what happens to the lungs of a freediver during a deep dive, boyle´s law in action

- experiment with a liquid meter, open and turned upside down. it plunged to -55 m with 1 liter of air inside. the water pressure push up the air, compresing it to 154 ml at 55 m depth. the air expands while climb back up to 1 liter.
glad you all liked and understood this expermient, i would liked to bring it to -70 m at least, but i didn´t want to risk my gopro (limited to -60 m) Saludos desde Canarias, keep trainning
What's more impressive is the way you casually did 55m dive
Dude went to 55m, then casually says he'd go to 70 m but his gopro can only handle 60m. lel
This is such a good video to demonstrate how this works! ITs crazy how quickly the air compresses in the first 10m
Wow. If I ever went diving (free or scuba) I'd probably have a panic attack and die lol
I loved how u have the vto voluntarily tube opening or btv maneuver wow. Beautiful. Liked and subscribed 😍
Wow thx for sharing pretty crazy stuff had no idea about how that worked!
To help out anyone with fears Not many of us normal humans are freediving to 55m or 180 feet deep . My personal max is 16 meters I have never waited to go any deeper.
Am I the only one who feels a heavy weight on their chest when he reached the bottom kinda like we’re there holding our breath with him 😬😬😬😬😰
good video, very like the way equalize
One can hear the sound change with the increasing pressure.
that makes it easy to understand the relation of pressure and volume...
I think the lungs of the freediver collapse to a certain level, depending on the biomechanical resistance of his/her torax (skin, rib cage tension, muscle tension, blood pressure, etc, that offers the diver as natural barrier) and his own ability to resist the water pressure at that depth. The interphase water/air within the inverted canister is the smallest kind of resistance we can imagine in diving. If we added a wall (e.g. a flexible, impermeable membrane like that of a ballon as an interphase), depending on its hardeness and flexibility, the final airvolume at the same depth would be larger than in this experiment. The most extreme case would be, for example, a thick metal sphere full with 1 L of air at atmospheric pressure and hermetically closed. In this case, the air pressure/volume at 60 m would obviously still be 1 atm/1L. My point is, the lungs of the freediver are of intermediate "resistance" between the example shown in the video and the case of the metal sphere. Therefore, the air volume in the lungs of the freediver is not reduced to the same extent as the air in the canister. Although I do not know much about freediving technique, I am pretty sure they must try to keep the shape of their torax to avoid some kind of extreme lung squeeze.
Nice Frenzel technique!
If I smile hard, the tubes open and my ears equalize without blowing
is there a lungover expansion sensor to detect any problems???
Thankyou 4 making
And that's why Our Lord created bloodshifting: you can pressure gas, but you cannot pressure liquid, so our body (in order to protect them) shift blood into the lungs to keep them from squeezing.
You should flip the "bucked" when you are that deep, would be cool I presume.
Going by the title of your video, it doesn't really show what happens to you lungs but what happens to the air in your lungs.
