There are several studies of this type spanning several years usually with Dujic somewhere among the authors. A key concern is exertion at depth, or after the dive during the period of offgassing. This is of high concern for technical divers who have a lot of equipment to be lifted off a dive...

Sorry to read. Any article on pneumothorax can help. DCI typically means DCS and barotrauma. Pneumothorax isn't related to the physiology of DCS, DCI as a term is used when both types of injuries occur to an individual from the same dive. en.wikipedia.org/wiki/Pneumothorax In the stated...

The position you assume on descent has no practical physiologic significance except if you can't equalize your ears to match your descent rate. The easiest descent is done either upright or horizontal in terms of opening the Eustachian tube. But many can do head down without issue, as is...

Nothing scientific has been added to the literature beyond what is posted here. I descend quickly to spend most time at the bottom, it did take some time for me to learn rapid ear equalization. I descend over 100fpm and will slow down only if my buddy cannot follow, and I dive open circuit.

Pacemaker makes and models have different depth ratings, but this feature is almost never considered at the time of placement. At minimum you need one rated for the depth of your intended diving and then clearance from the cardiologist to dive for whatever the condition the pacemaker was placed...

Unfortunately, autopsies are not often made public, in the US its only available for criminal events and often censored for public sensibility. Investigations are just best guess reconstructions to explain all the available facts, the more facts, the better the reconstruction particularly...

I was in the area May 2014. Another fact was it was the 3rd dive of the day for the group, and they were at Chac Mool near closing time. This summary is as Steve Gerard posted in his blog and posted on this thread earlier: Steve's Info Deep Horizon Blog " ... On Thursday evening, April 19th...

Cutis is a bad prognostic sign, it means severe DCS and higher fatality risk. MMS: Error Taken at the scene ~ 12 hours before fatal outcome despite recompression.

This study reinforces the relationship of microparticles to bubble grades in humans. Thus, if this could be made into a simpler blood test, we could measure decompression stress without dopplers. Doppler used requires a trained technician and an echocardiogram machine but blood assays can be...

.. typically 4-6 weeks to recover from the TT6 hyperbaric exposure.

You can check archives from SB and TDS regarding these discussions from the early 2000s, there are studies, my pen name is linked to most of those freely available discussions. I've also archived the accidents on divingaccidents at yahoogroups. I commented and discussed with DAN that the...

The hyperthyroid state in Graves should be resolved before return to diving; besides cardiovascular risk there is a risk of accelerated oxygen toxicity. Once the hormone levels are normalized, as well as all signs and symptoms abated, you should also see a diving physician to cover all the...

Some questions I'd raise, I did not read the whole paper: Divers selected had prior diving accident history. Did this select population have some form of ETD before their accidents that contributed to their risk of a diving accident or did an accident lead secondarily to ETD in previously...

It reads like you have the skills and facilities to manage these conditions. I do not know of a published relationship between diving, HH and bleeding, but as knotical suggests, known association between all 3 is aerophagia: it aggravates HHs, aerophagia is common in diving, so its inferred HH...

An unusual situation worth some comments. If your diving caused any laceration to your UGI, which was of insufficient volume to cause hematemesis [blood is a good emetic], you'd notice it as hematochezia. A heme test is considered pathologic unless proven otherwise and can easily be done at...

Its hard to wipe entire boats down, but a captain and crew's should consider they are most as risk since they are on the boat longer than their guests. For guests, I'd just recommend you wipe down your rooms yourselves just in case, and spray any wounds you get with vinegar. The Odyssey had a...

Its a stock photo from Wikipedia, to avoid copyright issues. There are various cases of strep fasciitis reported in water sports by small gashes that went out of control. Appearance is similar to the photo: redness, swelling, then black splotches as tissue falls off, moving upward in the...

If this is a true story, its a fairly serious case of being colonized by a virulent strain of Streptococcus that is living in the boat. Given the flux of divers and crew in and out of liveaboards, it very possible to carry organisms into the boat that eventually stay there, and they can come...
