" Researchers have created a new model for predicting decompression sickness after deep-sea dives that not only estimates the risk, but how severe the symptoms are likely to be.

The US Navy Diving Manual may incorporate the model into its next update, as will commercial products intended to help recreational divers plan their ascents to avoid "the bends."

The results appear online on March 15, 2017, in the journal PLOS ONE.

"The current guidelines only give you a probability as to whether or not decompression sickness is likely to happen after a given dive," said Laurens Howle, professor of mechanical engineering and materials science at Duke, who has been working on these models with the Navy for a decade. "This is the first time we've been able to also address the likely severity of the potential sickness, helping divers determine acceptable risk."

All risks have two components -- the likelihood of something bad happening and just how bad that something is likely to be. Having a model that accurately provides both aspects will allow divers to better plan safe depths and ascents to help their bodies adjust -- preventing painful and potentially fatal results."

Best of Show for me this year at Underwater Intervention is Dark Water Visions, The Hammer Head. I was walking around between meetings just looking at what the different booths had to offer. I've been around long enough that I don't get excited by most new innovations. The instant I put the Hammer Head on my thought was: “I would love to burn in black water with this!” After that first thought a whole list of times I was diving or supervising I would have loved to have it came to mind. I started running around like a diver just out of school grabbing guys like Donald Dryden, Les Gorski and Sid Preskitt: “You gotta see this!

Objective: Create an accepted Underwater Oxy-Arc Burning Certification

Why: Because there is none and it is a misused tool. All we have today is suggested practices that have no standing under law.

It's not on anyone else when one of us dies but us. It doesn't cost the company that cut corners on the their job plan, their life. It doesn't cost the company you're working for, that made the cheapest bid, to get the poorly planed job, their life. It is the guy doing the job and remember you took the job.

It is on us!
