Riester 131332SW Aneroid Sphygmomanometer and Cuff User Guide

Quick guide from the manual

This document provides instructions for the professional use of Riester aneroid sphygmomanometers. These devices are intended for measuring systolic and diastolic blood pressure on the upper arm or thigh of adults, children, and neonates. Measurements should only be performed by physicians or trained personnel. The device is a diagnostic aid and does not replace regular medical consultations.

Device description

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

Installation and setup

For wall-mounted models (e.g., ri-former big ben), remove the wing nut under the cuff basket to detach the wall bracket. Mark and drill holes, insert anchors, and secure the bracket. Reattach the unit by engaging the top part of the bracket with the cuff basket edge and securing the bottom with the wing nut. For mobile stand models, assemble the stand first, then screw the device onto it 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. Relax for 5 minutes before the first measurement.
• Cuff application: Place the cuff so the lower edge is 2-3 cm above the crook of the arm or 5 cm above the knee joint. Ensure the marking sign is over the artery and the white index line is within the marked range.
• Inflation: Close the valve by turning the screw clockwise. Pump to approximately 20 mmHg above the expected systolic value. Do not exceed 300 mmHg.
• Measurement: Open the deflation screw counterclockwise. The ideal deflation rate is 2-3 mmHg/s (needle moves 1-1.5 scale marks per second).
• Korotkoff phases: Use Phase V (K5) for adults and pregnant patients. Use Phase IV (K4) for children aged 3-12 years or if Korotkoff sounds are audible during deflation in pregnant patients.

Cleaning and maintenance

Manometer and bulb: Wipe with a damp cloth until clean. Never immerse in liquid.

Cuffs: Remove the bladder before cleaning. Cotton and nylon velcro covers can be wiped with a damp cloth or washed with soap and cold water. Disinfectable one-piece cuffs can be machine washed up to 60°C. Ensure all parts are completely dry before reuse.

Precision test: Remove the tube and hold the manometer vertically. If the needle rests at zero, the device is calibrated. If not, it requires recalibration by an authorized Riester dealer.
