If your lung volume results fall outside of this normal range, this may suggest you have an obstructive or restrictive lung condition. ©2021 American Lung Association. Before PFT results can be reliably interpreted, three factors must be confirmed: (1) the volume-time curve reaches a plateau, and expiration lasts at least six seconds (Figure 2); (2) results of the two best efforts on the PFT are within 0.2 L of each other (Figure 3); and (3) the flow-volume loops are free of artifacts and abnormalities.5 If the patient's efforts yield flattened flow-volume loops, submaximal effort is most likely; however, central or upper airway obstruction should be considered. Spirometry is a diagnostic test that provides different measures of lung capacity. Fig. But most people don't use their entire lung capacity. Tidal volume is defined as the volume of air moved into and out of the lungs during each ventilation cycle. Similar, a female patient aged 26 with a height of 168 cm, would have the estimated VC after the formula: ((21.78 – 0.101 x Age) x Height)/1000: Vital Capacity = ((21.78 – 0.101 x 26) x 168)/1000 = 3.218 Litres.

Most lungs mature to this point between the ages of 20 and 25, but they don’t stay at that capacity forever, or even for very long. Similar to VC, functional residual capacity depends on the residual volume which is estimated through a set of formulas, more often than it is measured directly. This is the amount of air left in the lungs after exhaling as much as you can. Lung volumes measure the amount of air for a specific function, while lung capacities are the sum of two or more volumes. Lung volume is the total amount of air that you can breathe out after taking a deep breathe in.

Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation.It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume.It is approximately equal to Forced Vital Capacity (FVC). First, the doctor can do a physical exam using a stethoscope. These are the three factors accounted in the estimation: ■ Age is used as factor in the calculation as VC increases during the 20s and 30s and then follows a steady decrease towards the 50s.
