Application of respiron® inversed in subjects with diseasethe chronic obstructive pulmonary(copd)

Abstract

The Chronic Obstructive Pulmonary Disease - COPD is characterized by airflow limitation, which is not totally reversible. The incentive spirometer - respiron® is used by health professionals to promote lung expansion through inspiratory flow. Currently, in clinical practice, the equipment has been applied in reverse order, with one of the purposes of promoting an improvement in expiratory muscle performance, even without scientific substantiation. The overall objective of this research was to analyze the reversed respiron® use in patients with COPD. That is about a field survey, longitudinal, with four reported cases and, like exclusion criteria, clinical signs of decompensation. The way of measuring improvement in respiratory muscle performance was by the use of manovacuometry, and the use of measuring peak expiratory flow, by the peak flow for degree of pulmonary obstruction. As this research focuses on a population with COPD, it was used as analytical tool for the improvement of quality of life - QOL, the Airways questionnaire 20 - AQ20. The analysis of the relationship between reversed respiron® and manovacuometry revealed that there was an improvement in respiratory muscle in all participants, but referred to the expiratory flow peak was identified the presence of airway obstruction in three of the four participants. Regarding the AQ20 was observed subjective improvement in the QOL of all participants. Therefore, the proposed technique showed improvement in respiratory muscleperformance, however, there was an increase of airflow obstruction and all participants reported the improvement in the QOL.
