<Terminology>
Blood Pressure
The blood pressure is the pressure of the flowing blood against the vascular wall, and it also serves as
the force to propel the blood flowing in the vessels.
• High Blood Pressure (SYS, Systolic Blood Pressure)
Systolic blood pressure refers to the maximum blood pressure appearing in an artery during systole
when the heart contracts to drive blood into the arterial system.
• Low Blood Pressure (DIA, Diastolic Blood Pressure)
Diastolic blood pressure is the minimum blood pressure appearing in an artery during diastole when
blood pressure in the artery keeps decreasing after the closure of the aortic valve.
Pulse Rate
• Pulse Rate
The frequency of arterial pulse wave detected by the cuff, which is generally comparable to heart
rate except under some special situations, such as in subjects with arrhythmia or severe occlusive
disease in artery or cardiac valve.
AVI & API
AVI & API are the new vascular index jointly researched and developed by RIKEN, AIST, and Shisei
Datum in Japan.
AVI & API are subject to the effect of age, gender, cholesterol level, blood pressure as the well as the
history of diabetes, smoking and exercise, etc.
AVI may be reduced through regular exercise.
• AVI (Arterial Velocity Pulse Index)
AVI is a new vascular index that developed jointly by Shisei Datum in Japan and RIKEN.
Himeno Ryutaro with his sub generation integration simulation team, and Gao muzhou with his
dominant organ Scale study team, are the research and development teams of RIKEN. Gao muzhou
is also a professor of Tokyo University.
Principle: AVI shows the characteriscs of the pulse waveform when the cu pressure is higher than
maximum blood pressure, and meanwhile converts them into numerical values as the indices of the
central arterial sness. The higher the value is, the higher risk of arterial sness it represents.
The upper waveforms of below graph are those of cu pressure pulse wave, and the lower ones
are the dierenated waveforms (dierenated pulse wave). The shape of the cu oscillaon
wave varies with the increase and early arrival of reected pressure waves accompanying aging
or arterial sening, presenng an enhanced pressure augmentaon in late systole followed by a
steeper pressure decrease. AVI is an index used to quantavely assess such wave changes, which is
calculated based on the rao of the valley value (Vr) to the peak value (Vf) of the me-dierenated
cu wave (AVI=(Vr/Vf)×20).

• API (Arterial Pressure Volume Index)
API is a new vascular index that developed jointly by AIST and Shisei Datum in Japan.
Principle: The more elasc the arteries are, the more drasc the arterial volume changes when
the cu pressure decreases. The blood vessel sness is converted into numerical values using
the gradient of the curve as an index. The higher the value is, the higher risk of upper-arm arterial
sness it represents. The cu pressure-artery volume curve is rstly measured by a cu with a
decreasing working pressure, then the curve is ed with an arctan funcon (A*arctan(B*X+C)+D).
Finally, API is dened as the reciprocal of coecient B (API=1/B).
CSBP (Estimated Value)& CAPP (Estimated Value)
• CSBP (Central Systolic Blood Pressure, estimated value)
It is cobtained by taking age, radial artery systolic pressure, pulse pressure, arterial velocity pulse
index, arterial pressure volume index and other parameters as independent variables.
CSBP (Esmated Value) = 0.0447*age + 0.8392*PSBP + 0.1793*PDBP + 0.2718*AVI + 0.2881*API +
2.3339
• CAPP (Central Aortic Pulse Pressure, estimated value)
It is cobtained by taking age, radial artery systolic pressure, pulse pressure, arterial velocity pulse
index, arterial pressure volume index and other parameters as independent variables.
CAPP (Esmated Value) = 0.1613*age + 0.0923*PSBP + 0.8192*PPP + 0.2024*AVI + 0.2537*API -
