Hello all,
Ive had a few discussions lately about the effectiveness of scrubbing off with a high ppo2 mix during a series of deepish no-stop dives and would like to hear more opinions. So far, the benefits of more complete outgassing and shorter surface intervals are weighed against increased equipment/task loading and the hazards of hot mixes at depth.
I understand that breathing 1.4-1.6 pp02 will create a large pressure gradient resulting in more efficient outgassing (o2 window),- what I dont understand is how effective (or ineffective) breathing, say 80% for a 5-10 minute during a series of dives would be Ive ran some vplanner scenarios with minimal results- does anyone have any empirical evidence as to the effectiveness of so-called scrubbing off
Thanks for the help
Steve
