SDRA reprezintă forma cea mai severă de insuficienţă respiratorie hipoxemică. Acest sindrom se caracterizează prin inflamarea parenchimei pulmonare, conducând la perturbarea schimburilor gazoase şi o eliberare sistemică a mediatorilor proinflamatori, hipoxemie, care frecvent rezultă cu insuficienţă multiplă de organe. Au fost studiate dezechilibrele metabolismului electrolitic, acido-bazic şi gazos la 174 bolnavi cu SDRA, care au fost împărţiţi în 3 loturi: leziuni pulmonare uşoare, moderate şi severe.

The acute respiratory distress syndrome (ARDS) represents the most severe form of hypoxemic respiratory failure. It is characterized by inflammation of the lung parenchyma leading to impaired gas exchange with concomitant systemic release of inflamatory mediators causing inflammation, hypoxemia and frequently resulting in multiple organ failure. The disorders of the ionic, acido-basic and gas metabolisms have been investigated in patients with ARDS. The 174 patients were divided in to 3 groups: mild, moderate and severe lung injury.
