Total lung compliance is:
|A||Less than chest wall compliance|
|B||More than chest wall compliance|
|C||Equal to chest wall compliance|
|D||More than lung compliance|
|E||Equal to lung compliance|
Less than chest wall compliance
Compliance is defined as volume change per unit of pressure. Chest wall and lung compliance is 200 mil cmH2O but these both compliances (chest wall and lung) act in opposite direction reducing the total lung compliance to 100 ml/cmH2O.
