Title: O2 bubbler question
Post by nani on Feb 27^th, 2006, 11:28pm

When my hubby had my tank refilled at the welding place, a discussion about welders vs medical O2 came up. The guy said the only real difference is moisture content. He said welders O2 can have more moisture. Is that true? If it is, then should I still use a bubbler? I'm living in the desert where most days the average humidity is in the negative numbers...

Hi Nani,
It's Howard Clustervilles Resident Respiratory Therapist / Pre Med Student. No you can’t humidify a Non Re-breather nor can you a simple mask. This is for a couple reasons one is because of the liter flow needed for both is too high for the bubbler and two moister will disrupt the valves and reservoir bag on the NRB. I am afraid that drinking more H2O is gonna be the only way to compensate for the drying out that you might be getting from the O2.

The medical supply place I use advised against it and seeing as how I listen so well...I tried the bubbler thing.

First I tried a home made mayonaise jar bubbler. At 15lpm, the bag got wet and the valves stuck. Plus, it seemed like the flow rate was cut way down by the moisture. Didn't like that.

Then I tried a "real" bubbler from the medical supply house - same story.

Iron (steel) + oxygen --> rust

So why don't we hear all the time about exploding rusted up oxygen tanks?

Because some water must be present for rust to form. Therefore, oxygen under high pressure, be it for medical or welding use, must be absolutely free of water. My tanks come with a leaflet that says: water content less than 0.2 ppm. Even scuba divers who fill their tanks with plain air, including all pollutants, must make sure to remove all traces of water.

In the lung the air (or oxygen) must be saturated with water vapor. If you want to supply all that water from your mucous membranes in your nose and throat it's your choice. I use a bubbler to combat drying out my membranes. I've never seen a drop of water in the 30 feet hose nor in the reservoir bag, even less I ever had water clogging the valves.

Ive been using a bubbler with a non-rebreather mask for years with no problem.

Although, the first time I used it I filled the bubbler more than half way with water, I almost drowned.....LOL ;;D

Now I just fill it one fourth of the way and there is no problem what so ever!

Gator, drop the water level down and give it a try, youll be amazed ;)

You can do without a bubbler on the welding tank, but it will dry your throat and nose out badly.

I always use one, and like they say......DO NOT FILL MORE THAN ONE QUARTER FULL. It will go everywhere.

Now, I have blown up a bubbler with my welding 02.....had the pressure just a wee bit high.
