Compliance answers the question “How easily will an elastic structure stretch?” or “What is the elastic resistance of a system?”

The following defines compliance in an equation form:

In a high compliance state, a minimal increase in pressure translates to a large increase in volume. In a low compliance state, a large increase in pressure translates to only a minimal increase in volume.

===Static Compliance===
Static compliance characterizes pulmonary compliance at the level of the alveoli when there is no active airflow, such as at the beginning or end of a breath.

The following defines static compliance in an equation form, where static compliance is the tidal volume divided by the '''''plateau''''' pressure minus the positive end expiratory pressure (PEEP).

Examples of medical conditions that primarily affect static compliance: pneumonia, pneumothorax, acute respiratory distress syndrome (ARDS), pulmonary fibrosis, pulmonary edema, pneumonectomy, and emphysema.

===Dynamic Compliance===
Dynamic compliance characterizes pulmonary compliance at the level of the alveoli during active airflow during the inspiratory and expiratory phases of a breath.

The following defines dynamic compliance in an equation form, where dynamic compliance is the tidal volume divided by the '''''peak''''' pressure minus the positive end expiratory pressure (PEEP).
