The decompression model

Divers plan their decompression stops around a model of how gas dissolves into and out of the body. Get it wrong and people get hurt, so the planner has to be right, every time.

  • The full Bühlmann ZHL-16C model with gradient factors, the dissolved gas model used in technical diving
  • All 16 tissue compartments worked out at every step of the descent, the bottom time and the ascent
  • Air, nitrox, trimix and closed-circuit rebreather dives, with deco gas switches
  • Altitude, for dives in mountain lakes
  • Several days of diving, with tissue loading carried from one dive to the next
  • A profile for each diver, with their own gas use and conservatism

Why we built it

Bubble Deco is safety-critical maths, done carefully and run on the device, and published and maintained in the app stores by us. It is the same work we do for clients, from the calculations to the store listings.
