You have to be careful with things like that. There's a lot of pressure underwater. When you surface, everything in you wants to expand, including the air on your lungs. Surface high enough with your lungs full of air and the lungs go pop
I don't think you could get deep enough and still be able to breathe through an tube/hose for that too happen. If it's just a tube, it's can't be very long, otherwise it's just like rebreathing the air in a bag. It also takes more effort the longer the tube is.
I mean, you have to be a lot deeper than 4 meters but yeah, they literally will pop. The pressure will condense the air youre breathing. Its greater than the energy making the molecules ping around, if I remember correctly. As you come to the surface the pressure lessens and the molecules will start bouncing off each other and will force more space between them. Essentially, the air you breathed in will get considerably bigger than your lungs.
The advice is to breath as normally as you can. Oh, check out submarine escape suits if anyones interested. They work on the concept.
One of the major rules of diving is to never hold your breath. If you’re deep enough for it to matter, as long as you’re exhaling as you go up you’re ok.
