> "but will the regulators work correctly at high altitudes?"
I got through to a technical person at Precision Medical where the Easy Pulse 5 you mention is made. The answer is "yes", it will work fine above 10K. The reason they put 10K on the spec sheet is because they test their products within specific ranges and in the case of their medical regulators they don't expect the user to normally go any higher than 10K.
So that concern is put to rest, at least in my mind.
This and the other pneumatic pulse regulators are really a fine solution for stretching the oxygen supply and avoiding waste. Getting a tank re-filled "on the road" can be a hassle so an oxygen conserving regulator such as this EP5 seems like an excellent idea.
