[The general characteristics of emergency states in pulmonology]

The causes of emergency conditions may be located extrapectorally, extrapulmonarily, tracheobronchially and bronchopulmonarily as well as intrapleurally. Circulatory disorders develop due to hypoxia, hypercapnia, acidosis, blood loss. The first stage (prodromal, latent) may be marked by a hazard of sudden deterioration of the general condition of the patient; intensive therapy is necessary during the second stage, reanimation measures and surgical intervention during the third stage.
