Lung volumes exam review
This study material reviews lung volumes, important for understanding respiratory physiology, including the various components that make up total lung capacity and their clinical implications.

1. What is the Tidal Volume in adults?
Termini in questo set(16)
Tidal Volume (TV)
The amount of air inhaled or exhaled during normal breathing, approximately 500 mL.
Inspiratory Reserve Volume (IRV)
The maximum volume of air that can be inhaled after a normal inhalation, usually around 3000 mL.
Expiratory Reserve Volume (ERV)
The maximum volume of air that can be exhaled after a normal exhalation, roughly 1200 mL.
Residual Volume (RV)
The amount of air remaining in the lungs after maximum exhalation, about 1200 mL.
Total Lung Capacity (TLC)
The total volume of air the lungs can hold, calculated as TLC = TV + IRV + ERV + RV.
Functional Residual Capacity (FRC)
The volume of air remaining in the lungs after a normal exhalation, FRC = ERV + RV.
Vital Capacity (VC)
The maximum amount of air a person can exhale after a maximum inhalation, VC = IRV + TV + ERV.
True or false: Tidal Volume is always the same.
False, because Tidal Volume can change with physical activity.
Difference between IRV and ERV
IRV is the extra air inhaled after normal inhalation, while ERV is the extra air exhaled after normal exhalation.
Question: What does FRC stand for?
Functional Residual Capacity.
Fill in the blank: RV stands for _______.
Residual Volume.
Question: What is the average TV in adults?
About 500 mL.
True or false: TLC is the sum of all lung volumes.
True, because it includes all the lung capacities.
Which is NOT a lung volume?
Pleural Pressure, because it is not a measurable lung volume.
Question: What affects lung volumes?
Factors include age, gender, body composition, and physical fitness.
Comparison: VC vs TLC
VC is the air exhaled after max inhalation, TLC includes all lung volumes.
