helium is low density gas and it reduces the resistance to airflow

A is correct
1)Helium is less soluble,less is dissolved in tissues
2)It diffuses more rapidly
3)Has a low density ,decreases work of breathing

All I know is that its something that forces N2 bubbles back into solution and reduces the volume of N2 bubbles
Prevention is a SLOW ascent after diving

This is new- I hear that if the diver gets the bends one way to recompress him is to throw him back down to 66 ft (2 atmospheres) or put him in a hyperbaric oxygen chamber (but these are Hard to find)
