BACKGROUND Maximum pressures developed by the respiratory muscles can indicate the health of the respiratory system, help to determine maximum respiratory flow rates, and contribute to respiratory power development. Past measurements of maximum pressures have been found to be inadequate for inclusion in some exercise models involving respiration. METHODS Maximum inspiratory and expiratory air...

BACKGROUND Aging results in a decline in the function of the respiratory muscles. Inspiratory muscle training is emerging as a possible intervention to attenuate the decline of respiratory muscles in the elderly. The aim of this study was to evaluate the efficacy of inspiratory muscle training on respiratory strength, diaphragm thickness, and diaphragmatic mobility in elderly women. METHODS T...

BACKGROUND The measurement of maximal respiratory pressure (MRP) is a procedure widely used in clinical practice to evaluate respiratory muscle strength through the maximal inspiratory pressure (P(Imax)) and maximal expiratory pressure (P(Emax)). Its clinical applications include diagnostic procedures and evaluating responses to interventions. However, there is great variability in the equipme...

BACKGROUND Studies on the behavior of respiratory muscle strength (RMS) in morbidly obese patients have found conflicting results. OBJECTIVES To evaluate RMS in morbidly obese women and to compare the results by using different predictive equations. METHOD This is a cross-sectional study that recruited 30 morbidly obese women and a control group of 30 normal-weight women. The subjects under...

BACKGROUND Assessment of maximum respiratory pressures is a common practice in intensive care because it can predict the success of weaning from ventilation. However, the reliability of measurements through an intubation catheter has not been compared with standard measurements. The aim of this study was to compare maximum respiratory pressures measured through an intubation catheter with the s...

BACKGROUND The literature emphasizes the need for studies to provide reference values and equations able to predict respiratory muscle strength of Brazilian subjects at different ages and from different regions of Brazil. OBJECTIVES To develop prediction equations for maximal respiratory pressures (MRP) of Brazilian adolescents. METHOD In total, 182 healthy adolescents (98 boys and 84 girls...

background and aim: some risk factors for obstructive sleep apnea (osa) such as upper respiratory airways abnormalities and obesity overlap with the risk factors for eustachian tube dysfunction (etd). in this study, we investigated the prevalence of etd in a population of patients with osa. methods: tubal dysfunction was determined by tympanometry and inflation-deflation test in 36 patients dia...

OBJECTIVES Cardiac surgery (CC) determines systemic and pulmonary changes that require special care. Awareness of the importance of respiratory muscle dysfunction in the development of respiratory failure motivated several studies conducted in healthy subjects to assess muscle strength. These studies were carried out by evaluating the maximal inspiratory pressure (MIP) and maximal expiratory pr...
