You have acquired a high-quality Riester precision aneroid sphygmomanometer, which has been manufactured in accordance with the ISO 81060-1: 2007 standard (DIN EN ISO 81060-1: 2013) and is subject to the strictest quality controls. The excellent quality will guarantee years of reliable measurements. Intended purpose: The aneroid sphygmomanometers from Riester are used by physicians and persons trained in auscultatory blood pressure measurement to determine the systolic and diastolic blood pressure in hum-ans (adults, children, babies and neonates). Riester aneroid sphygmomanometers are intended exclusively for blood pressure measurement on healthy skin on the upper arm or thigh. The product is normally used professionally in a medical practice or a hospital. The sphygmomanometer/aneroid manometer is intended for use as a diagnostic aid. Product description / indication: All blood pressure measuring devices / aneroid manometers distributed by company Rudolf Riester GmbH are of the same basic structure. Blood Pressure measuring devices / aneroid manometers consists of measuring system, cuff and inflation system (consisting of the pump [ball with non-return valve], and the screw valve [air lock or air drain].) All devices work according to the same measuring principle: Indirect blood pressure measurement according to the Korotkoff method.

Warnings / Contraindications:

• If there is overpressure in the cuff, you can reduce the pressure with the quick release. For units with air release valve: fully open the air release screw.
  For devices with push-button valves: Press the push-button valve completely. Use the ball to pump up the cuff up approximately 20mmHg above the expected systolic blood pressure value (= the upper value). Never inflate higher than 300mmHg.

• The cuffs are offered with latex-free and latex materials. These are indicated by corresponding symbols on the cuff.

• Pay attention to the paragraph „blood pressure measurement“ in the instructions for use, the blood pressure measurement can only done by doctors and persons trained in auscultatory blood pressure measurement.

• Observe the measurement and storage conditions in the instructions for use under „Technical data“ and the information on the label.

• Check the pointer zero position as described in „Test of precision“.

• For Germany, the Medical Devices Operator Ordinance applies. See also point „metrological control“.

• A description of where the LOT No. is located can be found in the cuff table at the end of the instructions for use.

1. Nylon-velcro cuffs, Disinfectable one piece cuff
   Our nylon-velcro cuffs, Disinfectable one piece cuff have a tufted strip on one side and hooks on the other. This ensures that the cuffs can be easily opened and closed quickly and repeatedly. On all the models (with the exception of Sanaphon), the cuffs are calibrated, i.e. provided with measurement lines. To make sure that you have chosen the right cuff size, check to see whether the white index line is in the range between the arrows after the cuff has been put on. If the index line fails to reach this range, the cuff is too small. If it is beyond the range, the cuff is too large. Precise blood pressure readings can be obtained only if the correct cuff size is used. Nylon-Velcro cuffs (Two Piece Reusable Velcro Cuff), The following cuff sizes are available for all models (except sphygmotensiophone, sanaphon and exacta), see cuff table: Disinfectable one-piece cuff (One Piece Reusable Velcro Cuff One Tube/Two Tube), The following cuff sizes are available for all models (except sphygmotensiophone,sanaphon, ri-san self-measurement and exacta), see cuff table: sanaphon and ri-san (Two Piece Reusable D-Ring Cuff Self-Mesurament): Measure your arm circumference to make sure that it lies within the range indicated on the cuff. The following sizes are available: child, adult, large adult and thigh. These sizes correspond to the circumferences given in the above table.

