What to Expect

Looking in a chamber

HBO therapy may be administered in an acrylic monoplace chamber. While in the chamber you will breathe 100% oxygen while subject to increased atmospheric pressure.

There is very little sensation while undergoing HBO therapy. During pressurization you will get a “fullness” buildup in your ears as a result of the pressure change. This feeling is similar to diving down to the bottom of a swimming pool, driving through the mountains or flying in a plane. The hyperbaric staff will show you how to relieve this fullness so thatyou can avoid discomfort during your treatment. 

Once the treatment begins, you will hear a hissing sound as the chamber pressurizes. You may also notice a temporary increase in temperature during this compression. A staff member will remain with you to adjust the rate of compression according to your tolerance and coach you on relieving the full sensation in your ears. The compression phase of the treatment generally lasts about 10-15 minutes, depending upon how effective you are in clearing your ears.

Once you are at the prescribed pressure in the chamber, your ear pressure sensation will go away. You should feel absolutely normal at this time. You may watch television, listen to music, sleep, or just rest during the remainder of the treatment, which usually lasts one – two hours. We have Netflix.  

At the end of your treatment, the pressure will gradually decrease as the chamber ascends over a period of 10-15 minutes. During this decompression you will experience a popping sensation in your ears as a result of the decreasing pressure. This popping is a normal adjustment inside your ears. 

Generally, you experience no after effects from HBO therapy. However, some patients report a crackling sensation in their ears between treatments. This may be relieved in the same manner as clearing your ears during compression. If the crackling should continue, please report this to the hyperbaric staff. Additionally, some patients report feeling light headed for a few moments following treatment, but the episode is brief and the patients are soon able to continue with their normal daily activity. As with all medical procedures and treatments, there are some side effects that could result from exposure to hyperbaric oxygen. These are rare, but they will be discussed with you in detail before you sign your “Consent for Treatment” form.


1.  A generalized constriction of blood vessels that decreases edema or swelling.

2.  Activation of the immune system to fight and kill certain bacteria.

3.  Stimulation of cells to rebuild tissues and enhance healing.

4.  Inactivation of toxic materials produced by bacteria.

5.  Rebuilding of small blood vessels, such as capillaries.

7.  Enhances stem cell release.

8.  Helps to clear infections in bones and rebuild new bone.

Hyperbaric Oxygen (HBO) Therapy is a medical application, which is useful in the treatment of selected surgical and medical problems.  HBO therapy can be used as a primary treatment modality for problems such as decompression sickness (the bends), or as an adjunctive therapy to medicines and/or surgery, such as with skin grafts and problem wounds.

HBO therapy may be administered in either a large, steel cylinder called a multiplace chamber or an acrylic monoplace chamber.  While in the chamber you will breathe 100% oxygen while subject to increased atmospheric pressure.
