Oxygen toxicity
1878.
what happens when you have to much oxygen The result of breathing increased partial pressures of oxygen is hyperoxia, an excess of oxygen in body tissues how does oxygen become toxic? It results rom the harmful effects of breathing molecular oxygen at increased partial pressures. Oxygen toxicity is a concern for underwater divers, those on high concentrations of supplemental oxygen (particularly premature babies), and those undergoing hyperbaric oxygen therapy. how does this toxicity affect the human lung? An inflammation that starts in the airways leading to the lungs and then spreads into the lungs (tracheobronchial tree). The symptoms appear in the upper chest region (substernal and carinal regions). were there any physicians/doctors who studied this phenomenon? Central nervous system toxicity was first described by Paul Bert.

Oxygen toxicity [SEP] History
Central nervous system toxicity was first described by Paul Bert in 1878. He showed that oxygen was toxic to insects, arachnids, myriapods, molluscs, earthworms, fungi, germinating seeds, birds, and other animals. Central nervous system toxicity may be referred to as the "Paul Bert effect". Pulmonary oxygen toxicity was first described by J. Lorrain Smith in 1899 when he noted central nervous system toxicity and discovered in experiments in mice and birds that had no effect but of oxygen was a pulmonary irritant. Pulmonary toxicity may be referred to as the "Lorrain Smith effect". The first recorded human exposure was undertaken in 1910 by Bornstein when two men breathed oxygen at for 30 minutes while he went on to 48 minutes with no symptoms.
