Respiratory Air Flow and Volume Exercise 1 : Lung volumes and capacities Exercise 2 : Pulmonary function testsCompression, Horizontal
Compromised lung volumes and capacities are often associated with restrictive lung diseases. Measures commonly used to evaluate airway function are forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and forced midexpiratory flow (FEF25%-75%). FVC is the volume of air moved...
LUNG VOLUMES AND CAPACITIES • Total lung capacity (TLC) is the amount of air the lung can contain at the height of maximum inspiratory effort. All other lung volumes are natural subdivisions of TLC. • Residual volume (RV) is the amount of air remaining within the lung after maximum ex...
Fig 6-1Depiction of lung volumes and capacities. Common measures recorded as part of spirometry investigations include: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and forced expiratory ratio (FER)%. FVC is the volume from full inspiration to forced maximal expiration...
• define and give values for the named lung volumes and capacities • explain the term dead space and how it affects alveolar ventilation • outline how FVC, FEV1 and PEFR are measured and how they change in lung disease. Measurements of lung function are of great clinical significance ...

Briefly explain the effects of exercise on pulmonary volumes and capacities. Explain what happens to the respiratory rate (breaths per minute) during exercise and what happens to the respiratory rate during the resting period after exercise.
internal intercostal muscles and abdominal muscles can be used to forcibly decrease the volume of the thoracic cavity, pushing out air Spirometer used to measure lung capacities and volumes TLC (total lung capacity) maximum volume of air in the lungs when one inhales completely ...
