Reference equations are used to predict normal values for maximal respiratory pressures. Objectives: To develop predictive equations for maximal respiratory pressure in children. Methods: A total of 144 healthy children, aged between 7 and 11 years, were assessed. Maximal inspiratory and expiratory pressures were assessed with a digital manovacuometer on top of residual volume and total lung capacity, respectively. Results: The variables sex, age and weight showed association with maximal inspiratory pressure, while maximal expiratory pressure, in addition to the aforementioned variables, also showed association with height. After regression analysis, only sex and age had an influence on the variability of inspiratory and expiratory pressures. Conclusions: The present study provides reference values and proposes two equation models that predict maximal respiratory pressure values among children aged between 7 and 11 years.
