Interesting. Thanks for the discussion. I guess the lung irritation from dry gas would have been true of any gas (e.g. air) with (maybe) some fractional additional contribution from the higher P02s. The corneal edema is interesting/suggestive and probably not dehumidified gas related.That's my conclusion as a former USAF hyperbaric doc and retired cardiac anesthesiologist.
Sequential T6's are not wholly unlike 47 repeated sessions at a PPO2 of 1.2, or spending several days on a high PO2 ventilator with dehumidified gas. There's a tiny bit of oxidative stress on the lungs, plus the repeated dry gas exposure. My slight dry cough was indicative of that. I'll concede that the whole symptom complex may just have been alveolar dessication since my mouthpiece bypassed nasal humidification, but I personally think the high PPO2 played a small role. Symptom onset may have been sooner, but not noticed since we were so active. But arriving home and lying about, the slight cough became more noticeable.
@Duke Dive Medicine ?
Wait this is _still_ out there? Such an overflow surely must have been fixed alreadyGarmin dive computers have a design flaw where they store the CNS% as an unsigned 8-bit integer (uint8). I've seen mine hit 255% on a dive and wrap around back to 0%, which is kind of hilarious
Hard to say given that this is secondhand information. Did you mean elbows plural? Bilateral pain could be indicative of a spinal/nerve hit, so if that's the case, then possibly. Was she treated in the chamber, and did the symptoms resolve? What about the tingling in the feet?Totally a side track, but this reminded me of the student of mine that got bent on the 100' dive of AOW. Very much an "undeserved" hit. We'd been diving several days in a row, but no more than 2 dives per day to less than 60' and this was the only dive of the last day.
She was diagnosed with a PFO (as I suspected). As you noted, she presented with sudden symptoms. However, it was "classic" pain in the elbows rather than neuro , skin, or inner ear issues. We had literally just stood up (after swimming to shallow water for the beach exit) and she immediately said "ow!" and said her elbow hurt. The victim did later develop some tingling in the feet, but only in the ER several hours later.
Would she be an exception to the rule?
I got a couple of basic questions, what is a T6?T6 per day
Not older, just better.Maybe I'm just getting old.
T6 refers to Navy Treatment Table 6. REPEX is a whole body oxygen toxicity (dosage) schedule developed by Bill Hamilton and others many years ago. Nothing to do with WOB or exertion.I got a couple of basic questions, what is a T6?
Also whats Repex?(guessing that is respiratory exertion) :clueless:
