Abstract:

Introduction: The Chronic Obstructive Pulmonary Disease is a respiratory pathology, progressive, which is characterized by lesions in the lung parenchyma, leading to chronic airflow restriction. Aim: To analyze the strength of the respiratory muscles, aerobic capacity, functional capacity, quality of life, and sleep quality of patients with Chronic Obstructive Pulmonary Disease. Materials and methods: Patients (23) underwent the manovacuometry, spirometry, and six-minute walk tests, and responded to the Airway Questionnaire and Pittsburgh Sleep Quality Inventory. Results: Among the data of maximal inspiratory pressure and maximal expiratory pressure and peak oxygen volume, in both cases there was a moderate correlation (0.5319 - p=0.0075; 0.44472 - p=0.0314). Among the data on maximal inspiratory pressure and maximal expiratory pressure and the footage achieved in the walking test, in both cases there was a moderate correlation (0.5318 - p=0.0075, 0.4497 - p=0.0313). Among the quality of life and sleep quality data there was a moderate correlation (0.6). Discussion: In individuals with a diagnosis of pulmonary diseases such as COPD, several factors can be interfered by respiratory muscle strength and the complications of this disease appear to be associated. Conclusion: Low levels of respiratory muscle strength have a significant relationship with poor cardiorespiratory capacity, and that low levels of respiratory muscle strength are correlated with severe functional limitation. Quality of life has a positive relationship with sleep quality in patients under these conditions.
