The DPA uses infrared light sent to the fingertip and obtains pulse wave information with the light absorbing characteristics of Hemoglobin (the HbO2 of arterial blood). The medical terminology for this measurement method is Plethysmogram (PTG).
Cardiovascular disease is the #1 killer for both men & women in the United States with an estimated economic cost of over $300 billion.
The DPA provides information on arterial wall stiffness and determines the biological age of arteries in less than 3 minutes. This FDA cleared, user-friendly, non-invasive device uses a finger probe to observe the changes in pressure, blood flow, velocity and profile throughout the whole pulse wave.
Aging and disease states associated with an increase in cardiovascular events alter the physical characteristics of blood vessel walls and impair the pulsatile function of arteries.
The pulsatile flow is defined (http://www.rwc.uc.edu/koehler/biophys/3d.html) as that portion of the cardiac cycle controlled by the Autonomic Nervous System which is the part of the nervous system that does not require the brain’s involvement in order to function.
Impaired pulsatile function of arteries provides important predictive and therapeutic information beyond that provided by traditional blood pressure measurements.
Accelerated Plethysmogram (APG) Waveform – The second derivative of PTG – an excellent method to evaluate the biological age of arteries.
The DPA device measures a pulse waveform produced by the beating heart. Data captured by the DPA during a client test is analyzed and reported in just minutes to provide a clear, concise evaluation tool for health care professionals.
Arterial stiffness indices are particularly important in identifying individuals who exhibit the development of vascular disease, and enables the healthcare professional to begin appropriate treatment long before the symptoms or clinical signs appear. The DPA has many applications including:
One purpose of this screening is to prevent disease before symptoms occur. In those instances where symptoms have developed, laboratory tests results help confirm that a problem does exist. But a normal test result is just as significant as an abnormal result. A normal result does not mean that a test was unnecessary. When a result is normal, it not only helps rule out disease, but is also establishes a baseline “normal”. A person’s own result is the best baseline for monitoring any change that takes place in the future.
Almost everyone in this country knows about heart disease. They know the importance of prevention, detection, and treatment and the huge impact it has on people’s health. But they know very little about vascular disease outside the heart.
