What is the average Residual Volume (RV) in healthy adults?
Options
- A1000 mL to 1100 mL
- B1100 mL to 1200 mL
- C1200 mL to 1300 mL
- D1300 mL to 1400 mL
Correct answer
B. 1100 mL to 1200 mL
Step-by-step solution
Residual Volume (RV): Volume of air remaining in the lungs even after a forcible expiration. This averages 1100 mL to 1200 mL.. By adding up a few respiratory volumes described above, one can derive various pulmonary capacities, which can be used in clinical diagnosis. Inspiratory Capacity (IC): Total volume of air a person can inspire after a normal expiration. This includes tidal volume and inspiratory reserve volume ( TV+IRV). Expiratory Capacity (EC): Total volume of air a person can expire after a normal inspi
