| Re: O2 slug
I've read a lot about the potential hazards of having the O2 bypass valve on the inhale side and the "theory" behind it but... has anyone validated this theory in any way? Have there been any recorded close calls or incidents of oxtox that were or could have been related to having the manual O2 valve on the inhale side?
Since it's not nice to reply with a question here's what I do. I dive my Meg with "the theory" in mind and being a bit paranoid about this issue I force myself to always take a deep breath before I manually inject O2 and push the button on an exhale cycle hoping I force some of the slug through the loop to give it a chance to dilute. I haven't bought into the connecting the O2 to the exhale CL yet for reasons previously mentioned in this thread or other posts. Keep in mind though that the deepest I've been on the Meg (while manually holding a setpoint) is 140ft so I don't know if this is acceptable for deeper stuff.
Regards,
Tibby
