According to a recent survey it is observed that breathing oxygen may cause some harm to cells. The oxygen cylinder is a familiar sight around the beds of people with severe lung or heart disease.Oxygen supports the organs of the body when the heart can't deliver enough through the blood. But oxygen is often given inappropriately. Overall the fact to believed is that Oxygen is the 'breathe of life'.
A study by researchers at New York Medical College now confirms that oxygen may indeed by harmful. They administered oxygen to 25 healthy volunteers for 30 minutes, in the same way as it is given to hospital patients. Imaging studies showed a high level of oxidative stress - sufficient to cause toxic damage to cells. The study supports what some physicians have long suspected - oxygen therapy is not without hazard, and should be reserved for those cases where the benefit clearly outweighs the risk.
