Influência da espirometria de incentivos na função pulmonar de idosos saudáveis

Abstract

Introduction: during the aging process, the person goes through physiological changes, mainly the progressive and slow decline of lung function. Objective: to investigate the influence of incentive spirometry on lung function in healthy elderly people. Methodology: a randomized clinical trial consisting of 48 elderly people, aged between 60 and 84 years old, randomly divided into a Respiron® group and a Voldyne® group. The variables evaluated were maximal expiratory pressure and maximal inspiratory pressure, forced vital capacity, expiratory volume in one second, tidal volume, minute volume, respiratory frequency and thoraco-abdominal cirtometry. After daily training for a period of 12 consecutive days subjects were reassessed. Results: there was a significant difference between pre-and post-intervention in all the variables investigated in the two groups, except for the FR. There was no significant difference between the groups. Conclusion: both flow incentive spirometer (Respiron®) and the volume incentive spirometer (Voldyne®) were effective for improving lung function of individuals in the healthy aging process.
