Inspiratory Muscle Strength Training and Incentive Spirometer on Postmenopausal Asthmatic Women

Patient had to produce a high inspiratory pressure. The ball serves as visible feedback of the inspiratory flow and indicates the obtained flow on a calibrated scale on the transparent cylinder of the spirometer. If the patient flows greater than 300 milliliters per second, the float ball in first chamber will rise. As patient flow increases to 600 milliliters per second the second ball float will rise. If the patient flow exceeds 900 milliliters per second all three will be suspended. Patient should encourage holding the balls up for a few seconds

The threshold trainer is a small plastic handheld device supplied by respironics. It includes a mouthpiece and a calibrated spring loaded valve. The valve controls a constant inspiratory pressure training load and the patient must generate the inspiratory pressure in order for the inspiratory valve to be opened and allow inhalation of air.
