Effect of a Program of Deep Inspiration Combined to Expiratory Positive Airway Pressure in Asthmatic

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.

About this study

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.

Treatment and study plan

Deep inspiration and positive expiratory airway pressure

Other

It was used a device the combines deep inspiration and positive expiratory airway pressure in asthmatic subjects, for 5 weeks, twice a day.

Primary outcomes

  1. The effect of deep inspiration and positive expiratory airway pressure in quality of life in adults with severe asthma

    Time frame: Change in quality of life at 5 week

    The quality of life will be measure by a specific questionnaire for this population 5 weeks apart.

Secondary outcomes

  1. The effect of deep inspiration and positive expiratory airway pressure in respiratory function in adults with severe asthma.

    Time frame: Change in respiratory function at 5 week

    The respiratory function will be measure by spirometry 5 weeks apart.

  2. The effect of deep inspiration and positive expiratory airway pressure in heart rate variability in adults with severe asthma.

    Time frame: Change in heart rate variability at 5 week

    The heart rate variability will be measure by the acquisition of electrocardiogram signal 5 weeks apart.

  3. The effect of deep inspiration and positive expiratory airway pressure in exercise tolerance in adults with severe asthma.

    Time frame: Change in exercise tolerance at 5 week

    The exercise tolerance will be measure by 6 minute walk test 5 weeks apart.
