Figure 1 and Introduction distinguish four pressure/volume methods; Materials and Methods describes passive mechanical ventilation and measurements of static and dynamic respiratory-system compliance. Do not silently relabel total respiratory-system values as lung-only compliance.

Because deflation need not be uniexponential, the investigators measured two expiratory time constants and used their mean in the compliance equation. This is distinguished from the wiki’s original two-compartment pressure-step calculation, which is not study data.
