Which one of the following is the correct matching of two capacities and volumes ?
Options
A.(2) 2500 mL (3) 4500 mL
B.(3) 1200 mL (4) 2500 mL
C.(4) 3500 mL (1) 1200 mL
D.(1) 4500 mL (2) 3500 mL
Solution
Inspiratory Capacity (IC) is the maximum amount of air that can be inspired after a normal expiration , IC = TV + IRV. It is 3600 mL in adult male and 2400 mL in adult female.
Residual Volume (RV) is the maximum amount of air remaining in the lungs after a forced exhalation. Its average value is 1200 mL and 1100 mL in adult male and female respectively.
