The price  for quality used DPA’s range between 4 and 8 thousand dollars. The age  and appearance of the machine are important parts of the pricing.  Another factor is the price we pay for the machine.

Depending  on the way the DPA/HRV technician is going to use the machine, there may be capabilities which do not matter to a user such as a broken internal printer (technician always uses the DPA with a computer). The metal  stand mounts may be broken which only means that the tilting of the  machine to make it easier to read the data on the screen is not done.   If the DPA is always in computer mode, the DPA screen is not referred to for information. These two capabilities do not change the performance  of the DPA however they do reduce the price.

The  Meridian software which runs on an external computer has two modes. The  DPA mode relates to the condition of the cardiovascular system. The  Heart Rate Variability (HRV) mode is a separate five minute test that  provides data on the autonomic nervous system. See a sample test being  run in the DPA mode. The results of a HRV run are also shown below.   Both modes allow you to print a standard report in color on an external  printer. You can export the information gathered from either or both  tests to excel and create a customized report.

We have  developed customized spreadsheets that make the operators explanations  easier by summarizing the technical information gathered. This is  accomplished by exporting data from the Meridian software running on an  external computer to an excel spreadsheet and transferring that  information into a spreadsheet formatted to meet your requirements. We  provide the templates and support to you as part of your purchase of a  DPA. We have templates for both the DPA and the HRV mode.

The DPA software runs on a Windows XP computer. It will run on other Windows  operating systems however may stop in the middle of a test requiring  that the computer be rebooted.  This does not occur when using the  Windows XP Operating System. Call for another solution.

For information about an article published in the May 2010 Townsend Letter entitled “Breakthrough in Clinical Cardiology: In-Office Assessment with Pulse Wave Velocity (PWV) and Digital Pulse Analysis (DPA)”. CLICK HERE

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).

Our belief is that the use of the DPA can help caregivers reduce cardiovascular disease in their client populations through early detection and prevention, and ultimately assist to decrease the associated financial costs placed on the health care industry. 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.

A Powerful New Tool for Health Care Professionals

As a health care professional using the DPA, you have a powerful new tool and advanced technology providing you with cardiovascular parameters specific to the health of arteries. In minutes, an easy-to-understand printout is available for identifying cardiovascular disease risk in your clients.

This non-invasive system is capable of measuring arterial compliance. The DPA's sensitivity to early arterial changes builds highly detailed data for assessment in determining whether clients have potential underlying vascular disease, as well as developing an outline for the practitioner of the potential effects of client-specific risk factors.

The DPA was developed specifically for use in mobile events, clinics and trade show events and can easily and successfully become an important tool in your current client recruitment & retention process.

Advanced Technology Arrives In Your Practice

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:

• Hypertension
• Borderline Hypertension
• Hyperlipidemial
• Endothelial Function

Getting started: Simple, quick and painless for practitioner and client

Your practice already has everything you need to begin using the DPA® today, and your clients comfort and ease during the test is assured.

To begin the test, the appropriate client-specific data is collected through a series of questions. As your patient rests comfortably, an arterial finger pulse sensor is placed on the left finger. The instrument's monitor displays the waveform as it is sensed. Once data is collected and analyzed, you simply print the DPA Report.

The DPA is a portable and easy-to-use "plug and play" system that requires no additional accessories or disposable components. Enjoy the following benefits:

• Minimal capital outlay
• Low monthly payments
• Per-patient-test revenue
   

Reference Ranges

The reference ranges are based on a comparable set of values obtained from similar healthy subjects. It is possible that an abnormal value may be normal for you but they should be discussed with your physician as only they are qualified to make a determination as to the significance and/or make a diagnosis.

Prevention

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.

Early Detection is Vital

In most cases, with early detection, vascular disease can be treated effectively. The DPA test is a simple screening test that may detect these potential problems, all of which are non-invasive and painless. The beauty of the screening is that it is very simple. The tests do not produce any risk or discomfort for clients, and can be done in a matter of minutes.
