[Importance of measurement of systemic oxygen transport and tissue oxygenation in the treatment of acute respiratory insufficiency].

The patients with acute respiratory failure of different etiology are presented. The results of hemodynamic measurements together with those of oxygen transport and tissue oxygenation are given. The results reveal that in hypovolemic shock the transport system of oxygen and tissue oxygenation have been soon normalized by adequate therapy. However, more complicated is the condition of patients with sepsis and adult respiratory distress syndrome (ARDS) with disturbances in microcirculation. In them the oxygen uptake (VO2) is directly dependent upon the oxygen transport (DO2) i.e. much higher values of DO2 should be maintained by therapeutic measures than in conditions with intact microcirculation. According to their own experiences and data from the literature the authors consider that in patients with ARF in whom by the conventional methods the condition cannot be improved an invasive monitoring for following the hemodynamic measurements of oxygen transport and tissue oxygenation should be indicated for successful treatment.
