Second Stage Regulator
What will happen if you don't keep exhaling if u lose ur second stage regulator?
I am gonna learn to scuba dive at Mermet Springs (Southern Illinois) this July and i was reading my OPEN WATER DIVER workbook and I saw that you shouldn't hold ur breath and I was just wondering why? will ur lungs explode or sumthing?
As you will learn in your SCUBA class, if you ascend while holding your breath you could suffer a lung over expansion injury which can be fatal. Your lungs don't 'explode', but air is forced into your tissues and blood stream which can cause an embolis that can cause a heart attack or stroke. That is why you are taught to aways exhale when the regulator is out of your mouth. You will also about how, due to the equal pressure of air in lungs at a given depth that you can indeed exhale all the way to the surface and still have plenty of air in your lungs. This is known as an emmergency swimming ascent.
