Results Ninety-nine patients of 45 primary care practices with a mean ABI of 0. The mean ABI as measured in the vascular laboratory was 0.
A Bland—Altman plot demonstrated great variability between ABI measurements in primary care practice and the vascular laboratory. Both method of blood pressure measurements and method of calculating the ABI differed greatly between primary care practices.
Conclusion This study demonstrates that the ABI is often not correctly determined in primary care practice. This phenomenon seems to be due to inaccurate methods for both blood pressure measurements and calculation of the index. A guideline for determining the ABI with a hand-held Doppler, and a training programme seem necessary.
As international guidelines recommend, the reference standard for diagnosing peripheral arterial disease in primary care is measurement of the ankle brachial index ABI. The ABI is a non-invasive, simple, and inexpensive test with a good diagnostic performance if determined by well-trained professionals.
Moreover, there are various ways to perform the measurement and to calculate the index. In the situation that systolic pressures of two arms or two ankle arteries are measured, the highest, average, or lowest pressure can be used for calculating the index.
Theoretically, this results in at least 25 different possible combinations to calculate the ABI.

This study aimed to compare the reported results of ABI measurements performed in primary care with those performed in the vascular laboratory, with attention to the method used for blood pressure measurement and calculation of the index.
In addition, an inventory was made of the techniques used and ways to measure and calculate the ABI.
METHOD All consecutive patients suspected of symptomatic peripheral arterial disease, based on their complaints accompanied with an ABI measurement in primary care practice, who were referred to the researchers' outpatient vascular clinic by their GP were included in this study.
Informed consent was obtained from all patients; all referring GPs were informed about the ongoing study and informed consent was also obtained.
Methods of ABI measurement in the primary care practices were determined by a questionnaire about the resting period prior to blood pressure measurements, method of ankle and brachial systolic blood pressure measurements, numerator and denominator for calculation of the ABI, frequency of ABI assessment, and specialised training.
Questionnaires were administered after inclusion of the patients.
Standard Shipping Rules:
In all patients the ABI measurement was repeated in the vascular laboratory within a short period of time, varying between 1 and 4 weeks. Following a minute resting period, systolic blood pressures in the brachial, dorsal pedal, and posterior tibial arteries were determined in a supine position, with a hand-held pocket Doppler device Doppler MD2, 8MHz, Huntleigh Healthcare, Cardiff, UK , by a trained vascular technician blinded for the primary care ABI.
Brachial and ankle pressures were measured with 10 cm-wide sphygmomanometer cuffs, which were manually inflated and deflated. The first audible signal of the first ventricular systole was used to identify the systolic blood pressure at each location. Ankle pressures were determined with cuffs placed proximal to the malleoli. For each leg, the ABI was calculated by dividing the highest systolic ankle pressure either posterior tibial or dorsal pedal by the highest systolic pressure of both arms.Each GP referred a mean of 1.
Latent damage is not immediately obvious but can lead to the circuitry subsequently failing or becoming erratic. Active Noise Reduction ANR Active noise reduction is a technique used to reduce the amount of noise or "hiss" depending on signal level.
The probe identification detects the DC level on the output from the probe thus determining the type of probe fitted. FD2, MD2P only.
Servicing Procedures - Control Unit Due to the complexity of the product and the use of surface mount technology, the electronic circuitry is not serviceable without specialised training and equipment.
Static damage may not be immediately evident but could cause premature failure. In this mode, the Dopplex unit operates as a stop watch calibrated in BPM beats per minute.
