The AirLife incentive spirometer is disposable and designed for exercising and measurement of volume. Preoperative and postoperative patients increase their lung volume by keeping the instrument's inhalation-sensitive ball suspended with their inhalation. The passages vary in diameter, affecting the effort required to raise the ball. The ball stays suspended as long as the patient maintains this effort. The indicator dial can be adjusted to indicate rates in mL/second. Includes spirometer housing, detachable base plate, 12" segmented corrugated tubing with 22mm O.D. and mouthpiece.
