Static Compliance (Cstat) is used during periods without gas flow, such as during an inspiratory pause. Cstat = ΔV / Pplat – PEEP. Static Compliance = Pressure it takes to overcome the elastic resistance to ventilation.
|Corrected Tidal Volume (ΔV) in mL:|
|Pplat in cmH2O:|
|PEEP in cmH2O:|
|Static Compliance (Cstat) in mL/cmH2O
Normal Static Compliance is 50-100 mL/cm H2O
