Riester 131272GR Aneroid Sphygmomanometer User Guide

Quick guide from the manual

This document provides essential instructions for the professional use of Riester aneroid sphygmomanometers. These devices are intended for measuring systolic and diastolic blood pressure on healthy skin of the upper arm or thigh. Measurements should only be performed by physicians or trained personnel.

Device description

All Riester aneroid manometers share a common structure consisting of a measuring system, a cuff, and an inflation system (pump ball with non-return valve and a screw or push-button air release valve). They operate on the indirect Korotkoff method.

Installation and setup

For wall-mounted models, remove the wing nut under the cuff basket, position the wall bracket, mark and drill holes, insert anchors, and fasten the bracket. Place the unit so the top engages the cuff basket edge and the bottom fits over the protruding screw, then tighten the wing nut. For mobile stand versions, assemble the stand first, then screw the device onto the stand clockwise. Height can be adjusted via the retaining screw.

Blood pressure measurement

• Patient position: Sit comfortably, legs uncrossed, back and arm supported. The cuff center should be at the level of the right cardiac atrium. The patient should be relaxed and silent; wait 5 minutes before the first measurement.
• Cuff application: Place the cuff 2-3 cm above the elbow or 5 cm above the knee. Ensure the marking sign is over the artery and the white index line is within the marked range.
• Inflation: Close the valve. Pump the cuff to approximately 20 mmHg above the expected systolic value. Never exceed 300 mmHg.
• Measurement: Open the deflation screw counterclockwise. The ideal deflation rate is 2-3 mmHg/s.
• Korotkoff phases: Use phase V (K5) for adults and pregnant women. Use phase IV (K4) for children aged 3-12 years.

Cleaning and maintenance

Manometers and bulbs should be cleaned with a damp cloth. Never immerse the manometer in liquid. For cuffs, remove the bladder before cleaning. Nylon and cotton covers can be washed with soap and cold water. Disinfectable one-piece cuffs can be machine washed up to 60°C. Ensure all components are completely dry before reuse.

Troubleshooting and precision

To test precision, remove the tube from the manometer and hold it vertically. If the needle rests at zero, the device is correctly adjusted. If the needle is outside the zero mark, the device must be recalibrated by an authorized Riester dealer.
