Two breathing Q.

[milosusa]

Please, don't be to mad, if those Q's are little stupid, but I like to ask anyway.
It is normal, if you turn on your back under the water to feel like is a harder to breath thru regulator ? Or is something wrong with second stage regulator ? And second Q. i know you should never hold your breath, but going over the reef I try couple times to hold my breath little longer a swim over it without puting any air to the BC, I would say 2 -3 feet elevation different max. Is this dangerous to the health practice or it is OK to do it sometimes ?

Yes if i'm not mistaken the answer to your first question is that that places the 1st stage of the regulator at a point lower than your lungs and airspaces. While no one will ever reccomend holding your breath as it is dangerous, it is more dangerous if you are on an absolutely full lung volume as compared to a partial lung volume that is normal.

-Yes, breathing performance by design will change in that position. Nothing is likely wrong.

-Officially if you are not inhaling or exhaling than you are technically holding your breath. Practically almost all divers “technically” hold their breath at some point.

Do you mind me asking what agency you hold certifications with? I know one of the skills you practice in a PADI class is actually breathing on your back, so you can see how different it feels.

I don't recall doing that in my PADI OW class....

I could be mistaken, or my instructor could have skipped over it, I don't know, but I don't remember us ever trying that.

That's because it's not in the PADI standards.

maybe I am different but there is no noticeable difference whether I am on my back looking up or on my stomach looking down. I have ScubaPro Reg, MK11/R295. Love it. Cant understand why people get those fancy smancy ones with the dials.

That's the first time I hear of that skill. Perhaps it was phased out years ago?

 

[dmdoss]

But by puting the first stage lower the pressure should increase on it. This should make it easier to breath, even if only by a foot. Since the 1st is on bottom it would breath like you were deeper. Right???

The skill is certainly not required for PADI, actually dont recall even seeing it listed, although when we go down the first time and were talking about breathing underwater I give it a mention.
