The Short Answer
The air you are breathing right now is about 21 percent oxygen. Inside the chamber you breathe close to pure oxygen while the pressure around you is raised slightly above normal.
The pressure is the part that matters. At normal pressure your red blood cells are already close to full, so simply breathing more oxygen does not change much. Add pressure and oxygen starts dissolving into the fluid part of your blood — the plasma. Plasma goes where red cells sometimes struggle to reach: swollen tissue, tissue with poor circulation, tissue that has been quietly short of oxygen for months.
That is the whole mechanism. More oxygen, carried a different way, reaching places that were not getting enough of it.
What Clients Tell Us They Notice
Nobody notices all of these, and nobody notices them all at once. These are simply the things people bring up most often.
Energy through the afternoon
The afternoon crash is usually the first thing to shift. More oxygen in circulation means the brain and the muscles have more to work with.
Sleep
A lot of people mention sleeping unusually well the night after a session, and sleeping better generally once they are a few weeks in.
Clearer thinking
Fewer words stuck on the tip of the tongue. Less of the foggy feeling people tend to write off as getting older.
Recovery after surgery
People four to eight weeks out of an operation use the chamber to give healing tissue more of what it needs to do the work.
Injuries that stalled
The tendon or the joint that improved for a while and then stopped. Oxygen is often the input that was missing.
Stiffness and swelling
Swelling that will not settle is often an oxygen problem underneath. Sessions are aimed squarely at calming that down.
What A Session Actually Involves
You get in, we zip the chamber, and the pressure comes up slowly over the first five to ten minutes. Your ears need to clear the way they do on a plane — swallowing or a gentle yawn is usually enough, and someone is with you the whole time.
Once you are at pressure, that is your session. It runs 60 to 90 minutes. Where you land in that range depends on what we are working on. We cycle you between oxygen and ordinary air rather than running oxygen flat out the whole time. The switching is deliberate, and it is part of why it works.
Most people read, answer email on a laptop, watch something, or fall asleep. At the end the pressure comes back down slowly and you get on with your day.

Why It Is A Course, Not A Session
This is the part most places leave until after you have paid, so here it is up front.
One session can make you feel good. Changing the way tissue behaves takes repetition. The general recommendation is 20 to 40 sessions, five to six days a week — and the days matter as much as the number, because the effect builds on consecutive days. Four days a week is the practical floor. Miss a stretch and you give ground back.
It also does not improve in a straight line. Feeling tired in the first week is common. Most clients start noticing something inside the first five to ten sessions — usually energy or sleep. The longer-lasting changes, the ones that come from shifting how the tissue behaves rather than how you feel that afternoon, typically take twenty sessions or more.
Shorter runs do have their place — a handful of sessions around a surgery, or a single session after a hard training week or a long flight. But if you are coming in for something that has been going on for years, plan on a course.
Two Chambers, Two Locations
Chula Vista has a sit-up chamber running at 1.3 ATA. You sit upright, which most people prefer if they do not like the idea of lying flat.
Kearny Mesa has an accessible chamber running at 1.4 ATA, with a large door so you can walk in or transfer across from a chair.
Both are soft-shell chambers: an inflatable shell over an internal frame, a triple-zip seal, and oxygen delivered through a mask or nasal cannula. Same hours, same team and same phone number at either location.
What Hyperbaric Oxygen Will Not Do
Our chambers run at 1.3 and 1.4 ATA. That is mild hyperbaric pressure, and it is the right pressure for what we use it for: recovery, energy, sleep, mental clarity, inflammation, and supporting tissue that is trying to heal.
It is not the pressure used for the conditions insurance covers. Those protocols run at 2.0 ATA and deeper in hard clinical chambers, and ours do not reach it. If you have been told you need hyperbaric oxygen for one of those conditions, you need a hospital-based chamber rather than us, and we will tell you that on the phone instead of booking you in.
Using mild pressure for the goals above is an area where the research is still developing, and we are careful about how we describe it for exactly that reason. No guarantees — we do not give them. Hyperbaric oxygen therapy here is used to support recovery and general wellness. It is not a substitute for medical care and it is not appropriate for every patient.
We are cash-pay, and the pressure limitation above is the honest reason why.

Not Sure If The Chamber Is Right For You?
Ask for the free callback. We will ask what is going on, what you have already tried, and whether the chamber is a sensible next step. If it is not, we will say so.
