Abstract

Dyspnoea is a major complaint in patients with COPD, expecially when there is an increase in the ventilatory demand with exercising. Also fatigue related to muscolar activity is a factor of activity restriction for chronic patients. In these cases the manteining or possibly improving of inspiratory performance is a well known issue. We have used a simple, single-patient exerciser (Respivol) with inspiratory improvement estimation capabilities to stimulate deep inspirations and the work of respiratory muscles. We have studied 20 consecutive ambulatorial pts affected by COPD, mean age 66.4 years. During scheduled visits pts performed a spirometry, MIP (massimal inspiratory pressure) and MEP (massimal expiratory pressure), a pulsossimetry, a six-minute walking test, an evaluation of heart rate (HR), of dyspnoea grade by Borg scale and an evaluation of quality of life (QoL) by a self administered St. George questionnaire. During the first visit we gave every patient a Respivol and we did a little training. Every patient used this device at home for six months, with a daily progressive training until achieving a 45 minutes exercise during the day. Results: after three months pts showed an increasing of vital capacity (VC), FEV1, MIP and MEP values, until reaching a plateau, stable during time. Pts reported also an improving of QoL, dispnoea and tollerance to effort. During exercise nobody showed an alteration of HR (like tachycardia, arhythmia) or a decrease of pulsossimetry values.
