AirLife AirX Incentive Spirometer

Disposable and designed for exercising and measurement of volume flow.Pre- and postoperative patients increase lung volume by keeping theinstrument's inhalation-sensitive ball suspended with inhalation. Flowpassages vary in diameter, affecting the energy required to raise theball, which stays suspended as long as the patient maintains thiseffort. Flow indicator dial can be adjusted to indicate flow rates inml/second.
