[Hemodynamic profile in acute respiratory distress syndromes in the adult (author's transl)].

Hemodynamic, investigations carried out on 25 patients suffering from acute respiratory distress in the adult established a specific hemodynamic profile for that syndrome, including precapillary pulmonary artery hypertension and systemic arterial hypotension. The level of pulmonary vascular resistance (abnormally high) and systemic arterial resistance (abnormally low) were referred to the cardiac index (which may be increased in some patients due to infusions of Dopamine, or reduced in others due to an veno-arterial bypass). The observed hemodynamic disorders are not related to hypoxemia since this is corrected by permanent positive pressure breathing, or by extracorporeal oxygenation.
