Dynamic Compliance - Cdyn


Formula:

Dynamic Compliance: Cdyn = (Exhaled Tidal Volume - Compressed Volume) / (PIP - PEEP).


Normals:

Normal range Dynamic Compliance 30-40 mL/cmH2O. Compliance Factor is generally 2 to 4 mL/cmH2O.


About:

Dynamic compliance represents pulmonary compliance during periods of flow. Vt: Exhaled tidal volume (mL). Compressed Volume (mL) = Compliance Factor * Plateau Pressure. PIP: Peak Inspiratory Pressure (cmH2O). PEEP: Positive End-Expiratory Pressure (cmH2O).
