氮气是空气中含量最多的组分,经呼吸道吸入高浓度氮气会引起单纯性窒息,发病率仅次于一氧化碳与硫化氢。本文重点对氮气窒息的临床特点和急救措施,尤其是现场氧疗进行了综述,以便今后为氮气窒息的防治提供理论依据。
Nitrogen is the most abundant component of the air. Inhalation of high concentrations of nitrogen through the respiratory tract can cause asphyxiation, with the morbidity second only to that of carbon monoxide and hydrogen sulphide. This article focuses on the clinical features of nitrogen asphyxia and first aid measures, especially on-site oxygen therapy were reviewed in order to provide a theoretical basis for the prevention and treatment of nitrogen asphyxia in the future.
