This is in response to the the question if anyone has ever tried a hyperbaric chamber. I have used one that pressures up to 3 ATA, or approximately 30 psi. It works very well, and I have had great success with it. I was dealing with a health issue and decided that this was the best route to go, and my condition cleared up. I am grateful to the Lord for His direction in leading me to oxygen therapy for it really works.
From my research healthy cells are aerobic & most diseases consist of anaerobic cells. This simply means that healthy cells thrive on oxygen, and the diseases, cancers, etc. thrive in a nonoxygen environment. Diseases also thrive in an acidic environment and healthy cells thrive in a balanced or alkaline environment. When you do the hyperbaric treatments, you saturate your body with pure oxygen, and most diseased conditions cannot live in that environment, so they will die off. Most professional sports team use the HBOT because they know that any athlete that is hurt, will actually heal 2 - 3 times faster while doing the treatments. The treatments for HBOT (Hyperbaric Oxygen Therapy) are very expensive ranging in price from $200 to $1500 per session. Both doctors and chiropractors use the HBOT, for there are amazing benefits to having the pressurized oxygen. As long you are careful in pressuring up and decompression, you should have no problem with the treatments. Most problems come when people pressure up to quickly and their ears can't adjust, and decompress to quickly. A good rule of thumb is when you pressure up, go at a pace that you can adjust your ears, and when you decompress, go about one pound per minute. If you are pressured up to 2 ATA or 15 psi, you will need to take about 15 min. pressuring down to be on the safe side.
If the treatments are to spendy for you, you can purchase a Hyperbaric Chamber. There are a few professional players that actually own their own chambers. You can buy Hyperbaric Chambers that are the inflatable bag kind or you could purchase one that is made out of metal. The inflatable bag ones do work, but you will not see the same benefit that you would see if your purchased or used the metal ones. The inflatable bags go up to about 5 psi and the metal ones will go up to 30 - 40 psi. Both units are spendy. You will spend $4-5000 for a bag, $20,000 to $100,000 a used metal one.
The inflatable bags ones will come with an oxygen compressor - it draws oxygen out of the air. The metal ones can be fitted with an oxygen compressor, but those are high pressure compressors and can be very expensive. You can also rent oxygen tanks for the metal ones as well. Hope this answers some questions.
