The article presents a clinical case of successful treatment of a patient with prolonged asthmatic status. The pathogenesis of purulent-septic and other life-threatening complications developing as a result of the above critical condition is described. The positive effect of a differentiated approach in conducting respiratory support depending on the stage of the disease is justified: at the beginning, when airway obstruction is in the foreground, and in the future, when restrictive respiratory disorders develop. When conducting respiratory support, the most reasonable methods for ensuring airway patency were selected. The necessity of neurovegetative blockade and myoplegia for the prevention of pulmonary barotrauma during respiratory support by aggressive ventilation modes and with the goal of antihypoxic protection of the brain is emphasized. During the treatment of the patient, it was confirmed that the optimal regime for obstruction of the bronchi is forced volume-cyclic ventilation of the lungs to provide the necessary minute volume of breathing, and in severe pneumonia, in the case of relief of bronchial obstruction, respiratory support is carried out in pressure control mode for better air-oxygen mixture distribution in the airways. The need for early tracheostomy and daily therapeutic fibrobronchoscopy to ensure airway patency and treat pneumonia has been confirmed.

Lead iodide was precipitated from aqueous solutions of 0.015 - 0.1 M Pb(NO3)2 and 0.03 - 0.2 M KI in the equimolar ratio using a laboratory model of a stirred continuous crystallizer at 22 °C. After reaching the steady state, the PbI2 crystal size distribution was measured sedimentometrically and the crystallization kinetics was evaluated based on the mean particle size. Both the linear crystal growth rate and the nucleation rate depend on the specific output of the crystallizer. The system crystallization constant either points to a significant effect of secondary nucleation by the mechanism of contact of the crystals with the stirrer blade, or depends on the concentrations of the components added due to the micromixing mechanism.
