How Much Is In Your Loop?

Although alluded to in your initial rebreather training, the idea of ‘optimal loop volume’ escapes some divers. Even among advanced rebreather divers, the loop appears to be managing them instead of them managing their loop. They learned to cope, instead of, to control it.

When this occurs, we are talking about a Right-Left Shunt, RLS and a potentially increased risk for developing Type II DCS. There are other sources that,
