Preliminary remarks
Your boso ABI-system 100 is an innovation on the market of blood pressure measurement technology for medical professionals. It provides a simple way of deter-mining the ankle-brachial index (ABI) and optional pulse wave velocity (PWV). The  pressure variations (oscillations) caused by pulse waves and transmitted by the cuffs are stored and evaluated by microprocessors. The great advantage of this type of measurement is that there is no need for a microphone or amplifier which must be positioned exactly if accurate results are to be obtained. This system complies with the European directives on which the German Medical Devices Act (CE mark: CE0124) is based and with European Standard EN 1060, Part 1: “Non-invasive sphygmomanometers – General requirements” and Part 3: “Supplementary requirements for electro-mechanical blood pressure measuring systems”. Calibration checks – every 2 years at the latest – can be performed either by the manufacturer, or the trade measurement authorities, or persons who fulfil the requirements of the legislation governing the operation of medical devices (German Medical Devices Operator Ordinance section 6). Instructions for calibration checks can be found on page 14 of these user instructions. Medical electrical apparatuses are subject to specific precautions as regards electro-magnetic compatibility and must therefore be installed and operated according to the EMC instructions given on page 15.

Important information

• The same exclusion criteria apply for oscillometric ABI measurements as for Doppler measurements.
• Cardiac arrhythmias can interfere with the accuracy of a measurement and produce incorrect readings. Interference can also occur in wearers of pacemakers if they have a weak pulse. The blood pressure monitor will have no effect on the pacemaker, however.
• The device is suitable for patients of all ages, whose upper arm circumferences are between 22 and 48 cm and ankle circumferences are between 18 and 38 cm.
• The device is not suitable for newborn babies.
• Do not use the apparatus in patients with severe heart failure.
• Do not use the apparatus unattended in unconscious, helpless or unresponsive persons.
• Do not place the cuffs over open wounds, implanted stents or lymphoedema.
• Allow at least 2 minutes between 2 consecutive measurements.
• Make sure that the tubes are not kinked during the measurement. A congestion could lead to injuries.
• During measurement, the flow of blood must not be stopped any longer than necessary (> 2 minutes). In case of a malfunction of the device, take off the cuffs from the arms and legs.
• Too many measurements may lead to impairment of blood flow and thus to injries.
• The cuff should not be applied on wounds, as this may cause further injuries.
• Make sure the cuff is not applied to an arm or leg which arteries or veins are or have been under medical treatment (e.g. shunt).
• Women with mastectomy should not have a cuff on the arm at the side where the breast has been amputated.
• During the measurement, a malfunction may occur in other medical devices that are applied simultaneously on the same arm.
• Operating the device in the vicinity of strong electromagnetic fields (e.g. radiation devices, mobile phones) can cause it to malfunction (see page 15).
• The computer used for the analysis must meet the requirements of EN 60601-1.
• If the instrument is to be sold, ensure that these user instructions are enclosed.
• The instrument has to be installed in a way that the plug of the power supply is easily accessible.

Ankle-Brachial Index (ABI)

To determine the ABI value, the systolic blood pressure values of the arms and legs must be measured. Blood pressure measurement values are given in mmHg (mm of mercury).
The ABI is calculated as a quotient of the systolic pressure of the leg measurement
(the mean pressure of the posterior and anterior tibial arteries) and the higher systolic pressure of the arm measurements.

Pulse wave velocity (PWV) (optional)
The pulse wave velocity is calculated using the pulse transit time between upper arm and ankle, and body size. The measured values are given in m / s (meters per second).

Turning the device on

The main connection socket is located at the rear of the device.
Use only the boso power supply unit (order no. 410-7-154), as it produces a rectified output of the correct polarity. Other commercially available power supply units can cause damage to the electronic components, which will invalidate the warranty.
To establish the potential equalization connect an appropriate wire to the relevant potential compensation of the unit. Furthermore, the requirements of EN 60601- 1:2006 applies for potential compensation.

WARNING
The bonding conductor shall not be used as a protective conductor connection.

Installation and operation of the software of the ABI-system 100 see user instruction/installation guide of boso profil-manager XD
Preparing for an ABI / PWV (optional) measurement

WARNING
The measurement must be performed with the patient supine to ensure comparable blood pressure conditions in arms and legs. The legs must not be crossed.

The patient should rest for about 5 minutes before a measurement is taken.
Attaching the cuff
WARNING
The device should only be used with original boso CA04, CA03, CA02 or CL04 cuffs.

• The cuffs are colour-coded. Attach the individual cuffs to both upper arms and both ankles according to their colour coding (matching the symbols next to the air connection sockets on the apparatus).
• Attach the upper arm cuffs so that the lower edge of the cuff is about 2-3 cm above the elbow joint.
• The cuff should be positioned in such a way that the marking is over the brachial artery.

WARNING
Never place the metal ring over arteries, as this may produce an incorrect reading.

• Attach the ankle cuffs so that the lower edge of the cuff is about 1-2 cm above the ankle joint.
• The cuff should be positioned in such a way that the white marking is over the posterior tibial artery.
• Ensure that the cuff fits tightly at the ankle.

Assignment of cuffs to limbs.
Check that the cuffs are correctly assigned to the individual limbs by individual measurements of the right or left arm and right or left leg.

Taking an ABI / PWV (optional) measurement

• A measurement can be canceled at any time by clicking on the “Cancel measurement” button in the software or pressing the STOP key on the apparatus; all the cuffs deflate automatically. Alternatively, the cuffs can be removed from the limbs at any time. Select “Start new measurement” in the “Measurements” tab or press the START button on the apparatus. The ABI-system 100 starts the ABI measurement after a short calibration process (about 3 seconds).

• The apparatus has an intelligent automatic inflation system to ensure comfortable inflation to the correct cuff pressure. When the correct inflation pressure has been reached, the pump will switch off and the cuffs will deflate automatically.

At this point (if not before) the patient must keep all four limbs completely still and may not talk. (optional)

• Select “ABI + PWV measurement” in the registry “data” or press the START button on the unit. The ABI-system 100 starts the ABI measurement after a short calibration procedure (about 3 seconds). Upon completion of the ABI measurement and another break (about 10 seconds), the PWV measurement is started.
• After the measurement, the valves are opened automatically to allow rapid deflation of the cuffs. The measured values are displayed in the profilmanager XD.

Individual comments can be added for each ABI measurement via the “Remarks…” button. Templates can be defined and stored for later usage.

Saving an ABI / PWV (optional) measurement
To save an ABI measurement, select “Save measurement”.

The measurement must be repeated if the results are wrong Blood pressure is a dynamic parameter and can be influenced by various effects:

• movement before or during the measurement
• physical condition (stress, illness …)

Repeating an ABI / PWV (optional) measurement

• Allow an interval or at least 2 minutes between successive measurements.
• To repeat an ABI measurement select “ABI measurement” or “ABI + PWV measurement”.
• To measure one limb only, press the START key next to the corresponding symbol.
• When determining the ABI it is recommended to perform all measurements at the same time.
• If no further measurement is required, remove the cuffs from the limbs.

where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, a should be less than the compliance level in each frequency range.b Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcasts,s and TV broadcasts cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the boso unit is used exceeds the applicable RF compliance level above, the boso unit should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the boso ABI- system 100 (PWV).
