[ASSESSMENT OF PULMONARY VENTILATION FUNCTION AT INTENSIVE CARE UNIT PATIENTS].
The article presents the functional characteristics of lung tissue in reanimation profile patients with different pathologies with forced ventilation and auxiliary support on the background. The aim of this study was to analyze the dynamics properties of lung tissue in intensive care unit patients with symptoms of severe violations of restrictive lung tissue being on ventilatory support. Results were subjected to analysis of acid-base status and dynamics of the main indicators of the biomechanical properties of the lung in 32 patients with severe concomitant injury (n=21), acute bilateral community-acquired pneumonia (n=7), septic shock (n=4) during the entire period of the respiratory "prosthetics "(before and after the beginning of mechanical ventilation). Using during ventilatory support of patients with initial symptoms of the syndrome of acute lung damage and reduced lung function restrictive positive end-expiratory pressure of 6-10 cm of water column when the conventional (1:2; 1:2.5 at p≤0.05) and invert (2:1 at p≤0,1) ratio inhale/exhale, relatively low tidal volume (6-8 ml/kg) allows increase the compliance of the lung tissue to 11-29%. Increased expiratory time constant has a direct correlation with the value of airway resistance was due not only to the maintenance of optimal parameters for MVV (mechanical voluntary ventilation), but regular lavage of the tracheobronchial tree, which allows to maintain patency of the lower respiratory tract. The main areas during mechanical ventilation of lungs in patients with a sharp decline in restrictive lung function (ARDS, pneumonia), regardless of the reason it was summoned, optimal value is the observance of the positive end-expiratory pressure, the ratio of inhale/exhale (depending on the degree of hypoxemia), to maintain sufficient blood oxygen saturation and partial pressure of oxygen in the blood plasma.
