Abstract

Objective: The objective of the pilot study is to obtain normal maximal inspiratory and expiratory pressures for individuals in the age group 20-70 years in the Mangalore population and to predict normal values according to age, sex, height, and weight using the regression equation. Materials and Methods: Two hundred and fifty subjects were selected through a convenient method of sampling. Fifty subjects each were enrolled in the following age groups: 20 to 29, 30 to 39, 40 to 49, 50 to 59, and 60 to 70. Each group had 50 subjects (males-25 and females-25). Baseline data such as height, weight, body mass index were recorded. Maximal inspiratory pressure (PI) and expiratory pressure (PE) were determined following standardized protocol. Result: With regard to PI max and PE max, the measured values were significantly lower than those recorded in previous studies for both males (30%) and females (20%). We found that age served as the best factor for the prediction of PI max and PE max in both genders. Conclusion: The results of this study can be used to predict respiratory muscle strength in healthy adult subjects, and the strategy employed in this study will serve as a useful, simple, reproducible, rapid assessment of respiratory muscle function and also aid the planning of treatment.
