Lung volumes and lung capacity Lung volumes and lung capacities refer to the volume of air associated with different phases of the respiratory cycle. Lung volumes are directly measured; lung capacities are inferred from lung volumes. The average human respiratory rate is 30-60 breaths per minute at birth, decreasing to 12-20 breaths per minute in adults. The total amount of air that the lungs can accommodate is divided into four separate volumes and four capacities. Combinations of these volumes are used to designate lung capacities. Lung volume and capacity vary with age, race, height, and gender The following terms describe the various lung (respiratory) volumes: Summing specific lung volumes produces the following lung capacities: In obstructive lung disorders include asthma and other COPDs, such as emphysema and chronic bronchitis In restrictive lung disorders include pulmonary fibrosis, adult respiratory distress syndrome, and pulmonary edema. Differences between lung volume and capacity Lung volume Lung capacity It is the total volume of air in the lungs It is the maximum volume of air that can be inhaled and exhaled during forced breathing It is the sum of the vital capacity and residual volume It is the sum of tidal volume, inspiratory reserve volume and expiratory volume It varies from 5-6 liters It varies from 3.5-4.5 liters Lung volume Lung capacity It is the total volume of air in the lungs It is the maximum volume of air that can be inhaled and exhaled during forced breathing It is the sum of the vital capacity and residual volume It is the sum of tidal volume, inspiratory reserve volume and expiratory volume It varies from 5-6 liters It varies from 3.5-4.5 liters Solution Lung volumes and lung capacity Lung volumes and lung capacities refer to the volume of air associated with different phases of the respiratory cycle.

1. Lung volumes and lung capacity
Lung volumes and lung capacities refer to the volume of air associated with different phases of
the respiratory cycle. Lung volumes are directly measured; lung capacities are inferred from lung
volumes.
The average human respiratory rate is 30-60 breaths per minute at birth, decreasing to 12-20
breaths per minute in adults. The total amount of air that the lungs can accommodate is divided
into four separate volumes and four capacities. Combinations of these volumes are used to
designate lung capacities. Lung volume and capacity vary with age, race, height, and gender
The following terms describe the various lung (respiratory) volumes:
Summing specific lung volumes produces the following lung capacities:
In obstructive lung disorders include asthma and other COPDs, such as emphysema and chronic
bronchitis
In restrictive lung disorders include pulmonary fibrosis, adult respiratory distress syndrome, and
pulmonary edema.
