Page updated 14 October 2020

The following files have been available for free download during the course of the Covid-19 pandemic with the intention of providing background information and spreading the word so to speak. Public awareness, while definitely on the increase, is still lacking to a large degree. Notwithstanding that the course of the pandemic has seen increasing support for the use of HBOT for treating Covid. The UHMS (Undersea and Hyperbaric Medical Society) as well as the EUBS (European Baromedical Society) are now in favour of compassionate use of HBOT for Covid-19 in the wake of several successful controlled trials returning 100% recovery rates.

HBOT is currently being deployed in the US, Russia, China, Japan and many more however not yet in the UK for some reason known only to the Minister of Health and the Prime Minister himself. The intention was also to help in what way we were able to by providing proprietary information for free when it was needed most. This information related to safety, hyperbaric oxygenation, physics, physiology, legislation, fire safety, gas handling, contra indications etc. We have enjoyed thousands of downloads from over 55 countries and many thousands more have visited the free blog regularly. It has been our pleasure to provide this considerable volume of information for free at a time of national and global need. We are eternally grateful for the support and positive attitude toward our work. With the pandemic now taking a more political route and not necessarily resembling the days of March when little was known about how to manage and treat the virus, and in light of the fact that we have yet to receive a single donation for the use of our material in units around the world, we find the need arises to make this content premium.

This is not done lightly or to rake in the cash over and over for the same thing. It is another potential route to raise the funds needed to pursue this community initiative. Think of it as a donation. On a consultancy basis this information would come at a much higher price. Years of research, study and work have gone into the material now listed as premium. The funds raised will all go into the pursuit of Hyperbaric Oxygen Therapy for Cumbria.

As a new entity that was just beginning to gain traction and momentum before lockdown, and subsequently unable to get out and fund raise actively, we have seen our efforts stall and little progress has been made to reach our goals for the community. Ventures such as this need investment. Unfortunately it seems that this is not forthcoming under the current model. People simply cannot afford to give what they currently have in the face of such uncertainty. Unfortunately though, needs must and the majority of the original material is now premium and available to subscribers for a payment / donation. The remaining documents which are not original work are still available at the bottom of the page for free.

There are still well over 50 free articles on the blog which too took a lot of hard work to put together. these will remain free and for those who don’t wish to download and donate, the free material will always be available and added to periodically. It’s important to differentiate between public campaigning and operational material. The blog drives public awareness and will always be free. The operational material is such that it can be incorporated into operations manuals saving much time and cost.

Unfortunately mainstream medicine doesn’t always know what it’s all about. Hyperbaric medicine is still not routinely taught at undergrad level and is generally only available as a post grad module. Accordingly most doctors aren’t familiar with it. This is not to challenge though, but rather hopefully the documents and files on this page can help raise awareness in both the medical fraternity and the general public.

We encourage readers to also actively seek out the references listed in some of the documents. There is a wealth of knowledge available in these.

Do come back regularly as files will be added to this resource centre as they are written and reviewed. We will also share those files we have permission to. Currently in production is a comprehensive operations and training resource manual which will also be made available for public viewing once completed. The completed modules have been added to the premium content parts of this page. If there is sufficient demand the remaining modules will be added and include physiology, practical operations and so on.

The files here are intended for use in our operation or for informational purposes only. No responsibility is assumed for the consequences of application of said documents in another active operation not under our supervision. Proper and appropriate training and site specific hazard identification and risk analysis (HIRA) is still required to manage and run a hyperbaric unit and chamber and these are not DIY documents. (This is a service we are also able to offer on request). Use them at your own express risk. The download and employment of any of the information contained herein is entirely voluntary and is deemed an express assumption of risk and liability and Cumbria Hyperbaric, its staff, associates and assigns accept no liability for any consequences whatsoever. Copyright subsists.

All payments are once off payments commensurate with the content of the document. If you wish to make a monthly or annually recurring donation this can be done from the home page or donate page.

