Denisegg's incident and near miss at Jackson Blue

[DocYates]

Wow, excellent example of something we rarely see. I am glad you are OK and on the mend, and I hope you get back to diving soon.
This makes you wonder how many diving deaths may be attributed to something like this, and get written off as a "heart attack". The foam at the mouth is a classic example of pulmonary edema. though, pulmonary edema can been seen in lots of case, such as coronary artery disease with congestive failure, etc, it can also be seen in simple drowning. In this case it was Denise's own fluids that were drowning her though.

Interesting information... I will have to check just how much pressure my mechanical positive pressure system tolerates before the bleed back (safety release) valve activates. It delivers 100% on inspiration of activation of the button on the delivery head......I don't know if this particular system is available to the general public in North America.

The Soft Bag with Reservoir is getting to be the more popular system here in Occupational First Aid levels and higher. Last dive emergency I assisted on .. we wound up assisting vents with a SBR (BVM)

I would think that the "Assisted vents" taught in higher level courses .. Industrial First Aid... Paramedics and higher would be beneficial in this situation. Basically it involves hooking the tubing to a Pocket Mask and gently blowing through the one way valve timed with the patient's breathing. This method while not exact can create a gentle pressure and if the person is trained practiced at it.. they can get an idea of how effective it is.. It would certainly give a much higher O2 % although I am not certain exactly what percentage.. I will have to search through my books for that info

The Pulmonary specialist I am seeing Friday was recommended by DAN. I am sure he will want to get the results of the tests performed on me taken in the hospital before he is willing to even begin to make a diagnosis, but I will report on what he tells me.
The doctor I saw on Monday didn't seem to believe that the series of dives done over the weekend or the elevated thyroid had anything to do with what happened to me on July 4th.

Okay, that sucks to basically be back to "haven't a clue why it happened".

Since oxygen sat is essentially 100% with air at 1ATA, and that is with a typical 4% - 5% drop in oxygen - normal expired air is 16% - 17% oxygen - then breathing 100% oxygen should still only use 4% - 5% and the exhaled oxygen content could be expected to be 95% - 96%, with the rest being CO₂. Pretty good, I'd say... you might get a percent or two lower because of offgassing Nitrogen for a while, but my bet is that you'd still get a good 90+%.
I'll have to hook up an analyzer and run a test & report on that

Denise...God love ya GF! I am happy to know that you are still with us in every way! Your training and your buddy is what got you through such an ordeal! All I can say is thank you to everyone who had a part in keeping you with us! I love ya girl!

On a side note...D...when you had that awful dream back at Vortoberfest last year...was that a possible premonition of something to come? I hope you will be back at Vortoberfest again! It's definitely not festive unless you are there! XOXOXO

That would be very helpful Rick....I don't have the resources to run that test and I haven't been able to find any solid answer in my books so far.

if there is no info on this out there, this may be something DAN might want to know about too
Thanks Petunia, Rick

@denisegg: Ask the pulmonologist on Friday whether it's possible that a subclinical or mild hyperthyroid condition could predispose a person to pulmonary arterial hypertension and other cardiovascular dysfunction. Thinking along these lines, it's really not so far-fetched to imagine development of pulmonary edema.

 

[TSandM]

Unfortunately, my guess is that neither the cardiology folks nor the pulmonologists will find anything wrong with you. In reading the literature on this entity, when it has been recognized, there has rarely been any underlying cardiopulmonary dysfunction identified in the patients. Even the link to hypertension is weak, as there are definite cases where hypertension was not involved.
