For most people who have a cut, it heals on its own. But when you're dealing with a larger wound, a state of the art oxygen therapy is available to help it heal faster.

It sounds like a command for a submarine dive, and it looks like one too. But this capsule is not going anywhere. It's a hyperbaric oxygen chamber which is used to help heal severe wounds.

"Inside the chamber we increase that pressure to about two and half times that it would naturally be at sea level,” said Guthrie.

Through this monitor you can see patients getting treatment; they're hooded up breathing 100% oxygen.

"What that allows the body to do is dissolve a tremendous amount of whatever gas you breath in your blood stream and in our case, we have patients breath pure oxygen, so the term comes out hyperbaric oxygen therapy,” said Dr. Steven Guthrie, Seton Health's Medical Director.

Up to ten patients at a time can be treated. After the cabin is sealed, the pressure is increased very slowly. The body needs oxygen to heal and when patients breathe pure oxygen while the body is under pressure, oxygen is delivered in huge amounts into the blood stream.

"The biggest thing the hyperbaric does is reacquaint the body with the wound that it is carrying around and say I got to start healing that wound,” said Guthrie.

Most of the patients have wounds on their legs. John has diabetes and has an infection. Marjorie received burns on her legs after receiving radiation for skin cancer.

Most patients are here six times a week 90 minutes per treatment for up to eight weeks, and because it is a multi patient chamber, it feels much less than a treatment.

“The patients are doing this together, the communal aspect of being surrounded by people who have had the same difficult experience before and seeing themselves get better is a very positive reinforcement from the patients,” said Guthrie.

“This is like going to visit with your friends and sitting and watching TV and so on. We are one big happy family,” said Marjorie Leibert.

Though it takes time, the healing has begun.

"You start to feel revitalized. I am not saying you jump up and down but you can tell is something working,” said John Johnson.
