Problem:

Question 1: Certain chest deformities prevent normal expansion of the chest. Explain why this makes ventilation difficult in terms of pressure and volume. Explain thoroughly.

Question 2: A male patient presents with the following respiratory volumes and capacities: TV = 500 ml, ERV = 1,200 mL, IRV = 1,100 ml. What is this patient's VC? Are these values normal? If not, are they more consistent with an obstructive or restrictive disease pattern?
Show the pedigree and your calculation.
