Setup: Beurer Upper Arm Blood Pressure Monitor BM 27+ User Manual

Introduction — beurer Upper Arm Blood Pressure Monitor BM 27+

The beurer Upper Arm Blood Pressure Monitor BM 27+ is a compact, user-friendly upper-arm device designed for accurate home monitoring of blood pressure and pulse for adults. It uses oscillometric measurement technology and displays systolic, diastolic and pulse values on a large, easy-to-read display with a colour-coded WHO/LED risk indicator for fast interpretation, plus an automatic cuff-fit check and arrhythmia (irregular heartbeat) detection to help users spot potential issues quickly (ideal for routine self-monitoring and sharing results with clinicians).

Key benefits and unique selling points include automatic inflation and deflation for comfortable measuring, a cuff-fit confirmation (“OK” indicator) to reduce user error, multi-user memory (4 x 30 memory spaces) for household tracking, and a clear coloured classification scale to simplify result interpretation for non-experts.

Target audiences and use cases: adults managing hypertension or cardiovascular risk, caregivers tracking relatives’ vitals at home, and consumers who want clinically meaningful home measurements to share with doctors during consultations. The BM 27+ is also suited for older users because of its large display and simple single-button operation.

Estimated price range and availability: retail pricing typically falls into the entry-to-mid-level home monitor category; expect an approximate price range of USD/GBP/EUR equivalent for a basic upper-arm monitor (commonly stocked by medical suppliers, pharmacies and online retailers). The device is widely available from official Beurer outlets and authorised resellers in many regions.

Before the Blood Pressure Measurement

General Rules When Measuring Your Own Blood Pressure

• In order to generate an informative profile of changes in your blood pressure that can be used for comparisons, you should measure your blood pressure regularly and always at the same time of day.
• Measure your blood pressure twice a day: once in the morning after getting up and once in the evening.
• Always perform the measurement when you are sufficiently physically rested. Avoid taking measurements at stressful times.
• Do not measure within 30 minutes of eating, drinking, smoking or exercising.
• Before the initial blood pressure measurement, make sure always to rest for about 5 minutes.
• If you want to take several measurements in succession, always make sure that you leave 5 minutes between each measurement.
• Repeat the measurement if you have doubts about the measured value.

Attaching the Cuff

You can measure your blood pressure on either arm. Some deviations between the values in the right and left arm are perfectly normal. Always perform the measurement on the arm with the higher blood pressure values. Consult your doctor about this before starting self-measurement.

• Always measure your blood pressure on the same arm.
• Only use the device with the cuff supplied, based on your upper arm circumference.
• Before taking the measurement, check the fit using the index mark described below.
• Expose your upper arm. The circulation of the arm must not be hindered by tight clothing or similar.
• The cuff must be placed on the upper arm so that the bottom edge is positioned 2–3 cm above the elbow and over the artery. The line should point to the centre of the palm here B.
• The cuff should be fastened so that two fingers fit under the cuff when it is closed C.
• Now insert the cuff line into the connection for the cuff connector.
• The cuff is suitable for you if the index mark is within the OK range after fitting the cuff.

Adopting the Correct Posture

• Sit in a comfortable upright position when taking the blood pressure measurement. Lean back so that your back is supported.
• Place your arm on a surface D.
• Place your feet flat on the ground next to one another.
• The cuff must be level with your heart.
• Stay as still as possible during the measurement and do not talk.

Selecting the User

• This device can have up to 4 users with 30 memory spaces each, allowing you to separately save measurements from 4 different people. If multiple people are using the device, make sure that the correct user has been selected before each measurement:
• Use M to select the desired user.

Evaluating the results

General Information About Blood Pressure

• Blood pressure is the force with which the bloodstream presses against the arterial walls. Arterial blood pressure constantly changes in the course of a cardiac cycle.
• Blood pressure is always stated in the form of two values:
  • Systolic Blood Pressure: The highest pressure is the systolic blood pressure. This occurs when the heart muscle contracts and blood is pumped into the blood vessels.
  • Diastolic Blood Pressure: The lowest pressure is the diastolic blood pressure. This occurs when the heart muscle has completely relaxed again and the heart is filling with blood.
• Fluctuations in blood pressure are normal. Even during repeat measurements, there may be considerable differences between the measured values.
• One-off or irregular measurements therefore do not provide reliable information about the actual blood pressure. Reliable assessment is only possible when you perform the measurement regularly under comparable conditions.

Cardiac Arrhythmia

• The device can identify heart rhythm abnormalities during the blood pressure measurement.
• If the arrhythmia symbol is displayed after the measurement, this indicates that an irregularity has been detected in your pulse.
• Repeat the measurement if the arrhythmia symbol is displayed.
• When assessing your blood pressure, only use the results that have been recorded without any irregularities in your pulse.
• Consult your doctor if the arrhythmia symbol is displayed frequently. Only they can determine, through an examination, whether there is an abnormality.

Risk Indicator

• The risk indicator 5 / 12 indicates which category the recorded blood pressure values fall into.

• If the measured values are in two different categories (e.g. systolic pressure in the “high normal” range and diastolic pressure in the “normal” range), the risk indicator always indicates the higher range – “high normal” in the example described.

  

Low Blood Pressure

WARNING

• Low blood pressure (hypotension) can be a health hazard and cause dizziness or fainting.
• Blood pressure is considered low if systolic and diastolic pressure are below 90/60 mmHg (source: National Health Service, 2023).
• Seek medical attention if you suddenly suffer from low blood pressure.

• If you store the device and cuff, do not place heavy objects on the device and cuff. The cuff line should not be bent sharply.
• Remove the batteries if the device is not going to be used for a long period of time.

Troubleshooting — Common problems, error codes and fixes

• No power/device won’t switch on: Replace batteries (device typically uses 4 × AAA) and ensure correct polarity; clean battery contacts if corroded.
• “Lo” or cuff error / poor reading: Ensure cuff is wrapped snugly on the upper arm (22–42 cm) at heart level; an “OK” cuff-fit indicator should appear—reposition and retake measurement after sitting quietly for 5 minutes.
• Irregular heartbeat alert: The monitor flags possible arrhythmia during measurement; repeat the reading after 5 minutes and consult a healthcare professional if irregularities persist.
• Inconsistent or implausible values: Check cuff placement, remain still and silent during measurement, avoid caffeine/exercise 30 minutes before testing, and measure the same arm (left preferred) at consistent times for accurate trends.
• Error symbols and fixes: Follow the device manual for specific symbols — common solutions are re-applying the cuff, replacing batteries, and retaking measurements. Persistent errors may indicate a fault requiring authorised service.
• Preventive measures: Store in supplied pouch, avoid dropping, keep cuff dry and clean, follow calibration/validation guidance from your clinician, and replace batteries when low to avoid corrupted measurements.
• Warranty & support: Beurer products typically include manufacturer warranty and local support; keep proof of purchase and serial number (on device/battery compartment). For technical support and warranty claims contact Beurer customer service or the authorised retailer from which you purchased the unit.
• Contact for help: Use the official Beurer support channels or the retailer’s support line listed on your purchase paperwork for repairs, spare cuffs or replacement parts.
