Overview
The central nervous oxygen toxicity is probably the most dramatic complication of hyperbaric medicine. Fully developed it is manifested especially by a loss of consciousness and tonic-clonic seizures of the character of the epileptic grand-mal seizures. The incidence is estimated at approximately 1 fully developed form on 10,000 expositions (for the treatment of 250 kPa, 90 min., 100% O2). Although there is no evidence that it is harmful in the long run, it is certainly an unwelcome part of hyperbaric practice. In case of loss of consciousness and seizures in an enclosed space there is an increased risk of secondary injury and the risk of non-standard situations which may bring another complications both for the patient as well as for the healthcare provider. Preventing and minimizing the risk of this phenomenon is therefore a general request for the hyperbaric practice. The aim of this paper is to compare the incidence of the central oxygen toxicity and possible prodromal stages in different treatment schemes in our department. The main difference is the inclusion of the so-called air break during treatment and thus interrupting otherwise continuous oxygen breathing. The incidence of reported adverse effects associated with the subsequent interruption of the patient's ongoing treatment was reduced.
