A: The range of medical oxygen cylinder sizes goes from M-2 to M-250 and includes M-4, M-6, M-7, M-9, M-22, M-24, M-60 and M-122. The diameter sizes range from 2 1/2 inches to 52 inches, and empty weight ranges from 0.7 pounds to 114 pounds.
Nitrogen is relatively cheap. A K size cylinder is less than $10.00 at most vendors. Air is about 79% nitrogen and 20% oxygen. When extracting oxygen for welding gas and medical use the water and other expensive gases are separated leaving dry nitrogen. Nitrogen has demand for dehydrating optical instruments and communication cables, but is still sold more on the basis of costs of inventory and transportation than on any intrinsic value.
