu4317]

this was really good

[@iyadmen9466]

it was very simplified thanks a lot Doc

[@Pieluszek78]

Hello Dr Mike Thanks for that and for others videos like henry's, dalton, boyle's laws and also respiratory and circulatory system and few others video. Im scuba diving instructor and ill have to teach those things to my future students. You explained that in easy clearly and really simple way! You are great! :) Both of you have good channel! ;)

[@kimtaekook9965]

Woah just WOAAHHH U nailed it in 9 mins bro Thank you very much

[@kathymania43]

Thank you for the video, it helped clarify a lot. I especially loved the soda bottle analogy.

[@user-zy7wf7tu4g]

Amazing! I realize I understood absolutely nothing before that video. The whole physics explained with no mumbojumbo. Should be transposed by all dive agencies - I’ll never be able to reproduce the whole argumentation, just watching with mental satisfaction 🎃

[@Hawk-courage]

Very useful information many thanks

[@farahkhan7718]

AMAZING!! your way of teaching physiology is superb... thank u so much...

[@avila8331]

Amazing explanation!

[@UPAKHOSALA]

Execellent explanation, very few people can teach like this

[@cathleenpatane6855]

great comprehensive presentation thanks

[@natashadeerwester-hall8971]

Such a good explanation and super helpful!

[@liridonsopaj7249]

Easy, simple, clear, GREAT! Congrats!

[@elensmartinez]

I think something might be wrong. But first: very good video!! Very well explained, congratulations. What you call "Nitrogen sickness" it's actually called narcosis, and it has been found that oxygen has basically the same narcotic effect as nitrogen at depth. I take this information from PADI enriched air nitrox diving instructor manual 2023 Again, good job! Looking forward to read your input on the topic. Thanks!

[@caribaez5711]

Thank you for this video. God bless you. 🙏

[@jagdishchandra8251]

Wow excellent explanation

[@imankhai8182]

THANK YOU SO MUCH, IT HELPS MY UNDERSTANDING A LOT !!

[@Adukestation]

Thank you so much for simplifying this

[@DrKAli-un5lt]

I wish I was still in year 1 to make more use of this resource 💖

[@planetaryorb]

I only understood this concept from your vid 😊 thank you so much!

[@IsmailSal98]

Super teacher! Shukran jazelan

[@al-zawahifmag]

شرح مثير شكرا صديقي ❤❤

[@PensieriProfondiScuba]

Great video about how the partial pressure of gases under pressure work but is not yet clear to me the CO2 effect on our body. There are articles that state that the CO2 is more narcotic than the Nitrogen itself because can dissolve easier in fat tissues, better than Nitrogen, being therefor the main cause of Narcosis. Could you elaborate the relation between CO2 and Narcosis while scuba diving? thanks

[@andrewgirling6137]

Great video - request, would it be possible to explain the same but include mix gases as well please.

[@ajaynangalia334]

An excellent explanation.. Thank you!!

[@MohammedsafeerSharief]

Thank you for explaining ❤

[@Ralf_4848]

This was a perfect breakdown 🙏🙏🙏🙏👍👍👍

[@اتابر]

You are amazing dr

[@lionsinescanor373]

Great video bro! Helped me a lot in physio

[@robbynatividad6857]

Great one sir… more knowledge for my scubadiving

[@arahmay4060]

Which do you think is more influenced by water pressure changes: the oxygen in a diver's lungs or the fluids in their blood and body tissue?

[@scholarshipworld1]

Great work sir🥰 I'm from Pakistan

[@najmeddinezaga2919]

Dude... that was very helpful. thank you👏👏👏

[@talhazafeer9471]

U nailed it💖

[@harankumar1]

So neat and so precise.. Great presentation :)

[@abdullaabouda5167]

Thank you very much, very good informative video.

[@sanasampyal7663]

U nailed it !! Explained vry clearly and it is vryyyyyy easy to understand😊 Thnk u alot ..

[@ambesaamber8068]

Super helpful, exactly what I needed. Thank you very much 😁

[@easy-peasy9906]

God bless you

[@manalal-sawwafia7279]

Best explanation ever!

