Explain respiratory compliance and outline the factors that affect it.
Answers were generally well structured. Better answers described lung and chest wall compliance and the pressures which are used to calculate compliance. Better answers displayed an understanding of dynamic, static and specific compliance and provided a reasonably comprehensive list of the physiological factors affecting chest and lung compliance.
Factors which affect compliance can be divided into chest wall factors and lung factors:
|Lung compliance||Chest wall compliance|
Increased lung compliance
Increased chest wall complance
Decreased static lung compliance
Decreased dynamic lung compliance
Decreased chest wall compliance
