State
Lung compliance measures how easily lung tissue expands under pressure change, while airway resistance measures how much the airways themselves impede airflow; both jointly determine breathing effort.
Show
Stiffened, low-compliance lung tissue requires more pressure change to achieve the same inhaled volume.
Watch for
Low compliance and high resistance are distinct problems with different causes, even though both increase breathing effort.
