The guidelines for performing ABI prescribe that the ABI index should be determined at the arm with the highest blood pressure value. For this the screen mode should be used for performing simultaneous double-arm measurements.
After the arm with the highest BP value is determined one arm cuff (at the “R” cuff socket) can be replaced for the ankle cuff and blood pressure of the ankle and arm can be simultaneously measured in the ABI mode. After the measurement is performed the ABI will be automatically calculated by the device.
The ABI mode of the WatchBP Office ABI shows a reminder for the supine position (left) and automatically calculates the ABI from systolic blood pressure values (right; 1.09 = 148/136)
