What device is commonly used to measure lung volume in professional settings?

The spirometer is a widely used device in professional settings to measure lung volume and assess respiratory function. It works by capturing the amount of air inhaled and exhaled by the lungs, providing valuable data on lung capacity and flow rates. This information is essential for diagnosing and monitoring various pulmonary conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders.

In a clinical or occupational health context, understanding lung volume helps to evaluate how well the lungs are functioning and whether there are any restrictions or obstructions in airflow. The spirometer can also facilitate the interpretation of results in conjunction with other tests to provide a comprehensive assessment of an individual's respiratory health.

Other devices listed serve different purposes: the anthropometer measures bodily dimensions; the tensiometer measures tension or pressure in materials; and the thermometer measures temperature. These devices do not provide data related to lung function or volume, highlighting the unique role of the spirometer in respiratory diagnostics.
