| CO2 production results
I thought I would post this in hopes of getting some more info on CO2 production and the efficiencies of the scrubbers that are out there. First I will give you a little background on how this all came around. I am a Canadian Navy Diver and was able to take part in a study to help develop a Physical Test that will be given to all Navy Divers on a annual basis to ensure that a proper standard of physical fitness is maintained. I was involved in three tests which helped create a baseline for the group to use when developing the standard.
The first test was the standard treadmill test where I was told to run on a treadmill until I was unable to run anymore. I must also explain that when doing this test I was started at a level that was well above my normal running pace! (that is why the test only lasted 9:50)
The second and third tests were held in a pool where I was wearing O/C gear and hooked up to a pulley system that was around my waist and prevented me from swimming away. I had a reference point which I kept in front of me and as the time increased so did the weight pulling me backwards. We were told to keep the reference point in front of us until we could no longer swim against the weight. One of the tests was completed at the surface and the other was at 6’ under water.
The main reason I put this all together is from what I have read in various posts is that the testing on the Evo scrubber is far beyond what the normal production of CO2 is for most people (2 hours @ 1.6L/min @ 6C). As you can see the results of the test I did showed a CO2 production well in excess of that. I know that the tests I was involved in were a maximal test and one would not be able to maintain that level for a extended time but the numbers are quite interesting. I have to admit that I really do not understand all of the data that is shown here but maybe someone out there does and can comment on the info. So here it is and I apologies if it is hard to read. They are posted in the following order……. Treadmill, surface swim and the 6’ underwater swim. |
