Ankle Brachial Pressure Index (ABPI): An update for practitioners

Figures & data

Table 1 Interpretation of ABPI

Resting ABPI	Severity of disease
>1.4	Calcification may be present
>1.0	Probably no arterial disease
0.81–1.00	No significant arterial disease, or mild/insignificant disease
0.5–0.80	Moderate disease
<0.5	Severe disease
<0.3	Critical ischemia
