Bandage Stretch, Layers & Sub-Bandage Pressure Calculator

Two layers is twice the pressure of one. Overlap technique moves sub-bandage pressure further than changing the bandage does.

Decision-support only. Compression therapy is a clinical decision: pressure must be verified on the patient with a sub-bandage pressure monitor, arterial supply assessed before any compression is applied, and the limb is neither cylindrical nor uniform, so a single circumference describes only one point on it.
