You could stay down until you are saturated. That would be days for the slow tissues, bones etc. Then when you came up it would be the equivalent of traveling from sea level to about 7,500 ft above sea level.

Also,
You would need a mix of 36% or greater to have a ppN2 at 8 ft less than ambient at sea level.