2. Cotton-velcro cuffs self-measurement (Two Piece Reusable Cuff sphygmotensiophone):
   Our cotton velcro cuffs have a tufted strip on one side and hooks on the other. This ensures that the cuff can be easily opened and closed quickly and repeatedly. Measure your arm circumference to make sure that it lies within the range indicated on the cuff. The following cuff sizes are available for the models listed below, see cuff table: sphygmotensiophone:

3. Cotton hook cuffs (Two Piece Reusable Hook Cuff):
   On one side of these cuffs, metal bars have been worked into the fabric covering; metal hooks have been riveted to the fabric on the other side. The metal hooks are inserted into the metal bars in the cuff fabric. Measure the circumference of your arm to make sure that it lies within the range indicated on the cuff. The following cuff sizes are available for the models listed below: R1 shock-proof, minimus II, minimus  III, big ben Round / Square (all versions) and ri-san , siehe cuff table:

4. Cotton bandage cuffs (Two Piece Reusable Bandage Cuff):
   There is a bandage strip and a hook on one side of the bandage cuff. To attach the cuff, simply insert the hook into the bandage strip. Measure the circumference of your arm to make sure that it lies within the range indicated on the cuff.

The following cuff sizes are available for the models listed below: R1 shock-proof, minimus II, minimus  III, big ben Round / Square (all versions) and ri-san®, see cuff table:

• Patient position for intended use: sit comfortably, legs not crossed, back and arm supported, center of cuff on the upper arm at the level of the right cardiac atrium; the patient should be as relaxed as possible and should refrain from talking during the measuring process; approx. 5 minutes should elapse before the first measurement is taken.
• Close the valve by turning the deflation screw clockwise (except in the case of ri-san). • Putting on the cuff: Put the cuff on in such a way that the lower edge of the cuff is approx. 2 to 3 cm above the crook of the arm (level of the right cardiac atrium) or approx. 5 cm above the knee joint. Make sure that the marking sign is placed above the artery. The white index strip should be within the marked index range.
• After putting on the cuff, inflate the cuff to approx. 20 mmHg above the expected systolic blood pressure value (= the upper value) with the aid of the ball.
• When measuring blood pressure, the position of the operator is normally in front of the patient or at the patient‘s side.
• It is recommended to use phase V of the Korotkoff sounds (K5) for auscultatory measurement in adults, to use phase IV of the Korotkoff sounds (K4) for auscultatory measurement in children aged 3 to 12 years, and to use phase V of the Korotkoff sounds (K5) for auscultatory measurement in pregnant female patients, except if the Korotkoff sounds can be heard during deflation of the cuff – if this is the case, K4 is to be used.
• Place the chest piece of the stethoscope, preferably our model antiphon, catalog no. 4177-01 – 4177-05, above the artery underneath the cuff.
• For the units intended for home use, no separate stethoscope is needed, since the chestpiece is integrated in the cuff. If a unit intended for home use is used, the membrane of the chestpiece installed in the cuff must be placed above the artery. The cuff is put on by pulling the free end of the cuff through the metal retainer and closing the cuff with the aid of the hook-and-loop fastener.

1. Nylon-velcro cuffs: Close the cuff using the Velcro hook-and-loop fastener.

2. Bandage cuffs: Fasten the bandage cuff by hooking the hook onto the bandage strap.

3. Hook cuffs: In the case of a hook cuff, the metal hook is hooked onto the small metal rods of the cuff cover.

   • To enable blood pressure measurement, open the deflation screw by turning it counterclockwise. The deflation rate should ideally range between 2 and 3 mmHg/s and can be set by delicate adjustment of the screw. Visual check of the deflation rate: The needle must move through 1 to 1.5 scale marks per second on the scale. After completion of the measurement, open the valve completely for rapid deflation of the cuff.

   • The ri-san model is equipped with a push-button valve. Activate this valve in such a way that the ideal deflation rate between 2 and 3 mmHg/s is achieved. To completely deflate the cuff, press the button all the way to the stop position.

   • When the upper blood pressure value (systole) has been reached, rhythmic beats can be heard.
     Systole = The upper blood pressure value is the value that results when the heart contracts and the blood is pressed into the blood vessels.

   • When the lower blood pressure value (diastole) has been reached, the beats fall silent.
     Diastole = The lower blood pressure value that prevails when the heart muscle has expanded and is once again filling up with blood.

   • The blood pressure measurement has been completed.

   • We would like to point out to you that a unit intended for home use does not replace regular visits to the doctor and that only the doctor can accurately analyze your measured values.
