Inhalation intoxication with acylating pulmonotoxicants (phosgene, perfluoroisobutylene) leads to the formation of toxic pulmonary edema, pharmacological approaches to the treatment of which are ineffective. Respiratory therapy is successfully used to treat non-toxic pulmonary edema. Data on the effectiveness of respiratory support in toxic pulmonary edema are limited. The aim of the study was to experimentally evaluate the effectiveness of protective ventilation with positive end-expiratory pressure in the early period of intoxication by products of thermal degradation of fluoroplast-4. Early initiation of protective ventilation with positive end-expiratory pressure proved to be effective for the correction of toxic pulmonary edema in rabbits in the early period of intoxication by products of thermal degradation of fluoroplast-4 with pulmonotoxic effects. Respiratory support may be an effective approach for the treatment of toxic pulmonary edema caused by intoxication with acylating pulmonotoxicants.
