Total Lung Capacity (TLC)

Term: Total Lung Capacity (TLC)Definition: The maximum volume of air the lungs can hold after a full inhalation, typically measured in liters.Phonetic Pronunciation: (TOH-tul LUNG KAP-uh-see)Origin: The term "Total Lung Capacity" is derived from the English words "total," meaning complete, and "lung," referring to the respiratory organs, combined with "capacity," which comes from the Latin "capacitas," meaning capability or roominess. This term has been used in medical literature to describe the full extent of lung volume since the early 20th century.Significance in Asbestos Context: Total Lung Capacity is significant in asbestos-related cases because asbestos exposure can lead to conditions like asbestosis, which can reduce lung capacity. Measuring TLC helps in diagnosing and assessing the severity of lung diseases caused by asbestos, which is crucial for medical treatment and legal claims.Example Sentence: The pulmonologist measured the patient's Total Lung Capacity to assess the extent of lung damage caused by years of asbestos exposure.Related Terms: Vital Capacity, Residual Volume, Forced Vital Capacity, AsbestosisNotes: - TLC is often reduced in patients with asbestosis due to fibrosis. - Accurate measurement of TLC requires specialized equipment like a body plethysmograph. - TLC can be affected by factors other than asbestos, such as smoking and other lung diseases.
