==Introduction==

The AltoLab consists of a breathing tube, a cylinder of CO<SUB>2</SUB> absorbent (CO<SUB>2</SUB> scrubber) and a series of foam filled cylinders that hold your exhaled breath for you to re-breathe (mixers). Each mixer is supposed to be around 5,000 feet of altitude, though this obviously varies a lot. A good explanation of the system can be found at http://www.pharmapacific.com/howaltoworks.html
