It's NOT 42% oxygen at 10m. The correct explanation is that the partial pressure of oxygen at 10m is 0.42 bar. (The partial pressure is changing, not the percentages of gas)
Hi Amy Can you tell me how to calculate the amount of exposure to oxygen from multi-depth dives As the tables are based on the fixed depth according to the values of exposure And the second question does it appear in the Maris Smart Air computer? the % of exposure ? The third question: i know that nitrogen absorbs less than oxygen in diving usually. If that is the case, does oxygen have the same property, or is it that when it reaches the upper limit of 1.4, we can only go up to a higher levels and drop quickly? I hope the question is correct If you think it is appropriate to explain it in a video, I would be grateful As our trainer died, he made a technical dive at 65 meters, then after he finished the dive after 20 minutes and at a depth of 35 meters, he wanted to change to the Nitrox 37 cylinder, so he mistakenly replaced it to the cylinder with a concentration of 80, where according to the words of those who were with him, the oxygen was almost at His ascent reached 1.6. When the error occurred, the ratio shifted to 3.55. Can you explain what happened? Thank you for your wonderful communication.
I have a question. Why are regulators cable tied to the mouth piece? I’ve seen a few times them just fall off on divers under the water.....is there no other way they can be fitted safely?
The reason this is happening could be down to two things. 1. The cable tie has not been fitted properly, neither the mouth piece. 2. (And this is usually the issue) the mouthpiece used is NOT compatible with the 2nd stage of that regulator. Contrary to popular belief, you are not meant to put any old mouthpiece on a regulator - unless specified by the manufacturer that it is infact compatible. Alot of dive centres will just use any old mouth piece, for convenience and cost... and sometimes this can result in them dislodging from the 2nd stage. Unfortunately, the rubber material of the mouthpiece means it gets damaged easily and will need to be changed quite often so there isn't really another suitable way of attaching it. As along as you use a compatible mouthpiece and it is secured correctly, then it should never fall off. Good question! 👍👍👍
This is the video that finally explained this in plain English. Thank you!!!!!
Here's a huge thanks from an 11th grade chemistry student. I couldn't find a simpler explanation of this and thank god I ended up here. Thanks again!
Yay! I am happy it helped my friend. Science is difficult!
Thanks good video
Best explanation ever!!!!! Thanks so much!!
Amy,,, you are incredible 🥰🥰🥰😍😍😍 adore your videos

True
Nice one Amy
Great explanation!
Thank you
But why does PPO2 go over 1.0? How is it possible to breathe more than 100% oxygen?

SCUBA AMY ah ok thank you for that reply. Very informative response 👍🏻 x
@@amy-scuba great response Amy. I just found your channel and you have some excellent content. Cheers, #SeattleRingHunter
