Justification of the effectiveness of the rehabilitating effect of river cruises on people who have suffered COVID-19

Relevance. COVID-19 complications often manifest as respiratory disorders, mainly of restrictive and hyperventilation nature. Their pathogenesis varies, thus implying different approaches to rehabilitation, with search and justification of methods to stop external respiration dysfunction.

Intention – To justify the effectiveness of rehabilitation effects of river cruises for restoration of respiratory functions after viral pneumonia.

Methodology. 301 people permanently residing in the middle latitudes and in the North-West of Russia were examined. All the subjects suffered viral pneumonia (COVID-19) 1 month to 6 months before the study. In summertime, 143 people went on cruises along the rivers of central Russia, and 158 people stayed in their region out of special institutions. Anthropometric data were evaluated. The functions of external respiration were studied using a portable spirometer; hemodynamic parameters were determined by the Korotkov method and using computational techniques. To assess the current mental state, questionnaire surveys were used.

Results and Discussion. The obtained results indicate a statistically significant improvement in the functions of external respiration after a cruise, manifested as increase in the vital capacity by 17.2 % and in the forced vital capacity by 21.4 % in patients with restrictive manifestations and by 15.3 % and 14.7 %, respectively, in persons with predominantly hyperventilation syndrome. During the cruise, in patients with hyperventilation disorders, CO2 partial pressure consistent with hypocapnia increased by 22.5 %; the integral index of respiratory adaptation increased by 40.4 % and by 45.2 %, respectively, in the groups with restrictive and hyperventilation symptoms after the cruise. Results of the well-being scale of “Well-being, activity, mood” test increased by 47.2 %. At the same time, in those who stayed at home, changes in the indicators of the external respiration and the actual mental state were not statistically significant.

Conclusion. According to the results obtained, river cruises in the Central and the North-Western regions of Russia effectively help restore physiological respiration and circulation after viral pneumonia and can be used during convalescence to relieve post-Covid respiratory syndrome.
