Scientists have claimed that oxygen treatment can help diabetics heal foot wounds and avoid lower limb amputation...

Every 30 seconds a person somewhere in the world loses a lower limb to amputation due to diabetic foot disease. Now, an international team has found in their study that oxygen can heal the debilitating wounds that plague people with diabetes.

In their study, the scientists have modelled the use of hyperbaric oxygen therapy (HBOT), which is the intermittent exposure of the body to pure oxygen under pressure, to heal the chronic wounds that lead to the need for amputation.

Jennifer Flegg of Queensland University of Technology, who led the team, said a small cut on the foot of a diabetic could have catastrophic effects because their wounds did not heal the same way as normal wounds.

Oxygen Therapy for Migraine Headaches

Two types of oxygen therapy may offer relief to people who suffer from disabling migraine and cluster headaches.

A review of a number of studies evaluated normobaric oxygen therapy and hyperbaric oxygen therapy in the treatment of migraines and cluster headaches. Normobaric therapy consists of patients inhaling pure oxygen at normal room pressure, and hyperbaric therapy involves patients breathing oxygen at higher pressure in a specially designed chamber.

Three studies reported a significant increase in the proportion of patients who had relief with hyperbaric oxygen compared to sham therapy. For cluster headaches, two studies found that a significantly greater proportion of patients had relief of their headaches after 15 minutes of normobaric therapy compared to sham therapy.

About 6 percent to 7 percent of men and 15 percent to 18 percent of women suffer from severe migraine headaches, and cluster headaches affect about 0.2 percent of the population.
