  • tidal volume

Examples of spirometry in the following topics:

  • Chronic Obstructive Pulmonary Disease (COPD)

    • The diagnosis of COPD is confirmed by spirometry, a test that measures the forced expiratory volume in one second (FEV1), which is the greatest volume of air that can be breathed out in the first second of a large breath.
    • Spirometry also measures the forced vital capacity (FVC), which is the greatest volume of air that can be breathed out in a whole, large breath.
  • Lung Volumes and Capacities

    • Lung volumes are measured by a technique called spirometry.
    • An important measurement taken during spirometry is the forced expiratory volume (FEV), which measures how much air can be forced out of the lung over a specific period, usually one second (FEV1).
  • Breathing Patterns

  • Asthma

    • Spirometry is needed to establish a diagnosis of asthma.
