Normal finger/brachial indices typically range from 0.8-0.9 (90% of normal values exceed 0.79). I assume you would comment on the lowest finger pressure (if wildly different from other finger pressures and if the patient complains of specific symptoms in the finger(s) with abnormally low pressures). Most PVR machines would report a "FBI" for each individual finger pressure automatically. Typically, in our lab, an upper extremity PVR study only includes fingers if the patient complains of symptoms in the fingers (or if the doctor requests it). We wouldn't typically record finger pressures for all 10 digits for every upper extremity PVR, unless the indication warrants it. Testing for Raynauds usually incorporates multiple finger pressures, but for thoracic outlet testing, you can usually get away with one finger PPG and no pressures (if the PPG waveforms change dramatically with arm position, it's positive).

Subject: Upper Segmental Indicies
For those doing upper ext arterial segmental studies, Do you report only
higher distal pressure / the highest brachial pressure for an index?
What is a normal finger index, same as toe? Thanks in advance! bl
