Physiologically restrictive lung diseases are defined by reduced total lung capacity, vital capacity and functional residual capacity, but with preserved air flow.
These diseases cause either:
The chest wall, pleura and respiratory muscles are the components of respiratory pump.
Disorders of these structures will cause lung restriction and impair ventilatory function.
These are grouped as:
Intrinsic lung diseases:
Unknown, may be immunological reaction.
Four stages are identified:
