Close Call; Glad I could write this incident report.

Any links to the Beta Blocker studies or sources?
I am on a very slight dose as well but would be really interested in knowing more about the possible link with IPE.
I am a cave diver / deep diver who would rather pass on any problems!

To be clear, it has been mentioned; I don't know that it has been studied. Here's a couple of mentions, and my Google search shows a reference on Rubicon, which my computer warns me in dire terms not to click on:

From what I heard, no one knows exactly why someone gets an IPE. Glad you are okay. Makes me rethink my solo dives. Sounds like without assistance you would have died. Thanks for the write-up. Cheers

Glad you got a clean bill of health. The only thing I could suggest (and I'm still a newb) is an air horn (someone suggested to bring on a liveaboard)? I can see how it would be difficult to blow a whistle if you can't get a full breath, but if you can locate a horn you can make a lot of noise without a lot of effort. SO glad you're ok.

Hopefully Lynne will see this and opine in.

Very scary esp. when you're diving with a gas that has a relatively high % of O2 for the dive. There had to be plenty of O2 available to your body except for the edema in the lungs.

Here's the link to DAN info. http://www.diversalertnetwork.org/medical/articles/Immersion_Pulmonary_Edema

My first dive went off without a hitch. I was diving 33% nitrox; po2 set at 1.5. Went to 103' max depth for a few minutes, then ascended to 85', then to 75'. Because of the 1.5 po2 setting, my computer made me do a 2 min. deco before shifting to 3 min. safety stop. I was aware that that was going to happen. Total dive time was 38 min...​

After a 1 hr. SI, went in for the 2nd drift dive. Used 35% nitrox. Max depth was 85' but most of the dive was at 75-65'. Another great exciting dive. ...After about 25 min. I started my ascent. Again, computer required a 2 min. deco and and then did a 3 min safety...​

IPE = Scary stuff. Excellent job by the surface support, and I'm glad you're okay. Any chance you'd be able/willing to share the dive profiles from the computer?

Thanks for posting this. Hopefully we can all learn something from this. I am very glad you are still with us!

This is a really scary entity, because it can occur on any dive (or sometimes just swimming) and nobody really knows why some people get it and some don't, or what the llikelihood of recurrence is. Duke is studying this problem, but I believe you likely fall outside the age range for their formal study. Nonetheless, they may want to get some data from you, and I would suggest PMing Duke Dive Medicine and asking him if they are interested in talking to you.

Wow, what a close call. Glad you're ok. Here is an article on Immersion Pulmonary Edema if you're interested. Scroll down to page 4: http://www.underwatercouncil.com/downloads/newsletters/current_newsletter.pdf

Interesting article which talks about a lot of risk factors.

It refers to is thyroid drugs which may increase blood pressure and then also erectile dysfunction drugs. But don't ED drugs like Viagra lower blood pressure? Isn't Sildenafil even used to treat pulmonary hypertension?

And also why Sildenafil and nitrates can't be used together because of excess drop in blood pressure.
