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.
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!
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 👍
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
This dude is hands down the best channel I have seen on here for teaching biological/physiological/anatomical concepts Eddie woo is also on a similar level for maths
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! ;)
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!
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 🎃
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??
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?
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...
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...?!
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.

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

thanks dr I got more GOD to bless to you .....medical student from somali,mogadishu
Man that was awesome, I was learning about SEALAB and ended up here. Thank you for the lessons 🙂
If you explain the science behind, it stays with you longer. Thank you
Thank you for the video, it helped clarify a lot. I especially loved the soda bottle analogy.
You are a really great teacher!! I couldn’t grasp some really important concepts until I watched this lecture. Keep up the INCREDIBLE work !!!😊
This dude is hands down the best channel I have seen on here for teaching biological/physiological/anatomical concepts
Eddie woo is also on a similar level for maths
WOW!! THANK YOU FOR SIMPLIFYING IT FOR US.
AMAZING!! your way of teaching physiology is superb... thank u so much...
What a lecture
Thanks for finding a solution to my confusion
U should b awarded noble prize for this session..wonderful.
Im a beginner free diver. Great lesson!
Such a good explanation and super helpful!
THANK YOU SO MUCH, IT HELPS MY UNDERSTANDING A LOT !!
Super helpful, exactly what I needed. Thank you very much 😁
Execellent explanation, very few people can teach like this
ur lectures r awesome making it much more easier to understand. can u plz share videos on aviation, space and sports physiology
I only understood this concept from your vid 😊 thank you so much!
U nailed it !! Explained vry clearly and it is vryyyyyy easy to understand😊
Thnk u alot ..

this was really good
Amazing explanation!
Woah just WOAAHHH
U nailed it in 9 mins bro
Thank you very much
Thank you for this video. God bless you. 🙏
Great one sir… more knowledge for my scubadiving
So neat and so precise.. Great presentation :)
Thank you so much for simplifying this
An excellent explanation.. Thank you!!
Great video bro! Helped me a lot in physio
great comprehensive presentation thanks
it was very simplified thanks a lot Doc
This was a perfect breakdown 🙏🙏🙏🙏👍👍👍
I wish I was still in year 1 to make more use of this resource 💖
Best explanation ever!
I loved this .Thank you
شرح مثير شكرا صديقي ❤❤
This was awesome!

Thank you for explaining ❤
Dude... that was very helpful. thank you👏👏👏
Very useful information many thanks
Super teacher! Shukran jazelan
You are amazing dr
Thanks alot... Very helpful
Wow, thanks much for the video
Great video - request, would it be possible to explain the same but include mix gases as well please.
Great I learned so much
Thank you so much!!
Thanks a lot...❤️
Brilliant!
U nailed it💖
Thank you ❤️
Absolute legend
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.
Thank you, can I know the references you used and where do I get references on this particular subject.
helped me a lot thanks !
Thank you so much 😊
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?
God bless you
THANKS A LOT !! CAN YOU PLEASE MAKE A VIDEO ON FLOW VOLUME LOOPS ,
BEST, RASHMI
Thanks for this :)
Great work sir🥰 I'm from Pakistan
thanks!
Thankyou... 🙏🙏🙏
Perfect
Love you a lot ❤️
you are the besttttt
Thank you! i dont need to open my confusing textbook now😁😊
It's better explanation compared to our physiology text book...
Please make in this context a video about co2 retention in context of increased gas density 😃
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??
Amazing ☆ミ
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?
Please explain what if you are diving at 145 meters without oxygen
Started well, but ... I don't breathe water while diving. I don't breathe the atmospheric air there either.
5．分かりやすい
If you’re diving you don’t take in atmospheric air so where does the high pressure nitrogen come from
👏👏
❤❤❤❤❤❤
CAN THAT CAUSE DEATH WITH A PERSON SUFFERING FROM HIGH BLOOD PRESSURE
When you say "nitrogen sickness" @8:00 don't you mean "Gas Narcosis" which can be caused by both Nitrogen and Oxygen?
aamaazzzzinnngggggggggg
takoe bre objasnio
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...
I’m struggling with deep sea physiology currently
And this is the exact question I asked
Please did u find an answer 🥹🥹🥹
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...?!
you are a epic
Oh my Caisson's Disease? Why it is bend???
Amazing illustration 👏
Great explanation for idiots like me. Also you look like a more buff version of richard hammond
what gas law is this associated with?
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.
@@m-linko Thank you!
4 atmospheres at 30 meters? I count 3. What's wrong?
Good ass vid
