The literature states that in order to kill viruses 100% oxygen at 2.7 ATA or above is required.However, there is no reason to believe that even mildly increased oxygen tensions may inhibit viral activity and/or make the host less hospitable to chronic viral inhabitation.
Children with autism have difficulty handling viral infections, most likely due to immune dysfunction.
It has been postulated many times that children with autism have a chronic low grade viral gastroenteritis and viral encephalitits. I speculate that one of the primary reasons HBOT works so well for so many children whose abnormal stools improve once they start HBOT is because the chronic, low-grade, smoldering live viral load harbored in the intestinal mucosa (Wakefield/Krigsman hypothesis) does poorly when surrounded by higher oxygen concentrations.
SPECT scans demonstrate the relative amount of blood that is able to reach the different areas in the brain.
Color coding allows easy visualization of what is occurring with blue areas representing little blood flow and yellow areas indicating normal blood flow.
I explain to my patients that to get cockroaches out of the kitchen, I can either kill them with my shoe or turn on the light.
