I remember a few years back there was a German or Austrian called Heimo Hanke (?) who trained using a recompression chamber before doing his dives in a cold winter lake. He was doing 4 minute statics at very heavy pressures, then doing safety stops on 100% O2.
I think.
Maybe Patrick is doing the same?
