Semi-closed and Fully-Closed Rebreathers are not the same. I thing it 
would be beneficial for discussion purposes and design requirements if 
they were looked at seperately. Semi-Closed Nitox Rebreathers, and any 
time you discuss semi-closed, you are talking enriched air, are a small 
step up from open circuit compared to fully closed. A correctly designed 
semi-closed system, so far not available yet, can be as safe as open 
circuit and would not require electronics or an O2 sensor. However, the 
design requirements for fully closed are complex, require a lot of 
redundancy and of course electronics and O2 sensors. And they greatly 
increase the risk of death.
