Background: After suffering from COVID-19, a large number of patients need respiratory rehabilitation. One of the methods of rehabilitation is inhalation with salt aerosols. Objective: Our work aimed to study the effectiveness of inhalations of a dry aerosol of salt precipitated from the mineral water of the “Teplitsa multidisciplinary sanatorium”, Transcarpathian region of Ukraine. Material and Methods: 30 male patients were examined after suffering from COVID-19. We formed two groups of patients, control and main, 15 people each. Patients in the control group received inhalation with a dry aerosol of table salt of the “Aero-M-sol”. In contrast, patients in the main group received a course of inhalations with a dry aerosol of salt precipitated from the mineral water. Results and discussion: Under the influence of the rehabilitation complex in both groups, there is a performance improvement but significant changes are observed only in patients of the main group. The indicator Forced Vital Сapacity1 increased to the greatest extent, which after rehabilitation is significantly higher than in the control group (p<0.05). As a result, the Tiffeneau index significantly increases in the main group compared to the control group, reaching normal values. The main effect is associated with a decrease in obstructive complications of the respiratory tract as a result of a decrease in inflammation. The use of iodine-bromine brines (as in our case) for inhalation in the treatment of respiratory diseases has been proven to be effective, with systemic effects in the form of decreased IgE and increased IgA in the blood serum having been noticed. Conclusions: The use of haloinhalations with MW salts in the rehabilitation of patients after suffering from COVID-19 disease significantly improves the clinical condition of convalescents.
