I have the original VR3-kit from ISC on my COPIS-Meg, cable plugged into right lung, the little K1d cell.
The cell calibrates perfectly on air and O2 on the surface.
When diving, the VR3 show _really_ high ppO2 (like 2bar+)

Is this a design-flaw?

My thougt was that either
1. It is something wrong with the cell/vr3/something
or, more likely
2. The cell is located in the right lung. In the bottom of that lung, O2 is added, as this is a COPIS-meg. ON the top of the lung, the T-pieces are, and gas flows through when I breath.
As gas goes the path of least resistance, why should any mixed gas force itself down into the lung ?
If so, all I measure, is high ppO2-content that is at the bottom of the lung, sometimes flushed even more with pure O2.

Am I right or what?
