Question Sore throat and pain when swallowing - symptoms of pulmonary oxygen toxicity?

[Mobulai]

so I don't cook my lungs

Is that why you put your o2 bottles in the freezer
Ok ok I promise to stop clowning around

I wonder if it was just something in the loop then. I hadn’t really done more than wash the exhale loop with water after each day and it had been steramined and set aside for about a month prior to this trip.

That's possible but I'd think if it were some sort of lung or throat bacterial infection it would have lasted / lingered much longer than 1 day. Were you dehydrated at all? That will give me a sore throat for a day or so. Sorb dust irritation? I'm just purely speculating here..

Yeah that’s what I was thinking too. Ah well, the mystery continues…

Clearly need a repeat evaluation with a control sample or two. Perhaps repetitive trials as well, in conditions leaning toward warmer climes conducive to rapid microbe growth. I will graciously volunteer to assist, in the interest of safety, of course.

As the title suggests, I’m wondering if a sore throat and pain when swallowing could be symptoms of pulmonary oxygen toxicity. In my case they appeared after 3 days of dives and disappeared after a day of rest.

It's unlikely that this is pulmonary O2 toxicity. I'd go with either a minor upper respiratory infection or some kind of contaminant in the loop. Is it possible that there was excess moisture in the loop? Did you get any water intrusion?

Best regards,

there was definitely the usual accumulation of spit and some water, though not enough that i'd be concerned about the scrubber or a caustic or anything. most of that ends up being dumped from the exhale loop and counterlung after the dive and doesn't make it down into the can. at this point i am thinking that maybe i had some unrelated respiratory thing going on, and breathing through a loop aggravated it

i was also thinking it would make sense to steramine the loop (again) after it's been stored for awhile, just to be on the safe side

Do you break down your rig after every diving day or do you leave it assembled?

it sort of depends but at a minimum i remove the head and set the scrubber and chamois out on a bench. i'll also remove the exhale loop and counterlung and either flush them with steramine or water. if i'm not diving the very next day i'll remove the entire loop and stermine the exhale side of everything, and occasionally the inhale side as well.

I'm not a RB diver but I found this discussion interesting. Never heard of the product "Stermine", so I looked it up, no mention that it is "safe" for CPAC machines or any other breathing apparatus'. Looks like it more for surface cleaning. Just wondering if that could be the cause??

Or I could be completely wrong and it is always used for breathing applications.
