ABSTRACT:
Disposable air tubes having tracking information disposed thereon or disclosed. Spirometers for reading the tracking information on the disposable air tubes are also disclosed. The tracking information automatically ensures that air tubes are not re-used among different patients. The tracking information thus reduces or eliminates cross-contamination between patients and increases the accuracy of spirometry readings by reducing condensation buildup within the disposable air tubes.
