How does helium prevent divers getting the decompression sickness?
When air is breathed under pressure, nitrogen dissolves in the blood. When the pressure is relieved, the nitrogen comes out of the solution as bubbles, which affects the circulatory system, causing caisson disease or "the bends". Helium dissolves much less and decompression is quicker.
How much can I lift with helium?
You need 0.975m3 (or 0.165 kg) of helium to lift 1 kg. So rounded up you need to plan for 1 M3 of helium to lift 1 kg.
