What is another term for static compliance measurement in mechanical ventilation?

Static compliance is a measurement that reflects the elastic properties of the lung and chest wall when there is no airflow, typically noted during an end-expiratory phase. This measurement is important in understanding how much pressure is needed to expand the lungs and is usually calculated as the change in volume divided by the change in pressure (ΔV/ΔP).

The correct term "static effective compliance" clearly indicates that this measurement considers the static conditions of the respiratory system and incorporates factors that affect compliance during the absence of airflow, ensuring accurate representation of the lung's elastic characteristics during a full breath cycle.

The other terms mentioned refer to concepts that differ fundamentally from static compliance. Dynamic compliance, for example, is measured during airflow and reflects how the lungs behave under conditions of movement and resistance, while static effective compliance may imply the addition of effective respiratory factors, which could be misleading. Passive compliance is not a standard term in mechanical ventilation literature and could create confusion about its meaning.
