The purpose of this study is to determine the effects of a deep inspiration combined to expiratory positive airway pressure protocol on respiratory function, quality of life, exercise tolerance and heart rate variability in adults with severe asthma.
Asthma is associated with high morbidity and significant mortality. This disease has functional impact on activities of daily living (ADLs) and according to some studies in the United States and Europe, the percentage of asthmatics who have significant restrictions in their ADLs is quite significant. Asthma is characterized as a major public health problem, not only in Brazil but worldwide. Currently there are few studies reporting the effects of a domiciliary program of deep inspiration associated with positive expiratory pressure in the airways of asthmatics. This study aims to analyze the benefits of this program on lung function, quality of life and response to exercise.

The effect of deep inspiration and positive expiratory airway pressure in quality of life in adults with severe asthma
The quality of life will be measure by a specific questionnaire for this population 5 weeks apart.
Time frame: Change in quality of life at 5 week
The effect of deep inspiration and positive expiratory airway pressure in respiratory function in adults with severe asthma.
The respiratory function will be measure by spirometry 5 weeks apart.
Time frame: Change in respiratory function at 5 week
The effect of deep inspiration and positive expiratory airway pressure in heart rate variability in adults with severe asthma.
The heart rate variability will be measure by the acquisition of electrocardiogram signal 5 weeks apart.
Time frame: Change in heart rate variability at 5 week
The effect of deep inspiration and positive expiratory airway pressure in exercise tolerance in adults with severe asthma.
The exercise tolerance will be measure by 6 minute walk test 5 weeks apart.
Time frame: Change in exercise tolerance at 5 week
