Abstract
Introduction: Obesity is increasing worldwide in major and treatments are limited according to the severity. In the evaluation of obese breathing pattern changed due to excess adipose tissue on the chest region, diaphragm and lungs is observed. The assessment of lung function is of great importance in quantifying respiratory disorders and diagnosis of pulmonary diseases. Objective: To compare different predictive equations for lung function with the values found in morbidly obese tests. Methods: Medical records of 30 morbidly obese patients of both sexes, aged 20 and 65, were checked. The values found in the MIP, MEP and PEF tests were compared with the predicted values by Harik-Hhan, Neder, Costa and Leiner. Results: The morbidly obese patients showed values of MIP and MEP (P<0,01) statistically lower than those predicted by the equations Harik, Neder and Costa. The values of PEF (P=0,75), the results showed to be equivalent to the obese group. Conclusion: The values of MIP and MEP found in the sample were lower than those predicted by different equations. However, the analysis of the PEF equation was equivalent to this population.
