[Morphological changes in lung tissue developing during controlled respiration in patients with severe neurological...

Morphological analysis of lungs was carried out in patients dying in the Department of Neurology who were treated before death by controlled respiration with respirators. Changes in the pulmonary tissue included mainly atelectasis and chronic oedema. For a better analysis the material was divided into 4 groups. Group I included earliest changes with slight atelectasis and hyperaemia of alveolar septa. Group II comprised cased with advanced atelectasis and manifest oedema. Group III contained cases with hyaeline membrane presence. In group IV pulmonary fibrosis was found. These findings were similar to those observed in other patients treated with respirators.
