All of the fowwing are result ina decreases lung compliance

a. an increase in the vital capacity of the lung

b. a trend toward increased ventilation relative to pulmonary perfusion

c. increase the work of breathing

d. a greater change in volume for a given change in transmural pressure

A low lung compliance would mean that the lungs would need a greater-than-average change in intrapleural pressure to change the volume of the lungs.
A high lung compliance would indicate that little pressure difference in intrapleural pressure is needed to change the volume of the lungs.
Persons with low lung compliance due to disease tend to take shallow breaths and breathe more frequently.
Two factors determine lung compliance: elasticity of the lung tissue and surface tensions at air water interfaces.
