About 10 percent of the people needing chambers from me are needing it due to injuries. These are usually the people that rent hyperbaric oxygen chambers and not buy them. Once recovered from their injury there is no need to keep one unless there is a need for it.
The chambers that concentrate the most oxygen into the broken capillaries and anything that requires more oxygen to the cells to heal, the 1.3 ATA chambers work as well at the 1.4 to 1.5 ATA chambers. I don't usually recommend a 1.5 ATA chamber since I'm not trying to kill some virus or bug. 1.3 ATA is fine. I strongly recommend when trying to heal an injury to keep the body core temperature up. Using the infrared mat in the chamber helps raise the voltage of the body from the infrared heat and there is higher oxygen carrying potential when the body is heated from the mat. By keeping the body temperature cold it constricts the body more. The warmer the body the more positive feedback I have gotten from those using these who are recovering from an injury. The manufacturer gives 7 day trials to see if you like the mat also.
If trying to heal from an injury, there are many protocols to take. Many people take Niacin. This makes the body really hot. Some people take magnesium oil baths.
Take my hyperbaric chamber quiz and I will recommend a chamber and help if there are any protocols I know that can help. I also recommend cold lasers for those who have injuries. I have zero point lasers (ZPE lasers) that I can loan anyone who wants one. The manufacture gives me loaners for people to try so if anyone wants a free loaner ZPE laser, I will mail one anywhere in the lower 48 states for free and cover the shipping. All I ask is for a review.
To research these Google ZPE lasers or Zero Point Lasers.
Note: HIGHER PRESSURES (ABOVE 1.3 ATA WHERE LEGAL) MAY BE NEEDED TO REACH AREAS AND BRING OXYGEN WHERE CIRCULATION IS blocked or diminished. It is harder for lower presurizied oxygen to diffuse into severely damaged cells. There are 3 different levels of pressure in soft shell chambers that diffuse oxygen at different rates - 1.3 ATA, 1.4 ATA, and 1.5 ATA, each one is equivalent to different depths. 1.3 ATA is equivalent to 10 feet of water pressure and being 10 feet below the water.
