I just heard from someone who used to be a dive master and is now in medical school (not here, he's in the States).
He has told me that there is a correlation between using a snorkel and CO2. What he said was because when a swimmer or snorkeler breathes in and out and because of the width and length of the snorkel tube, that CO2 remains in the bottom of the snorkel so when the swimmer/snorkeler takes each breath, he is inhaling the remains of CO2. This is not a good thing.
Is this why, maybe, that when using a snorkel it appears a swimmer/snorkeler can't get a good breath? I also know that because of the small tubing size, it is hard to really hard to inhale a lot of air, or at least that has been my problem. But CO2?
Is this why when using a snorkel for swimming or snorkeling, breathing can be difficult for some? I know Warren said he uses one, I'd be interested to hear if he has found any problems with using it.
Anyone else?

I got a snorkel about three weeks ago. I havn't had any problems with it. But it is harder to get a good breath. I only use it for drills like one arm free and catchup drills so I'm not really breathing that hard becuase its low effort. A snorkel is definatly good for drills, I like it.
