One of our primary goals is to widen the use of Hyperbaric Chambers to increase diver safety on yachts.  Moondog Dive Outfitters offers hyperbaric chambers for sale and lease.  We have certified chamber instructors through IANTD and offer courses regularly.

These fully accredited 40 hour course certifications are issued through an international accreted training agency. Andrew Driver has had years of experience meeting the specific concerns and requirements of Yacht based Hyperbaric programs. Please feel free to contact us for references.

Portable Hyperbaric Chambers for Divers

Training-and-HyperbaricAs rebreather and SCUBA related expeditionary diving on yachts and live aboard dive boats becomes more popular many individuals are pushing the boundaries of fitness, equipment, ability and physiological understanding. Often dives are undertaken in locations a long way from appropriate help should Decompression (DCS) strike. Even an experienced, well trained, well planned team must realistically expect a DCS incident at some point. Portable hyperbaric chambers / stretchers are an excellent and now affordable option to cover this eventuality. To learn a little about this technology, to purchase or lease a unit or to get training in the use of chambers please read on.



The New SOS Hyperlite Hyperbaric Chamber

hyperbaric-communication-2Blue Foot Diving is proud to offer the SOS Hyperlite Hyperbaric Chamber.  The new Hyperlite is truly innovative, quick deployment, first aid medical equipment.  The product of newly developed technology, manufactured using modern high performance fiber materials to their best advantage.

Like a hyperbaric chamber, it provides 100% oxygen on demand through a BIBS mask or hood, whilst pressurized with air and is suitable for use anywhere from diving sites, remote locations, war zones, medical centers, and ‘one the move’ in aircraft, helicopters, yachts, submarines, ambulances and other road vehicles.

The overriding advantage of the Hyperlite is its lightness, fold ability and versatility.  These are very significant benefits where inaccessibility, inclement conditions and/or other dangers may be present at an accident site.  Treatment starts right there, with final resolution likely to be some way away where specialize hands-on medical support is available.

Why you need to act quickly!

hyperbaric-maskMost divers know or should know that decompression illness is best treated as quickly as possible! Twenty to twenty five minutes after a DCI incident you are no longer treating the bubbles more the damage done by those bubbles. The longer the damage goes untreated the less likely a perfect and speedy outcome becomes. The Navy and the commercial dive world have long recognized this. It is standard operating procedure that they have steel chambers at their disposal and can have their divers immediately recompressed for injury or decompressed as part of their dive plan. Quick treatment allows a return to diving in a short period of time because the injury was treated quickly and little damage done.  Alas the same is not true in recreational technical and expedition diving. Often incidents go untreated or if a chamber ride is undertaken it will usually takes many hours and in some cases days before hyperbaric treatment is administered.

Of course the above paragraph refers to differing levels of decompression sickness where many cases can be completely cured even if DCS is delayed hours. In the case of a serious POIS (pressure over inflation syndrome), an example being an AGE(arterial gas embolism)  this is not the case. The consequence of a delay of more than minutes can be paralysis and death. We have all heard of individuals coming to the surface seemingly fine only to hit the deck seconds later and never recover. In these instances the only way to save someone’s life is to have a chamber on site.  I chartered a vessel once when a crew member came directly to the surface from 240ft his only chance would have been a chamber aboard. Alas that was not the case.
It is now possible for yachts, live aboard dive boats and expeditions to apply the same logic and procedures that the Navy and commercial dive setups use by having a chamber on site.

Available now for purchase and lease through Blue Foot Diving are a number of chambers that can cover different applications and size requirements.

The latest and greatest (and it is) on the portable scene is the Hyperlite unit.  This chamber designed in the UK and manufactured in the USA has undergone the rigorous certifying process that makes it the only compliant ASME (American Society Mechanical Engineers) and PVHO (Pressure Vessels for Human Occupancy)

In short this means it is the only portable light weight chamber one can legally use in the USA and Canada and on their flagged vessels. This has been a huge issue in the past with other manufacturers portable chambers. This chamber is small portable unit that can be used for the Navy tables 5 and 6 which are the go to tables in 95% of all decompression cases.

Hyperbarics 101

hyperbaric-interiorIn this explanation we will be referring to diving decompression injuries. However HBOT (Hyperbaric Oxygen Treatment) is being used successfully for other medical applications such as wound care, traumatic brain injury and carbon monoxide poisoning to name just a few. Feel free to contact us with other applications for Hyperbaric systems.

Hyper means greater than normal, baro (baric) means pressure. By putting someone in a chamber we apply them to greater than normal pressure and can treat dive injuries using the same physics that caused the DCI in the first place.  In essence a chamber ride is a dry dive.

By pressurizing someone in a chamber, and administering a high partial pressure of oxygen (PO2) we achieve 4 major things. (5 if you are a medic or doctor)


  1. The bubbles that still remain are driven back in to solution so they can slowly be released without causing damage.
  2. The patient is put on Oxygen, usually at 60ft for diving incidents. This has many benefits; it creates a gradient between inert gas in the blood and tissues which helps wash out the inert gas. Tissues that have become ischemic (lacking in blood flow) become perfuse with O2 as it is carried by Hemoglobin and in the blood plasma itself. Healing is accelerated and edema (swelling) is reduced.
  3. Patient is hydrated, this insures a good blood volume allowing better transportation of gas and waste products from the body.
  4. Time. We buy time to allow the patient to off gas and the injury area to become oxygenated and healed
  5. Administer drugs when necessary.

If you are interested in learning more about Hyperbarics we regularly run courses for divers through  IANTD, and Wound Education partners.

We offer yacht based courses with both hard and portable hyperbaric chambers. Remember, if in doubt, recompress!
