To read a spirogram, look at the flow-volume loop to assess lung function. The size and shape of the loop can indicate if there are any abnormalities such as obstructive or restrictive lung diseases. Key parameters to evaluate include forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and the FEV1/FVC ratio. Patterns such as a decreased FEV1/FVC ratio suggest obstruction, while reduced FVC may indicate restriction.

FVC (forced vital capacity) measures the total amount of air that can be exhaled forcefully after taking a deep breath, while FEV1 (forced expiratory volume in 1 second) measures the amount of air that can be exhaled in the first second of the FVC test. These tests are commonly used to assess lung function.
measurement of lung function through spirometry yielding values including FEV1, FVC, FEV1/FVC ration PEF and FEF 25-75: 50, 75 aned soemtimes 85 % of predicted value
FVC measures the amount of gases expelled when a subject takes a deep breath & then forcefully exhales maximally and as rapidly as possible. FEV1 determines the amount of air expelled during the first second.
Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1) are important lung function tests that help diagnose and monitor conditions like asthma, COPD, and other respiratory diseases. They provide information on the overall lung health, ability to move air in and out of the lungs, and help determine the severity of lung diseases and track how well treatment is working. Abnormal values can indicate obstruction (low FEV1/FVC ratio) or restriction (low FVC), guiding healthcare providers in making appropriate treatment decisions.
The greatest volume of air that can be expelled when a person performs rapid, forced expiration.
Yes, the duration of inspiration or expiration can vary during forced vital capacity (FVC) and expiratory reserve volume (ERV) maneuvers. This variation is influenced by individual factors such as lung capacity, respiratory muscle strength, and airway resistance. In general, inspiration tends to take longer during FVC, while expiration tends to take longer during ERV.
