■
When ABI Brachial BP Usage Method is set to "Average"
• When the difference between the right and left brachial systolic blood pressures is 10 mmHg or above :
Typical brachial blood pressure = the higher of the right or left brachial systolic blood pressure
• If the difference between the right and left brachial systolic blood pressures is 10 mmHg or below:
Typical brachial blood pressure = average of both the right and left brachial systolic blood pressure
■
When ABI Brachial BP Usage Method is set to "Highest"
Typical brachial blood pressure = the higher of the right or left brachial systolic blood pressure
The device examination results comply with the ACC/AHA and TASC II standards.
The applied standard of the output result depends on the setting.
[4] TBI (Toe Brachial Index)
The TBI (toe brachial index) is a quotient obtained by dividing the toe systolic blood pressure by the brachial systolic blood
pressure. It is effective in detecting advanced arteriosteogenesis in the ankle joints and peripheral stenosis or occlusion
beyond the ankle joint.
It is also called TBPI (toe-brachial pressure index) or TPI (toe pressure index).
R-TBI and L-TBI are obtained from the following formulas.
For details on typical brachial systolic blood pressure, refer to the section on ABI.
[5] BMI (Body Mass Index)
BMI is a measure of obesity and is obtained using the following formula.
[6] UT (Upstroke Time)
The UT is utilized as a risk marker of stenosis resulting from arteriosclerosis. Stenosis or occlusion causes the pulse wave to
rise gently leading to an increase in the UT value.
It measures the time from the rise of brachial and ankle pulse waves to the pulse wave peak.
RB-UT: UT of right brachial pulse wave LB-UT: UT of left brachial pulse wave
RA-UT: UT of right ankle pulse wave LA-UT: UT of left ankle pulse wave
