Very well done (on the other hand, with O2 it's easy and quick to do a thing......'well done' :-) )
I want to add something to the O2 humidifiers.

Yesterday I have had an ICQ chat with Bob Kipple about O2. I discover that in USA you do not use humidifiers connected to O2 tanks. (Obviously in the Hospital they have).
This is due to the fact that O2 (in USA) is sold in tank in gaseous form, and not (as the big Hospital tanks) in liquid form.
In Italy every kind of O2 is sold in liquid form.

The O2 in liquid form NEEDS absolutely an humidifier, because the high pressure and the temperature does not permit any presence of water in the tank.

And here start the light disagreement between me and Bob, and ask everyone that knows about this to share.

Kip says: I have used scuba tanks and the water (for humidify the air) is absolutely forbidden there. Also the USA O2 tanks have not any need of humidify the O2. I never have had any probrem with the 2 ones.

Riccardo reply: I agree for Scuba tanks, but O2 tanks (in gaseous form) are refilled with O2 in liquid form. then no H2O enter the tank during refilling.
This mean that the O2 in the tank is absolutely without humidity.

And the O2 without H2O irritate the throat and the lungs.

Now, any of you know how you (in Italy does not exist the problem, obviously) can manage all this?

Thanks for all (and especially thanks to Kip, that has explained at well the situation)
