[Characteristics of the functioning of the oxygen supply system on the 1st day following trauma in patients with various courses of the post-traumatic period].

A correlation between a number of oxygen balance parameters and the application of regression analysis methods has been studied in 67 patients within the first 24 h after trauma. The regression equations demonstrate that O2 transport (TO2) reserve sufficient to meet high metabolic requirements in the first 24 h after trauma promoted prompt normalization of the vital body functions and a more favourable course of the posttraumatic period. The formula has been derived and a nomogram has been plotted for the calculation of TO2 reserve in the first 24 h after trauma. It has been found that, with TO2 reserve less than 50 ml/(min.m2), the likelihood of complications in the posttraumatic period and the lethal outcome, especially in patients with acute respiratory failure is increased. TO2 less than 360 ml/(min.m2) is unable to ensure high O2 consumption and is prognostically unfavourable in patients with severe mechanical trauma.
