>>354956 Unsafe? Well, yes and no. Typically, safety concerns in Scuba consist of the questions "can you breathe?" and "do you have too much nitrogen?"
On the latter: With heavy breathing vs. light breathing, you do get a small amount more nitrogen absorbed into your blood, but it's small compared to the buildup of nitrogen based on depth and time. She's in a swimming pool, it seems, so I'm guessing 15-20' tops. At that depth, Nitrogen is not an issue.
So, for the first concern: They make sport regulators, that are designed to allow more air through than most regulators. However, even on a regular mouthpiece, she can probably breathe fine. With heavy breathing, you wind up going through more air; however, at pool depths, a single tank of air can last over an hour.
So I would like to conclude with: I pray to God that I meet her on my next diving trip.
