I doubt that we're risk-free either way. But I wouldn't be squatting over 400 if I weren't pressurizing my internals. Like you, I'll stay oxygenated: you saw the results of the experiments with - what was that called? - using balloons to cut off the oxygen to the muscles? It didn't do any good in the end result.
Matter of fact, I tend to suck a lot of air to oxygenate my blood before a set. I'll hope now that it possibly will alleviate aneurisms to the brain or eyes. Aneurisms are a danger for us older lifters. Funny how we never hear of strokes or any such things, but here again, it could be that there are more injuries out there than are reported.
