Question Shearwater Teric CNS% calculation and Air Integration

[Blackcrusader]

Hello, Does Teric AI take account of breathing rate ou tank's air consumption to calculate the oxygen toxicity (CNS%)?
Or does it show the same CNS% value with or without air integration?

I'm a average recreational diver with AWO+Nitrox certification who wants take the Tec 40 certification in order to have a proper training to plan and dive deco dives.

CNS is shown without air integration. By the way you may want to take the TDI Advanced Nitrox Decompression Procedures Course and compare that with the Tec 40. TDI allows to 45m depth on the Deco course. I dive with a Perdix AI without air integration and a Cressi Digital SPG. You will need a device that can act as a backup to your DC as a bottom timer with depth and the Cressi does that. Or a watch and SPG.

Don't we "absorb" more O2 when breathing faster and deeper

Faster and deeper drains your tank sooner, ending your dive sooner, with less O2 exposure than otherwise.

AN and DP is 2 courses. While typically combined, they should be compared to Tec 40 and 45 (which can also be combined). TDI also states this equivalence.

Here Shearwater has documented the exact CNS% algorithm that they use.

Shearwater and the CNS Oxygen Clock

The question of what CNS oxygen exposure is safe can spark heated debate among technical divers. This reflects the seriousness of CNS oxygen toxicity when diving. This article sidesteps that debate, and focuses solely on how Shearwater dive computers calculate the CNS value.
