Any pressure regulator supplying a constant pressure...

There is definitely a potential surge problem there.

The EDS regulator is special in being designed to switch from no flow to lots and back while keeping the output pressure reasonable.

If you wish to gamble with yourself, then perhaps a surge tank after the regulator to improve the odds. A pulse-ox to keep an eye on the contraption might also be a good idea. But the words 'good idea' might not fit the situation?

From what I'm reading, it seems most medical "yoke-style" (CGA870) regulators are rated more for gas FLOW, i.e. Liters per Minute, than for pressure, i.e. PSI. It is hard to find the PSI rating for these medical regulators, but one data point I found was that one was rated at 50psi, which is much higher than the EDS unit is designed to handle. It is the typical regulator where you can dial the FLOW from 0.5lpm to 15lpm. I realize that FLOW and PRESSURE are two completely different animals, but they are related and affect each other. Is there a way to set the FLOW rate to get the PSI at the desired 15-20psi? My gut tells me not really, but my physics is a bit rusty and can't prove it to myself.
