DPA changes pulse beat into ‘pulse wave’ using

photo sensor technology to be able to magnify its

signals to get meaningful analysis of our cardio

vascular system using a patented algorithm looking

for any inconsistent pattern, warning sign or redflag

What is Pulse wave?

- Two light pads in a probe, one at the

top and one at the bottom, and the

light goes top down

- DPA is able to measure how much

blood has been pumped out and

circulated from how much light has

been absorbed by hemoglobin (HbO2)

- And then, the amount of light that has been absorbed

fluctuates depending on persons and situation, forming pulse

wave

How it works?

Mechanisms of Pulse wave

Interpretation of PTG

PTG (Plethysmogram): is directly obtained from the small artery of a finger-tip; shows the change of arterial blood volume

Crucial information about our cardio vascular health

- Ejection time : whether it is in the normal range, and

if not how much ‘off’

- Elasticity : How elastic or soft is the tested blood

vessel from aorta to middle arteries to peripheral

blood system

- Overall status : heart beat strength, aortic elasticity,

arterial functionality, aging index

- Studies show that there exists very close correlation

between pulse wave and arterial stiffness

- Basic info like blood pressure, pulse height and etc is

also provided

What does this tell us?

DPA provides us with critical information

DPA Clinical Applications

Accurately measures the elasticity

of small and large arteries, and

provides health care practitioners

with critical information regarding

arterial aging

The Digital Pulse wave Analyzer is

a tool used to monitor efficacy of

treatment options, lifestyle

management and the reduction of

cardiovascular risk factors

The Digital Pulse wave Analyzer is a tool that helps health care

professionals reduce cardiovascular disease in patient populations

through early detection and prevention.
