Here's a possible skin bends incident for analysis.

Dove my regular dive profile (drop down, hang around, make my way slowly up taking pictures all the way, added fighting in the particularly strong current for photography with new strobes with added drag and task ppadiloading, became dark narced, cut my planned bottom time short by 10 minutes and breathed an extra 20 cube of gas in the process.

My table based air dive plan included deco, my backup computer x1 computer set on set on +2 conservation suggested 20% more deco. I added 30% extra at 15ft since it was a strenuous dive and I hadn't felt right.

20 minutes after surfacing the skin on my stomach, back and sternum went mildly but distinctively marbled red/purple. I wrenched my arm exiting the water which added joint pain and my bad knees hurt always. So DAN referred me to get checked out. I could have had a chamber ride but opted for o2 instead.

A day later no symptoms presented besides feeling exhausted and a sore throat from 4 hours dry o2. Still considering it an unexpected near miss.

Only other factor I can come up with was was biking before the dive and maybe didn't hydrate enough.

It was a dive profile I do regularly with more bottom time normally and yet this is the closest I've been to considering myself bent.

That is all.

Cameron,

Heavy work on the bottom and being cold on decompression are two known risk factors for DCS. You didn't specifically mention cold but if you were diving near your home I'd wonder if maybe you'd been a little chilled.

Bluish/purple marbled skin is one sign of DCS. The fact that the rash resolved on O2 makes it more likely that that's what you had. The technical term for this type of skin rash is cutis marmorata. Cutis is a different kind of rash than the "Type I" hive-like skin rash that can also occur with DCS. It is considered a more worrisome DCS symptom because it is often accompanied by severe neurological DCS. If you had presented at our facility we probably would not have offered you the option of surface O2 but would have recommended instead that you be treated with hyperbaric oxygen. DCS symptoms that resolve on surface O2 frequently reoccur after the O2 is discontinued, and those symptoms are often worse or more varied than the original ones. I hope this doesn't happen again but if it does, I strongly recommend you opt for treatment in the chamber.

Best regards,

I was always told any symptoms that present them selves on the trunk of the body are to be treated like type 2 DCS, even with no other symptoms present them selves.

I am glad to hear it was only a close call and not a real hit. I would also take a few days off from diving just to be safe.

I have a good buddy that was almost paralyzed from a hit, he ignored his rash and then the next dive he was cut short on deco (this was diving commercially, 100' or so, way more aggressive profiles than navy tables, "Z"ing out every day ect). He was getting treatment every other day for about 3 months until 90% of his symptoms were resolved. He still cant really feel his feet.
 
Can't "like" your post so just want to say glad you are ok.
 
For sure I'm staying topside a while, thankfully my livelihood doesn't depend on me being back in the water ASAP.

Sorry to hear about your friend. Sure changes life quickly.

I am grateful I am ok and there was no complications.

And thanks for posts.

Regarding the dive profile, it's unremarkable among dives beyond recreational limits go but within my experience and training. I'd rather not share it on the forum with my name attached at this point. I'm still new here.

Regards,
Cameron
