objective: the objectives of this study were to determine reference values for sniff nasal inspiratory pressure (snip) and to propose reference equations for the population of brazil. methods: we evaluated 243 healthy individuals (111 males and 132 females), between 20 and 80 years of age, with an fvc and fev1/fvc ratio %26gt; 80% and %26gt; 85% of the predicted value, respectively. all of the subjects underwent respiratory muscle strength tests to determine mip, mep, and snip. results: we found that snip values were higher in males than in females (p %26lt; 0.05) and that snip correlated negatively with age, for males (r = -0.29; p %26lt; 0.001) and for females (r = -0.33; p %26lt; 0.0001). linear regression also revealed that age influenced the predicted snip, for males (r2 = 0.09) and females (r2 = 0.10). we obtained predicted snip values that were higher than those obtained for other populations. conclusions: we have devised predictive equations for snip to be used in adults (20-80 years of age) in brazil. these equations could help minimize diagnostic discrepancies among individuals.
