Silent Bubbles of the DEEP: Decompression Sickness

[@ShibinAbrahamtunnelview]

Absolutely Brilliant Video ❤

[@DodgyDaveGTX]

2:16 don't think I didn't notice that low-key mic swap 😉

[@ABCDiver]

The video is very informative in addressing DCS in general. I just have a small note: gas molecules themselves do not compress, it's the space between them that gets reduced.

[@gee4526]

Great video Paul, I've never had the decompression theory explained so thoroughly. I wish it had been when I learned. you made it simple and really easy to understand. Thanks for your time and your fantastic outputs,

[@WaterlineShorts]

hey Gee. it's been a while. thanks for saying so. I must admit I really enjoy trying to simplify these topics. thanks for watching and commenting.

[@scottcalder2384]

Brilliant video, I'm currently studying for the Open Water Dive cert and this explanation is well understood. Informative, clear and interesting - thank you.

[@WaterlineShorts]

Brilliant, thanks for saying so. I hope you enjoy your open water. It’s an entry into an entirely new world. Happy diving

[@yusufnasrul6613]

This video deserved get more view and like

[@WaterlineShorts]

Thanks. Im sure over time it will. Happy Diving.

[@swichv64]

Easily the best video about DCS I've ever seen. Thank you!

[@WaterlineShorts]

Thanks for watching. Im really glad you found it useful.

[@dvbville6171]

Really!!! You are the best english language speaker ive known.. your diction tone and accent are clear and understandable especially for foreigners hearing technical words. I followed your page because of how you connect to your listener...

[@WaterlineShorts]

Thanks. That's very kind of you to say.

[@BangCiihuy]

The best video about DCS.

[@WaterlineShorts]

Thanks, I appreciate you saying so.

[@BangCiihuy]

@@WaterlineShorts yes because I was trying to search this kind of videos, several times I found some videos I think it was English but in fact they were Hindi or some kind of English with Hindi accent and those made me upset.

Helium does not eliminate the risk of narcosis but it does significantly reduce the effect . There are measures of narcotic effects of different inert gases which helps to decide which gases to be used

[@amookalyptica]

Fantastic video! Golden work about DCS!!! Big kudos for the depth of the content along with a great explanation. I'm taking my rescue diver training now, e-learning completed and tomorrow is the first two dives as part of the training. Perfect complementary info :)

[@WaterlineShorts]

Ha. Thanks. To be honest it's nerve-racking to put out a video on a technical topic that needs to be such a long video to cover everything off. So it's great to get positive feedback. Thanks for watching. Rescue is an incredible course. The in water segments are one of the most useful and enjoyable of any course. Enjoy your rescue dives.

[@jayeshsharma1176]

Wonderful 💯👏🏻 Highly Appreciable.

[@brucew9533]

So lets say im clearing weeds and such in 10 feet of water around a dock. What will happen if im on the bottom for a while.

[@michaelamacdonald4226]

How do you read a book underwater is there a diver book store that sells waterproof books? 19:35

[@rhondamyers8795]

I wondered the same thing.

[@franksmith6741]

How much Nitrogen compressed air for 5,321

[@leanneclarke9920]

My brother who had been saturation diving for 30 years, went on a dive to 75m last January, ran out of air, had to ascend quickly, and died from the bends, just terrible

[@WaterlineShorts]

Oh geez that's awful. I'm so sorry to hear that. My condolences

[@prashantraj4828]

BREATHING OXYGEN WILL NOT BECOME TOXIC UNLESS THE PARTIAL PRESSURE GOES ABOVE 2 BARS. IDEALLY FOR AIR WE CAN DIVE UPTO 90 METERS(AS PER CALCULATION) BUT DUE TO NARCOSIS AND SOME SET LIMITATIONS WE DONT.

[@robertwilson9698]

You misspoke when you said a Nitrogen molecule at 1atm of water depth is squeezed to half it's original size at the surface. That's incorrect, when a gas is compressed the molecules see very little change, and it's the space between then that is reduced to allow more molecules to be packed into a smaller volume.

[@WaterlineShorts]

Yes good point. Someone corrected me on another video. I do like the details.

[@blastyfs2]

would using a tank of pure oxygen be viable? I know that oxygen is a corrosive gas and sometimes it can cause bleeding in the lungs if used for too long

[@WaterlineShorts]

No you can’t. You would get oxygen toxicity.

[@blastyfs2]

@@WaterlineShorts looked it up, didn't think that pressure would have any effect on it I just knew that NASA had used pure oxygen in the past to pressurize the apollo crew capsule until there was that spark that ignited the oxygen and killed the 3 astronauts in it before they could get the door open (due to the door only being able to open into the spacecraft instead of out)

[@WaterlineShorts]

I didn’t know they used pure oxygen. Pressure definitely has a big effect. Makes sense though for high altitude. Pressure as in diving deep concentrates the oxygen so you get too much. Conversely climbing a mountain the site gets thinner so a lower concentration of oxygen. Space flight would also have a lower concentration which is probably why they use it.

[@blastyfs2]

@@WaterlineShorts U2 spy plane pilots were also made to breathe pure oxygen for a full hour before flight at one point as well, not sure if they do it anymore

[@WaterlineShorts]

@@blastyfs2 interesting. Im sure Pilots have Oxygen with them in case of emergency but I would imagine that cockpit's are pressurised so they only need it in case of depressurisation. I think in the old days the airplane cockpits would not have been pressurised.
