Q
Changes in respiratory system related to aging?
Lung elastin:
Chest wall stiffness:
Diaphragm strength
A
Lung elastin decreases –
Dec. FVC (inc. residual volume)
Inc. physio dead space
Chest wall stiffness Inc. –
DEC. chess wall compliance
slight inc. in lung compliance so overall decrease in total system compliance.
Diaphragm strength decreases–
Inc. A-a gradient. (v/q mismatch)
