Joe Cocozza (sat to the left) interviews Dr Simon Mitchell on pre breathing a rebreather

 

In July last year I wrote a LinkedIn blog calling for Auckland based divers to take part in a rebreather study that was being conducted by Dr Simon Mitchell and Dr Neal Pollock.

The results of this useful research were first unveiled to the world in September 2014 at EUROTEK, the European Advanced Diving Conference. Dr Simon Mitchell presented ‘The Five Minute Prebreathe: Sensitive Test For CO2 Scrubber Problems Or A Waste Of Time‘ to a packed hall of international delegates.

Since then there is some mixed messaging about should rebreather divers do a prebreathe? Or is it just a waste of time? If you didn’t attend either EUROTEK or OZTek and hear Simon Mitchell’s talk, what should you be doing?

Joe Cocozza of Pod Diver Radio interviewed Dr Simon Mitchell at this year’s Beneath The Sea show about this hot topic.

During the interview Dr Mitchell stated, “this study has been mis-interpreted by some people to suggest that the prebreathe is completely useless. We are not staying that. We absolutely believe that a prebreathe should be still be done for the other reasons. Checking the loop function is correct, adding oxygen and maintaining a set point. These are all critical things.

What we are saying is that you should not do a five minute prebreathe in the expectation that it will reveal any carbon dioxide problems. Or put it another way, if your five minute prebreathe is ok or appears ok from a CO2 point of view you cannot rely on that. That is the point we are making. Of course you should always do a prebreathe.”
