AirLife AirX Incentive Spirometer

This spirometer is disposable and designed to exercise the lungs and measure volume flow. Whether you're in pre- or postoperative status, you can increase your lung volume by keeping the instrument's inhalation-sensitive ball suspended while inhaling. This spirometer's flow passages vary in diameter, affecting the energy required to raise the ball, which stays suspended as long as you maintain this effort. The flow indicator dial can be adjusted to indicate flow rates in mL/second.
