Samdog, you're wrong. That's not hyperbaric oxygen therapy. It's called a woundvac and provides a light vacuum (about 125 mmHg below ambient sea level pressure of 760 mmHg) to draw out exudate (pussy, or should I say pus-like ooze) and pull blood and interstitial fluid to the site to promote granulation tissue and angiogenesis, or the forming of new blood vessels and tissue. It's an amazing tool made by a company called KCI. Hyperbaric Oxygen Therapy (HBO or HBOT) on the other hand, is the use of oxygen at higher than atmospheric pressures [Hyper (Increased) + baric (pressure)] to treat wounds in what looks like a submarine. Patients and a nurse or attendant go inside and breathe oxygen from a hood. What's different about breathing oxygen in the chamber, as opposed to at the surface, is Dalton's Law of Partial Pressure. If I breathe 100% oxygen, that's 100%. You can't get any stronger than that... unless you increase the atmospheric pressure. In the chamber at 3 times atmospheric pressure (3 ATA or the equivalent of 66' pressure below the ocean) the Surface Equivalent Fractional Inspired Oxygen SEFIO2 becomes 300% relative to atmospheric conditions. This has several effects. These include vasoconstriction, angiogenesis, enhancement of fibroblast deposition, enhancement of neutrophil, basophil and eosinophil response and phagocytosis of bacteria, countering anaerobic alpha-toxins, as well as a oxidative killing effect on anaerobic bacteria. A crush injury or compartment syndrome is an approved indication for HBOT, but there's no crushed foot here. If it were a chonic osteomyelitis or diabetic wound, we might see this patient going to HBO treatments, but in this case the wound vac, debridement and wound care, along with antibiotics should do the trick. Oh, I'm not a doctor, but I stayed at a Holiday Inn Express last night.

i'd still do him.
i don't pick on the sick...
