Question

Identify the correct and incorrect match abount respiratory volumes and capacities and mark the correct answer :- A. Inspiratory capacity (IC) = TV + RV B. Vital capacity (V.C.) = TV + IRV + ERV C. Residual volume (R.V.) = VC – IRV D. Tidal volume (TV) = IC – IRV

Answer 1

(i)    Inspiratory Capacity (IC) = Tidal Volume + Residual Volume - INCORRECT

(ii)   Vital Capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV) - INCORRECT

(iii)  Residual Volume (RV) = Vital Capacity (VC) - inspiratory Reserve Volume (IRV) - INCORRECT

(iv) Tidal Volume (TV) = Inspiratory Capacity (IC) - Inspiratory Reserve Volume (IRV) - CORRECT

So, the correct answer is '(i) Incorrect, (ii) Correct, (iii) Incorrect, (iv) Correct'.
