Has any one ever thought about going to these medical supply stores and picking up some O2.It does wanders for hangovers, drowsiness, impotence, so ive heard and confusion. Just so ya know.

Go to the welding supply and get your oxygen at 1/4 the cost and its the same as medical.
the difference between industrial oxygen and medical is the tank is painted green.
medical tanks must be cleaned and painted by the suppler prior to delivery to a medical facility.
thats what the extra costs are also a way to stiff the older folks who need it and also to rip off medicare.
great for hangovers,
Right on Fred its the welding supply for divers o2. We regularly used welders o2 for in water decompression while diving offshore at the islands.
Hi Mike

Always felt like the broco performs better on medical O2 than industrial. I thought it was because medical was more pure.
Recently came across some material that said several % o2 will increase your burning production. Might want to take a look at some of
john Carl Roats writtings on offshorediver.com .
The industrial standard for industrial oxygen is more stringent then medical grade oxygen. the standard for medical is the requirement of clean cylinders and valves to be cleaned upon return to the supplier.
cutting oxygen is more pure then medical requirements.
The bottom line about the different types of oxygen is in the insurance liability of the oxygen supplier. The gas is the same but the insurance liability is different.
Medical and Industrial oxygen differ in particulate filtration standards and relative humidity (moisture)

Industrial O2 is breathable and has no ill side effects other than it's propensity to exacerbate dehydration.

But remember this all my little frogs and tadpoles-

Decompression is a gas to liquid to gas exchange over a hyperbaric pressure parabola; start messing with the ratio of liquid to solid to gas, and you start affecting the exchange rate... = if you are using industrial O2, drink more H2O to offset lower humidity.
Years ago, gas supply vendors typically maintained two separate storage facilities for oxygen: " welding or industrial or technical" (a non-USP, or illegal to sell for human consumption label) variety and gas intended for human use in respirators or medical procedures (a USP label). Since most gas supply vendors have decided that it is simply not cost-effective to store separate grades of medical gases, almost all oxygen sold in the US is a USP grade (meets USP requirements for human consumption). However, there are distinct differences in how the cylinders are filled.

Typically, when filling an incoming oxygen cylinder, the fill station operator opens the cylinder valve and "sniffs" the valve opening. If acetylene is smelled (an indication of improper shut down procedures in a welding operation), the cylinder is set aside to be cleaned at some later time (to remove the odor from acetylene and thus prevent a potential explosion from an acetylene-oxygen mix within the cylinder). If no acetylene is smelled, then a whip is connected to the cylinder and the "welding" cylinder is filled with USP oxygen.

If the vendor fill station operator sees that a cylinder is labeled as a medical or emergency oxygen cylinder, or intended for human respiration, then the cylinder is evacuated (see below) and filled with USP oxygen.

So, the difference between a modern US "welding" oxygen or "medical" or "respiratory" oxygen cylinder is not the quality of the oxygen gas used to fill the cylinder, but the manner in which the cylinder is filled (and the legal consequences of inappropriate fill procedures) and the FDA labeling requirements.

Grade A is the minimum requirement for USP oxygen. Grade E is commonly called aviator's grade.
