摘要：Purpose: to evaluate if there is a correlation between the slow vital capacity and the maximum phonation time by techinique of couting numbers and if it is possible from the maximum phonation time estimate the slow vital capacity in hospitalized individuals. Methods: it is a cross-sectional study, crossover and choice of techniques (technique of numerical count and spirometry) were performed randomly (simple sortition). The slow vital capacity was measured by spirometry and maximum phonation time was assessed using the technique of counting numbers. Results: participated in the research 221 hospitalized patients. A positive correlation was observed between the Slow vital capacity and maximum phonation time evaluated on an absolute (r = 0.75; p <0.001) and relative (r = 0.76; p <0.001). From the simple linear regression of the data, were verified equations of the lines analyzed absolutely, Slow vital capacity = 55Technique of numerical count 735 (r2 = 0,56; p < 0,0001) and relative Slow vital capacity = 0,84 Technique of numerical count 14 (r2 = 0,57; p < 0,0001). Conclusions: the results obtained in this study showed a good correlation between the techniques evaluated, possible to estimate the Slow vital capacity from the techinique of couting numbers in hospitalized individuals.
