Prolonged exposure to increased partial pressure of oxygen can result in toxic effects which become progressively more severe as the inspired partial pressure andor duration of exposure is increased. The most dramatic of these are toxic effects upon the respiratory system The Lorraine-Smith Effect and upon the central nervous system The Paul Bert Effect as well as other toxic effects upon the body including destruction of red blood cells and the neurosensory tissues of the eye. Commonly recognized forms of oxygen toxicity are illustrated.
