Medical oxygen is the only kind of oxygen, used in any real hyperbaric medicine.
Hyperbaric oxygen therapy can be performed in HARD chambers and also in so called SOFT ones. And again, HARD chambers are the only kind of chambers, used in any real hyperbaric medicine. They can generate much higher preasure and are much, much safer than SOFT (inflatable) ones.
Term, hyperbaric oxygen therapy, can only be used, when a certain combination of elevated preasure and pure 100-percent medical oxygen is in play. Everything else is nothing but a bad substitute with absolutely NO place in hyperbaric medicine. Many researches have been done world wide, regarding oxygen therapy. Allof them with pure 100-percent medical oxygen. Not a single one with oxygen concentrator.
Basic mathematical facts explains us why.
Nowadays, best oxygen concentrators produce 5-6 liters of approx. 90-percent oxygen per minute. Let us round to the maximum.
6 liters of oxygen from concentraor * 60 minutes * 90% = 324 liters of xygen per hour.
Average air consumption of a person at rest is 600 liters of air per hour. Increased under load or activity, of course. Increased environmental pressure represents exactly that. Accordingly, air consumption is increased. In case of hyperbaric oxygen therapy, oxygen consumption is increased.
During basic therapy, every patient consumes 1000 liters of pure 100-percent medical oxygen per session (60 minutes). Equivalent with increasing pressure and duration of therapy, amount of oxygen is higher.
It is more than obvious that even the best oxygen concentrator can not follow requirements of hyperbaric medicne. Adding approximately 700 liters of air to produced 320 liters of oxygen (to provide the required amount of 1000 liters per hour) shows us everything. Average percantage of oxygen during every hyperbaric therapy, using oxygen concentrators, NEVER EXCEEDS 30%. Patient can feel a little bit fresher because of that but we can not possibly talk about any real medical efficiency. Even more, long-term harmfulness due to the presence of impurities is very high.
Oxygen concentrator is a device that helps people breathe at normobaric atmosphere conditions. Patients with serious lung deseases or disabilities that can’t get enough oxygen into their bodies trough breathing air. In majority of such cases, lungs are incurable and their function is severely weakened. Patients with this kind of problems need oxygen generator so they can inhale air with much higher partial oxygen pressure. To summon things up, oxygen concentrator is a device that facilitates breathing and provides enough oxygen for people, who’s lungs are to weak to do that.
Laws of physics in hyperbaric medicine tells us more that just that. Pure oxygen (and most of other gases) dissolves at elevated pressures. It dissolves into blood plasma, spinal fluid,… and in this form much easier reaches all body tissues. Especially those with weakend or interrupted blood flow. Either due to injury or the nature of the tissue itself.
Producing oxygen with oxygen concentrator in combination with elevated air pressure has some more long-term negative consequences that we should take into consideration.
Air is a mixture of gases, mostly nitrogen and oxygen, is without color, taste and odor. It is naturally polluted by various hard particles like dust, sand, salt, lead, other heavy metals, etc.. This polution is in direct dependence on the specific area and on altitude. Naturally city air, heavily burdened with transport and industry, contains even more such impurities (allergens, lead,…).
Humidity is another factor to be considered. Whether high or low, it is allways present. If we pressurize such unfiltered air, we also linearly increase amount of impurities. At normobaric atmosphere, we all breathe them and they are not very healthy. The harmfulness of these is increasing exponentially with pressure. Therefore, it is extremely important that we use pure 100% medical oxygen in every hyperbaric treatment.
Medical oxygen is virtually free from impurities.
To achieve such purity, professional filtration systems are needed.
OXYGEN CONCENTRATORS DON’T HAVE SUCH FILTERS because they are not meant to be used under elevated pressure.
HYPERBARIC MEDICINE USES ONLY PURE, 100% MEDICAL OXYGEN.