[@thepixelgamer3d913]

Absolute legend

[@220819908472]

Please make in this context a video about co2 retention in context of increased gas density 😃

[@MsKorey45]

Great I learned so much

[@amjathmohamed3221]

It's better explanation compared to our physiology text book...

[@murukeshtimetvm4119]

Thank you ❤️

[@aakashchoudhary4377]

Wow, thanks much for the video

[@williamsweet7511]

you said each ATA decreases the volume of gas by 1/2 but it is really 1/2 of the volume that was left. So you never get to zero gas volume, or did I miss something??

[@neovision-u3q]

nice explanation

[@deepikaaggarwal5124]

Thank you so much 😊

[@charithdissanayaka5171]

Thanks a lot...❤️

[@smokonlytree]

This was awesome!

[@mrzalnotazy2203]

Brilliant!

[@karma_sama1402]

Thank you so much!!

[@tendaikelvinsaungweme5971]

I loved this .Thank you

[@MikeHunt-no2kt]

I understand we have known about these fluid dynamics before scuba became mainstream, but how many scuba pioneers were injured or died perfecting the science of deep diving?

[@asrashohani1771]

Thank you, can I know the references you used and where do I get references on this particular subject.

[@NOOBfromHELLyt]

helped me a lot thanks !

[@elmiraivazov2631]

Perfect

[@sheharyarshahid2017]

Thanks alot... Very helpful

you are the besttttt

[@ruksanakhan4989]

Thankyou... 🙏🙏🙏

[@ngirabedechal]

I would like to know about the effects of pressure on the the other parts of the body like organs and tissues that don't have any voids the heart ect.

[@wethenatureenthusiastssa1736]

Thank you! i dont need to open my confusing textbook now😁😊

[@cornflakes3851]

Love you a lot ❤️

[@rashmii.k1887]

THANKS A LOT !! CAN YOU PLEASE MAKE A VIDEO ON FLOW VOLUME LOOPS , BEST, RASHMI

[@UPAKHOSALA]

Please explain what if you are diving at 145 meters without oxygen

[@asmaabbas1110]

Amazing ☆ミ

[@eqisoftcom]

Started well, but ... I don't breathe water while diving. I don't breathe the atmospheric air there either.

[@fitticent7260]

If you’re diving you don’t take in atmospheric air so where does the high pressure nitrogen come from

[@cmr5180]

Thanks for this :)

[@WorldMaverik]

When you say "nitrogen sickness" @8:00 don't you mean "Gas Narcosis" which can be caused by both Nitrogen and Oxygen?

[@sheilagreasley-rush4423]

CAN THAT CAUSE DEATH WITH A PERSON SUFFERING FROM HIGH BLOOD PRESSURE

[@levongabrielian6430]

The analogy between 1l of gas (0n the left side scheme) and the gas inside lungs is not so relevant since the volume inside lungs is not changing (chest volume inside ribcage is the same) and water is not going into breathing space. The pressure on the whole external body however is changing. So...?!

[@なっち-e4z]

5．分かりやすい

[@brewedmeditation2886]

Oh my Caisson's Disease? Why it is bend???

[@professionalyoutubecomment7272]

4 atmospheres at 30 meters? I count 3. What's wrong?

[@hibaalgaali2831]

Thanks a lot for your amazing explanation, but you speek too fast. Will you Please slow down a little bit

[@Bullzmilk123]

what gas law is this associated with?

[@m-linko]

You can use Henry's law, C=P x solubility (concentration of dissolved gas = partial pressure x solubility), and an understanding of PV=nRT. As partial pressure increases with depth, the concentration of the dissolved gas increases (more nitrogen dissolved in blood). As divers come back up, pressure decreases and volume increases (by PV=nRT) which can lead to bubbles of nitrogen.

[@Bullzmilk123]

@@m-linko Thank you!

[@DA1TIEGO]

how is there an atmosphere below water? Isn't atmosphere the envelope of gases surrounding the earth? Also arent you breathing with an oxygen tank? im struggling to connect the dots...

[@Abbyslikkle_space]

I’m struggling with deep sea physiology currently And this is the exact question I asked Please did u find an answer 🥹🥹🥹
