   • 2000, Michael Roberts, Michael Jonathan Reiss, Grace Monger, Advanced Biology, Nelson, page 170:

     In humans, a spirometer can be used to record and measure lung volumes and oxygen consumption (illustration 1).

   • 2002, H. Nancy Holmes (editorial director), Illustrated Manual of Nursing Practice, Wolters Kluwer Health (Lippincott Williams & Wilkins), 3rd Edition, page 154,

     While all spirometers encourage slow, sustained maximal inspiration, they can be divided into two types: flow incentive and volume incentive.

   • 2005, E. Eber, M. S. Zach, “Spirometry: Volume-Time and Flow-Volume Curves”, in Jürg Hammer, Ernst Eber, editors, Paediatric Pulmonary Function Testing, Karger Publishers, page 95:

     Wet-type spirometers (such as the classical bell spirometer with a water seal) are simple and accurate but are no longer in use as they have a hygiene problem; they are distinguished from dry-type spirometers (e.g., bellows or piston spirometer).
