Scientists develop new capability to measure tissue oxygen
A group of scientists have developed a unique technique to measure tissue oxygen during hyperbaric oxygen treatment.
Led by Dr Ben Williams, from the department of radiology at Dartmouth Medical School in New Hampshire, the team received GEMI grant to study electron paramagnetic resonance measurement of brain tissue pO2 and oxidative stress during hyperbaric oxygen therapy in patients who have suffered strokes.
He said that the discovery will benefit medics who can draw direct measurements of pO2 which can be used to ascertain whether therapy is being applied optimally.
"We started from scratch and had to design a totally new hyperbaric chamber. It was truly exciting to see our results bear out our hypothesis," Dr Williams told delegates at a conference in Munich.
A Pilot Study of Normobaric Oxygen Therapy in Acute Ischemic Stroke, published by the American Heart Association, found that high-flow oxygen therapy can improve the condition in select patients with acute ischemic stroke.
