Question

multiple choice question
which lung capacity is calculated by adding the tidal volume (tv), inspiratory reserve volume (irv), and the expiratory reserve volume (erv)?
o inspiratory capacity (ic)
o functional residual capacity (frc)
o total lung capacity (tlc)
o vital capacity (vc)

Explanation:

• Inspiratory capacity (IC) is \(TV + IRV\).
• Functional residual capacity (FRC) is \(ERV+RV\) (residual volume).
• Total lung capacity (TLC) is \(TV + IRV+ERV + RV\).
• Vital capacity (VC) is \(TV + IRV+ERV\).

Answer:

Vital capacity (VC)
