A flow based incentive Spirometer is a device used in hospitals to give respiratory patients a visual demonstration of how much air they can inhale. While the instrument was designed for inhalation, if it is turned upside down, it can also be used for exhalation. There is a gauge to measure resistance, with the most open position providing the most resistance. Another use of the inspiron is in conjunction with mouthpiece practice. Remove the large hose at the base, replace with a four-inch rubber hose, and place a mouthpiece in the other end. The Inspiron must be upside down [the exhalation position]. Adjust the resistance so the ball can remain in the up position while buzzing several notes on the mouthpiece. Imagine that the air supporting the ball is a fountain of water--its height will vary but it should not hit the bottom between notes. The object is to play throughout the range of the instrument while keeping the ball suspended. When moving into the high range any attempt to increase pressure while decreasing the rate of air flow will cause the ball to drop. One of the most important uses of the incentive spirometer is to teach the relaxed low pressure/high flow rate concept of playing.
