1.1 Features
1.1.1 What the Instrument Can Do
„ VS-1500N
The instrument measures the non-invasive blood pressure in all four limbs to simultaneously
obtain ECG, PCG, carotid pulse tracing, femoral pulse tracing and four limb pulse tracing. This
makes it possible to examine arterial extensibility and the degree of blood circulation disorders
in blood vessels in the lower limbs of a patient.
„ VS-1500N with ECG Upgrade Package
In addition to the above, by installing the optional standard 12-lead ECG testing software (ECG
Upgrade Package: VSC-150), the 12-lead ECG examination function is enabled. This package
allows 12-lead ECG testing, to record ECG and analysis results both for screening patients with
heart disease and for general ECG testing.
1.1.2 Major Features
„ VS-1500N
● CAVI (Cardio Ankle Vascular Index)
Independent of blood pressure, the Cardio Ankle Vascular Index calculates the specific
hardness of arterial walls. As an index for early detection of arteriosclerosis diseases, CAVI
provides a means to diagnose arteriosclerosis in patients with hypertension, hyperlipemia,
diabetes, myocardial infarction and cerebral infarction. The CAVI is also useful for time-serial
observation of medication effects.
The index is compatible with the PWV method, a classical index for measuring aortic stiffness.
This instrument measures the following 4 types of CAVI.
(1) R-CAVI: CAVI between the heart valve and right ankle artery, calculated from
measurements of PCG (heart sound Ⅱ ) and plethysmograms taken using
cuffs applied to the right brachial and right ankle.
(2) L-CAVI: CAVI between the heart valve and left ankle artery, calculated from
measurements of PCG (heart sound
Ⅱ
) and plethysmograms taken using
cuffs applied to the right brachial and left ankle.
(3) R-kCAVI: CAVI between the heart valve and right popliteal artery, calculated from
measurements of PCG (heart sound Ⅱ ) and plethysmograms taken using
a cuff applied to the right brachial and a sensor applied to the right knee
joint.
(4) L-kCA
VI:
CAVI between the heart valve and left popliteal artery, calculated from
measurements of PCG (heart sound Ⅱ ) and plethysmograms taken using
a cuff applied to the right brachial and a sensor applied to the left knee
joint.
● Simultaneous Measurement of Blood Pressures of Brachial’s and Ankles
The instrument measures non-invasive blood pressures of brachial’s and ankles simultaneously.
It also allows selection of any brachial and ankle for measurement.
●
BPB (BP Balance)
BPB is a two-dimensional graphic indication of blood pressure measured at ankles and
brachial’s. It makes it easy to establish the BP balance of upper and lower limbs and helps to
indicate arterial stenosis and blockage of the lower limbs.
