Summary: | The Maximal Inspiratory Pressure (MIP) and Maximal Expiratory Pressure
(MEP) are global measures of the maximal strength of the respiratory
muscles. Objectives: To determine the values of MIP and MEP in healthy
subjects aged 20 years old from the urban area of Manizales, Colombia
and to correlate them with sociodemographic and anthropometric
variables. Methods: This is an observational descriptive study. The
population of the study was 203.965 healthy people from Manizales, a
Colombian city located at 2150 meters above sea level. The sample size
was 308 subjects, selected using simple random sampling. The maximal
respiratory pressures were determined in the sample chosen and were
then considered according to the variables of age, gender, size,
weight, Body Mass Index (BMI), and BMI classi"cation. Finally a
predictive model was created. Results: The average MIP value among the
subjects of the study was 75±27cmH20 and the MEP value was
96.4±36cmH20. Both averages were higher in men than in women.
Predictive equations were established for the normal values of MIP and
MEP in healthy subjects; the best model for MIP was the resultant one
among age, gender and BMI classi"cation and for the MEP among gender,
weight and height. Conclusion: Maximal respiratory pressure values were
lower among the population of Manizales than those found in
international studies. Gender and anthropometric characteristics
(weight, height and BMI classi"cation) are the explanatory variables
that better support the average values of MIP and MEP in the predictive
models proposed. |
