They called having an oxygen toxicity attack "getting a Pete".In the decade following World War II, Lambertsen et al. made further discoveries on the effects of breathing oxygen under pressure and methods of prevention. Their work on intermittent exposures for extension of oxygen tolerance and on a model for prediction of pulmonary oxygen toxicity based on pulmonary function are key documents in the development of standard operating procedures when breathing increased pressures of oxygen. Lambertsens work showing the effect of carbon dioxide in decreasing time to onset of central nervous system symptoms has influenced work from current exposure guidelines to future breathing apparatus design.Retinopathy of prematurity was not observed before World War II, but with the availability of supplemental oxygen in the decade following, it rapidly became one of the principal causes of infant blindness in developed countries. By 1960 the use of oxygen had become identified as a risk factor and its administration restricted. The resulting fall in retinopathy of prematurity was accompanied by a rise in infant mortality and hypoxia-related complications. Since then, more sophisticated monitoring and diagnosis have established protocols for oxygen use which aim to balance between hypoxic conditions and problems of retinopathy of prematurity.Bronchopulmonary dysplasia was first described by Northway in 1967, who outlined the conditions that would lead to the diagnosis. This was later expanded by Bancalari and in 1988 by Shennan, who suggested the need for supplemental oxygen at 36 weeks could predict long-term outcomes. Nevertheless, Palta et al.
However, helium is not narcotic, and a usable mixture may be blended either by completely replacing nitrogen with helium (the resulting mix is called heliox), or by replacing part of the nitrogen with helium, producing a trimix.Pulmonary oxygen toxicity is an entirely avoidable event while diving. The limited duration and naturally intermittent nature of most diving makes this a relatively rare (and even then, reversible) complication for divers. Established guidelines enable divers to calculate when they are at risk of pulmonary toxicity. In saturation diving it can be avoided by limiting the oxygen content of gas in living areas to below 0.4 bar. Hyperbaric setting
The presence of a fever or a history of seizure is a relative contraindication to hyperbaric oxygen treatment. The schedules used for treatment of decompression illness allow for periods of breathing air rather than 100% oxygen (oxygen breaks) to reduce the chance of seizure or lung damage. The U.S. Navy uses treatment tables based on periods alternating between 100% oxygen and air. For example, USN table 6 requires 75 minutes (three periods of 20 minutes oxygen/5 minutes air) at an ambient pressure of 2.8 standard atmospheres (280 kPa), equivalent to a depth of 18 metres (60 ft). This is followed by a slow reduction in pressure to 1.9 atm (190 kPa) over 30 minutes on oxygen.
