Range of Incentive Spirometers to exercise respiration through deep inhalation or exhalation, or both in one single device. The main group usually subject to pulmonary rehabilitation is patients affected by COPD (Chronicle Obstructive Pulmonary Disease), although the rehabilitation brings benefits even in patients with severe respiratory troubles or in patients with post-operative long stay in bed. The main benefits of a pulmonary rehabilitation program are to minimize the associated symptoms, the reduction of the dyspnoea and its related consequences, improving thus the quality of life of the patient by recuperating the tolerance to effort and to exercise, and a reduction of the anxiety or depression which may be associated to the disease. It is important then that patients continue the respiratory rehabilitation at home and very often the domicile is the only place where this can be performed. The devices for domicile rehabilitation must be easy to use and cost effective, but the most important aspect is that they should allow the measurement of the exercise performed. The new line of CA-MI incentive spirometers include three efficient devices for the stimulation of deep inspiration and the estimation of the improvements of the patient concerning the flow and/or the volume inspired.
