A bit of history…

The history of hyperbaric therapy is closely linked to underwater diving, which is thought to date back to 4500 years BC. It all started in Britain in 1662 when Mr. Henshaw used a pressurized sealed chamber to treat his patients’ ailments. In 1830 France in turn became the leader in hyperbaric medicine, with Fontaine, a French surgeon, designing the first mobile chamber for this purpose in 1877.

In America, the first hyperbaric chamber would be built in Ontario in 1860. From 1950-1960, it was reported to produce tremendous benefits in a variety of areas of application, including cases of carbon monoxide poisoning. Over the past fifteen years, the angiogenic properties of hyperbaric therapy have ranked among the leading high tech treatment processes.

What is Mild Hyperbaric Oxygen Therapy?

Mild Hyperbaric Oxygen Therapy (mHBOT) is a natural therapy in which a person is exposed to increased atmospheric pressure inside an inflatable chamber. The typical pressure reaches between 1.1 and 1.4 atmospheres, which can be expressed as 1-4 pounds per square inch. The increase in pressure allows more oxygen to reach the body’s cells, delivering a multitude of healing and therapeutic benefits.

Is there any possibility that the air pressure inside the chamber will go beyond the gauge limit?

The pressure should never exceed 1.3 or 1.4 ATA (depending on the model), as the release valve at the end of the chamber is specifically calibrated to this effect.

I hear a hissing sound coming from the rear two ports—is this normal?

Yes, this is normal, as the two valves are adjusted to a pressure of 1.3 or 1.4 ATA and release any excess pressure. That is the hissing sound you hear.

While decompressing, do I turn off the compressor or keep it running?

Keeping the compressor running will allow you to better control the release of pressure. Decompression should take approximately 15 minutes. Turn the handle very slowly. For example, decompressing from 1.4 to 1.3 takes about 5 min; 1.3 to 1.2 another 5 minutes; and 1.2 to 1.1 still another 5 minutes. At the end, the handle should be fully open.

How long does it take to fill a chamber using concentrated oxygen?

The chamber is not inflated using oxygen but rather using a compressor intended for this purpose. Filling takes approximately 5 minutes. Oxygen is only used to fill the chamber.

Are the chamber and concentrator user-friendly to install? Can we do it ourselves?

Yes, installation is very user-friendly. In fact, we pride ourselves on offering the safest, most user-friendly, and easiest-to-use chambers and concentrators. The chamber and all the components come with a well-documented manual, as well as phone and online technical support.

Regarding HBOT for ASD, can the patient use the chamber every day or is it necessary to take a break (say, 1-2 months) after 1 round of the protocol (say, 40 dives)?

The most-used protocol is 40 dives, and there are two ways to go about it: 1 time/day with 1.5 hrs/dive, or 2 times/day with 1 hr/dive. This is followed by a 4-week break before starting again. We suggest 40 dives/day, then 28 days off.

Does the chamber include a mattress? If I want to put a pillow and a blanket inside, what kinds of materials should I purchase? Do you have any recommendations?

There is already a special mattress inside the chamber. The best material for use inside the chamber is 100% cotton.

For the 1.4 ATA chamber, will the oxygen concentrator have enough pressure to fill the chamber with oxygen without worrying about the issue of back pressure?

The concentrator that we will send you is specially made for this purpose and has a capability of 30 psi. The chamber will be at 5.7 psi, so there is an ample margin. All the other concentrators only go up to 5 psi.

Are the two pressure gauges exactly the same? Do I need to read them differently?

Yes, there is a difference. On the outside gauge the 0 is on the left side, while on the inside gauge, it is on the right side.

How does an oxygen concentrator work?

An oxygen concentrator works much like a window air conditioning unit: it takes in air, modifies it, and delivers it in a new form. An oxygen concentrator takes in air and purifies it for use by people requiring medical oxygen as a result of low oxygen levels in their blood.

More specifically, it works by:

  1. Taking in air from its surroundings;
  2. Compressing the air, while the cooling mechanism keeps the concentrator from overheating;
  3. Removing nitrogen from the air via filter and sieve beds;
  4. Adjusting delivery settings with an electronic interface; and
  5. Delivering the purified oxygen via a nasal cannula or mask.
