Static Compliance Calculator

Calculates static compliance from VT, Pplat, and PEEP.

Inputs

Color mode links each input to the matching equation term and solving arithmetic.

Normal/reference: Static compliance 40–60 mL/cmH₂O. If the patient is intubated, use serial measurements to establish trend.

Clinical Significance

Static compliance estimates respiratory system compliance using plateau pressure and PEEP.

It emphasizes elastic load because plateau pressure is measured during no-flow conditions.

Valid measurement requires an inspiratory hold and minimal patient effort during the plateau pressure measurement.