Health and Safety Legislation and Practice

Health and safety in the workplace have long been of critical importance. Awareness of the risks which are present around us can be an elusive skill at times, and it is with this in mind we outline a health and safety overview here. Annexures to this document include: The Health and Safety at Work Regulations, The Noise at Work regulations, Compressed Air at Work Regulations, The Private and Voluntary Health Care act 2000

Health and Safety – Safe Gas Handling

The safe handling of gasses and more specifically the safe handling of oxygen and oxygen service is an important subject and hence the information in this section is a little more comprehensive than some others for a health and safety practice overview. Where external documentation can be consulted it is usually listed. Extra attention to specifics is presented here for oxygen service and safe gas handling owing to the added health and safety risks and hazards associated with the handling of oxygen specifically

International Standards and Their Respective Organisations

Established already is the long history of hyperbaric medicine. Often more commonly called diving medicine. It has its own post graduate medical speciality known as such. It is well established as having developed in the diving industry, nowadays with hyperbaric chambers being used increasingly for non-diving condition, namely Hyperbaric Oxygen Therapy or HBOT and still of course of course the original diving conditions it was indicated for.
Accordingly, over the years and decades, diving standards, terminology, and regulations have been applied to the use of barochambers, also and perhaps more commonly known as, hyperbaric or diving chambers. As barochambers (pressure chambers) become more and more useful in clinical and other commercial environments, it has become necessary for an increasing number of regulatory bodies


As with most things, some form of physics always applies. This is no different and even more so the case in hyperbaric applications. The physics involved are in fact diving physics which date back hundreds of years. The basis for the physiological processes discussed under physiology is a set of laws which relate to gasses and the behaviour of gasses under pressure. Being a diving tool essentially, now a medical tool as well, a hyperbaric chamber and its occupants and processes are subject to these laws of physics…

Chamber Layout and Design

The first hyperbaric chamber was created in 1662 by British Clergyman and physician Nathaniel Henshaw. Known for his work and belief in the medical benefit of “fresh Air”. His chamber or “Domiclium” as he called it, was driven by bellows. Modern day chambers are constructed from steel and driven by compressors. Usually air compressors provide the pressurised atmosphere inside the chamber.
Types of Chamber:
• Oxygen filled
• Air filled
• Monoplace
• Duoplace
• Multiplace
• BHA chamber categories….

Allied Support Equipment

In reality the chamber itself is the lesser of the total equipment used. Although it is the main focus and requires specialised skills to safely use, it is only one component in an integrated system that allows the hyperbaric complex to function smoothly. There is overlap between this section and other sections detailing various support and allied equipment. Operators and supervisors must have a working knowledge of the support equipment….

Electrical Safety

Part 1 – The Effects of Electricity on the Body – Background
Electricity flowing through the body has two primary effects. The disruption of bio-electrical activity and also the destruction of tissues. For shocks of more than one second duration the hazard is related to the current flow in the body. This can be calculated from Ohm’s law (equation 1). The disruption of physiological process can be calculated as follows

Contraindications and Side Effects

While maintaining the claim that HBOT is a non-invasive, do no harm therapy, there are a few contra indications as listed below. It would be foolish to pretend there are no absolute contra indications or side effects…

Pulmonary Gas Exchange – Gaseous Exchange

The lungs, as we know are organs essentially not unlike large sacks filled with lots of smaller sacks. Each lobe of the lungs contains increasingly smaller chambers and pathways, the smallest being the alveoli. The lungs are central to the respiratory system and facilitate the exchange of outwardly bound waste gas from the body and inward bound gasses such as oxygen. This is called gas exchange, or pulmonary gas exchange and is the fundamental mechanism of breathing…

prevention, the following items are prohibited from the chamber…

HBOT Fact Sheets

This fact sheet provides a general introduction to the benefits of Hyperbaric Oxygen Therapy (HBOT) and is aimed at people who are interested in finding out more detail about this remarkable treatment. Considering how few people know about the benefits of HBOT (even among the medical community) this fact sheet should be of interest…

HBOT Type 2 Diabetes and Obesity – A Proposal by: Hayden Dunstan

To diabetics, the subject of obesity and insulin resistance is of great importance and relevance. The inability to lose weight despite substantive efforts to follow low carbohydrate diets, and fairly active lifestyles, comes as a great disappointment to many millions of diabetics. This becomes a further frustration when medical staff disbelieve these diabetic sufferers who appear to “absorb” weight from the atmosphere, perpetuating a failing metabolic cycle that just seems unbreakable….
