The above graph illustrates the dramatic differences in examples of the decompression times that would be required for diving to the depths for the times shown.
As you return to the surface on the Inspiration, the %O2 increases and consequently the % nitrogen decreases. This results in quicker inert gas off-gassing and greatly reduced decompression obligations.
In real terms, this means with the Inspiration Closed Circuit, a dive to 30m for 60 minutes with only a requirement of about 12 minutes decompression time, is now a realistic dive.
In short, the Inspiration Closed Circuit gives all of the well known advantages of Nitrox but without the problems of pre-mixing, gas switching, carrying extra cylinders, fore-casting the target depth or the depth limitations.
