Hyperbaric Oxygen Therapy (HBOT) can boost oxygen, but how?! Oxygen is a passive diffuser inside your body. Right now, the atmosphere you’re surrounded by has a pressure and that pressure is what’s driving oxygen from the air into your lungs, and then ultimately from your lungs into circulation. Under normal atmospheric pressure, you’re already saturating red blood cells at 100%. We can’t add any higher amounts of oxygen into our system because we can only carry in our red blood cells a 100% saturation. That is, until we change atmospheric pressure. When you go into a HBOT chamber, that’s what’s happening. The HBOT chamber is creating a temporary increase in atmospheric pressure that’s surrounding the person inside the chamber. As a result, we’re creating increased pressure of the gas. And so, while at surface pressure I’m fully saturated with oxygen, As I increase atmospheric pressure inside the chamber, I’m driving more oxygen into circulation. Now, again, I said, you could only be 100% saturated in your red blood cells, So where does that extra oxygen go? It literally gets dissolved into the plasma of your blood and then ultimately into your other fluids. i.e. your interstitial fluid, lymphatic fluid, and cerebral spinal fluid. So all these other fluids inside your body ultimately are the carriers of oxygen under HBOT exposures.
