Preface
This chapter provides basic information to be aware of before using the device, such as the merits of the device and the names of the parts.
Function of This Device
●
VS-2000 (Intended Use)
The device measures the non-invasive blood pressure in all four limbs to simultaneously obtain measurements such as PCG
and four limb pulse waves. This makes it possible to examine arterial extensibility and the degree of blood flow disorders in
blood vessels in the lower limbs of a patient.
The device includes a PCG and BPU-100 NIBP/Pulse Wave Unit as standard features and can measure blood pressure in all
four limbs with two channels. Another BPU-100 can be added to measure blood pressure in all four limbs with four
channels. It is also possible to measure blood pressure in the toes by connecting another BPU-100 to the IB connector.
●
BPU-100 NIBP/Pulse Wave Unit (Optional)
A unit for measuring non-invasive blood pressure and pulse wave with two channels. Adding this makes it possible to
simultaneously measure the left and right brachium and ankle blood pressure on both sides or measure blood pressure in the
toes.
●
Main Features
●
CAVI (Cardio-Ankle Vascular Index)
Independent of blood pressure, the Cardio-Ankle Vascular Index calculates the specific stiffness of arterial walls. The CAVI
is also useful for time-serial observation of medication effects.
This device measures the following 2 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 brachium 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 brachium and left ankle.
●
Four-Limb Blood Pressure
The device measures non-invasive blood pressures of brachia and ankles simultaneously. It also allows selection of any
brachium and ankle for measurement.
●
BPB (BP Balance)
The BPB is a 2D graph showing the blood pressure measured in the ankles and that measured in the brachialis muscles. It
allows the balance between the blood pressure in the upper and lower limbs to be seen at a glance, making it easy to detect
stenosis and occlusion in the limb arteries.
