Question 2

Pathophysiology

Answer 2

Irritant cause’s inflammatory response
mucous removal impaired
chronic inflammation causes other substances to be releases damaging the lungs
cytokines released
leaking capillaries of protein rich fluid
increase mucous production
radial traction causes small airways to collapse trapping air and WOB
bronchoconstirction
decreases elasticity of airways
small alveoli become one large alveoli
surface area decreased impairing gas exchange
expiration is difficult due to loss of recoil
