Avaliação da mecânica cardiorrespiratória e capacidade funcional em portadores da síndrome de down

Abstract

The objective of this paper is to evaluate the respiratory mechanics and functional capacity in patients with down syndrome (ds). Subjects with sd were selected according to the inclusion and exclusion criteria, they were accompanied by the educational service center specialized rotary club in caruaru city state of pernambuco, evaluation of peak expiratory flow (pef), manometer and 6-minute walk test (6mwt) were performed. The data were tabulated in epidata analyses program and used in statistical tools of t student, anova and pearson correlation. P ≤ 0.05 was considered statistically significant. 10 individuals with ds aged between 9 to 43 years (3 children, 1 adolescent, 6 adults) of both sexes were evaluated. There is significant reduction (p = 0.05) of the predicted values obtained in relation to pef, the obtained mip (-34.67 ± 16.5) and expected (-143.65 ± 26.0), and obtained pemax (37.50 ± 9.30) and expected (157.82 ± 32.36). The pef revealed severe obstruction airway in eight individuals. There was a moderate positive correlation (56.73%) between the mip and pef obtained. In the 6mwt there was a physiological behavior of the heart rate, blood pressure and oxygen saturation, and reduction of 50% in the distance expected. Thereby, individuals with ds present airway obstruction, deficit of inspiratory and expiratory muscle strength and lower functional capacity.
