Reference values for lung function tests. II. Maximal respiratory pressures and voluntary ventilation.
The strength of the respiratory muscles can be evaluated from static measurements (maximal inspiratory and expiratory pressures, MIP and MEP) or inferred from dynamic maneuvers (maximal voluntary ventilation, MVV). Although these data could be suitable for a number of clinical and research applications, no previous studies have provided reference values for such tests using a healthy, randomly ...
متن کاملReference Values for Maximal Respiratory Pressures
Background: Maximal respiratory pressures are suitable for non –invasive evaluation of respiratory muscle function A variety of methods for subject selection and test procedures have been used for the determination of normal values and reference equations for maximal respiratory pressure (MRP). Materials and Methods: we analyzed a well-defined, healthy subgroup of 224 men and 211 women with a w...
متن کاملReference values for lung function tests. I. Static volumes.
Static lung volume (LV) measurements have a number of clinical and research applications; however, no previous studies have provided reference values for such tests using a healthy sample of the adult Brazilian population. With this as our main purpose, we prospectively evaluated 100 non-smoking subjects (50 males and 50 females), 20 to 80 years old, randomly selected from more than 8,000 indiv...
متن کاملNew reference values for maximal respiratory pressures in the Brazilian population.
OBJECTIVE To compare MIP and MEP determined in healthy subjects with those predicted using the equations proposed in another study, and, if necessary, to suggest new equations for MIP and MEP to be used in the Brazilian population. METHODS The study sample comprised 60 healthy males and 60 healthy females, 20-80 years of age (20 subjects per ten-year age bracket). Maximal respiratory pressure...
متن کاملThe role of reference values in interpreting lung function tests.
The paper by GARCIA-RIO et al. [1] in this issue of the European Respiratory Journal provides good reference values for an under-represented population and an opportunity to review the role of reference values in interpreting lung function tests. The interpretation of all observed data involves comparisons with one or more types of reference data. In clinical medicine, the comparisons usually i...
