Definition : Flowmeters designed to measure the rate of gas flow that circulates through an anatomic structure (typically the airways) or the conduits of a medical device (e.g., anesthesia machine) or medical gas system. Gas flowmeters are frequently powered instruments with computerized capabilities that measure flow using electromechanical, laser, electromagnetic, ultrasonic, and/or other techniques. Gas flowmeters are used in healthcare facilities to measure oxygen, air, and/or other respiratory gas flows; instruments intended to measure and/or calibrate gas flow in medical devices (e.g., ventilators, anesthesia machines) or medical gas systems during inspection and/or calibration procedures are also available, frequently as an integral part of dedicated equipment testers (e.g., pneumatic testers). Dedicated instruments intended primarily to measure respiratory gas volume (i.e., spirometers) and flow in diagnostic tests are available.
