PFO Concerns in Dive Injury Treatment

If the diver is symptomatic and you are rendering care, then you need to treat the symptoms. Give them the highest concentration of oxygen available, and get them to definitive health care and treatment. Remember that many conditions show symptoms that may mimic DCS. Just because someone was diving does not mean they have a dive-related illness. When creating your emergency action plan, note the location of the nearest emergency room or where and how to access local emergency services.

PROGRAM SPOTLIGHT: DAN Courses 3.0 Update

You are on the boat after a great dive when a buddy team surfaces, and one of them calls out for help. The boat crew helps get the distressed diver on board. Would you know what to do next? Whatever your level of dive training, or even if you are a nondiver dealing with an incident on land, DAN’s first aid training can help you know what to do and how to do it.

Don’t Bite the Hand That Feeds You

With adverse events, there is almost always a cascade in four phases: the trigger, the disabling agent, the disabling injury and the cause of death. Individually, each event is avoidable. Recognizing one at the time of occurrence is an opportunity to react and attempt to mitigate the risk before it becomes a problem. In root cause analysis of adverse events, the most significant factors are the lack of recognition and failure to react to the event.

TRAVEL SMARTER: Travel Document Delays

It’s been more than a year since many divers have traveled internationally and visited beloved or new dive destinations. Although it is unclear when and which international destinations will be fully accessible, it’s important to stay proactive about important travel documentation preparation.

Better Enabling Human Survival

In her work, Rachel Lance, Ph.D., focuses on extreme environments, particularly the effects of explosions. “The human body is fascinating, especially when it fails,” she says. “We are not naturally equipped to survive in a deep underwater environment, so I am fascinated with the idea of finding ways to do so anyway. Perhaps it’s my naturally rebellious side.”

Rescue Skill Modifications

The required skills in a rescue scenario — which involved a surface swim while providing rescue breaths and removing dive gear from the victim and rescuer — were not coming easily, especially if my dive buddy was larger than me. Techniques for rescue diving seemed suited for people with a different body type and skill set — at 5 feet, 4 inches tall, I am a petite woman. Practicing rescues was challenging at best and near-impossible at worst until a course director taught me techniques and modifications that made rescuing more accessible.

Inspecting and Testing Scuba Cylinders

After cylinders first enter service, an annual visual inspection and a five-year hydrostatic test are required. These requirements include cylinders used for diving and other life-support applications and cover breathing air, nitrox, heliox, trimix, oxygen for decompression and argon for drysuit inflation. How are these standards mandated and enforced? What are good and safe practices?

It’s All in the Name

In 1995, when we first explored wunderpus territory, which overlies much of the Coral Triangle, the then-undescribed octopus’ fame had spread far and wide. The newly sensational creatures attained much of their acclaim for dancing like dandies across sandy seafloors on eight unimaginably limber arms — an eye-popping feat of acrobatic dexterity well worth traveling halfway around the world to see.

Sound in the Silence

Audible cues and signals can get your buddy’s attention, signal a group of divers or indicate a problem you can help address. Even though we may dive to escape the noise of everyday life, we need to pay attention to the sounds around us. Doing so could make your dive even more special because your buddy got your attention to see something remarkable — or you may even save a life.
