Arterial UE

Calculated Fields

In the Arterial UE worksheet, the following fields are calculated automatically. These calculated values automatically update when any of the source values are changed.

 

Field

Source Values

Calculation Logic

WBI

Right and left brachial pressures,

Radial and ulnar Pressure

MAX Wrist Pressure ÷ MAX Brachial Pressure

DBI

Right and left rest brachial pressure,

Toe pressure

Digit Pressure ÷ MAX Brachial Pressure

Note: If acquiring pressures for 1st digit, 2nd digit, etc, DBIs will calculate individually for each digit using pressure acquired in that digit. The higher of the two brachial pressures will be used.
