Frequently Asked Questions - KABPMWRWHTA Kogan

How do I use the blood pressure monitor correctly?

Sit comfortably with your back supported, feet flat on the floor. Place the wrist cuff on your bare left wrist, with the display facing you. Keep your arm at heart level. Press the start button and remain still. The monitor will automatically inflate and deflate. Your reading will appear on the screen.

What do the numbers mean on the display?

The top number is systolic pressure, the middle is diastolic pressure, and the bottom is pulse rate. The monitor may also show a color indicator (green, yellow, red) based on WHO blood pressure classification.

How often should I measure my blood pressure?

It is recommended to measure at the same time each day, e.g., morning and evening. Wait at least 30 minutes after eating, drinking caffeine, or exercising before measuring.

My reading shows an irregular heartbeat symbol. What does that mean?

The irregular heartbeat symbol indicates that an irregular heartbeat was detected during measurement. It may be a sign of arrhythmia. Consult your doctor if this appears frequently.

Can I use the monitor on my right wrist?

For consistent measurements, use the left wrist unless your doctor advises otherwise. The left arm is typically closer to the heart.

How do I clean the monitor and cuff?

Use a soft, dry cloth to clean the monitor. For the cuff, gently wipe with a damp cloth and mild soap. Do not immerse in water or use chemicals. Let it air dry.

What type of batteries does it use and how long do they last?

The monitor uses 2 AAA batteries. They typically last for about 300 measurements. Replace both batteries when the battery indicator appears.

My monitor shows an error code or does not inflate. What should I do?

Common causes: batteries low, cuff not connected properly, or movement during measurement. Check batteries, ensure cuff is snug, and remain still. If error persists, refer to the manual.

Is the blood pressure monitor accurate?

The monitor has clinical validation and meets accuracy standards (±3 mmHg for blood pressure, ±5% for pulse). For best accuracy, follow proper measurement technique.

How do I transfer or delete stored readings?

The monitor stores up to 90 readings per user. To delete all readings, press and hold the memory button for 5 seconds. Readings cannot be transferred externally from the device itself (no Bluetooth on this model).

♥ General Description

Thank you for selecting KOGAN wrist blood pressure Monitor (TMB-1014-A). The monitor features blood pressure measurement, pulse rate measurement and the result storage. The design provides you with two years of reliable service.

Reading taken by the TMB-1014-A are equivalent to those obtained by a trained observer using the cuff and stethoscope auscultation method.

This manual contains important safety and care information, and provides step by step instructions for using the product.

Read the manual thoroughly before using the product.

FEATURES:

• Systolic Blood Pressure

- Pulse Rate

• Diastolic Blood Pressure

♥ Indications for use

The KOGAN Blood Pressure Monitor is digital monitors intended for use in measuring blood pressure and heartbeat rate with wrist circumference ranging from 13.5 cm to 19.5 cm (about 5-7.7 inches).

It is intended for adult indoor use only.

♥ Measurement Principle

This product uses the Oscillometric Measuring Method to detect blood pressure. Before every measurement, the unit establishes a "zero point" equivalent to the atmospheric pressure. Then it starts inflating the cuff. Meanwhile, the unit detects pressure oscillation generated by beat-to-beat pulsatile, which is used to deter-mine the systolic pressure and diastolic pressure as well as pulse rate. The device also compares the longest and the shortest intervals of detected pulse wave to with the average value, and then calculates the standard deviation. The monitor will light up a warning symbol when the calculated standard deviation is larger than or equal to 15.

When the device was used to measure patients who have common arrhythmias such as atrial or ventricular premature beats or atrial fibrillation, the best result may occur deviation. Please consult your physician about the result.

The device is contraindicated for any female subject who may be suspected of, or is pregnant. Besides provided inaccurate readings, the affects of this device on the fetus are unknown.

After the cuff inflated long time, the patient's arm and fingers will is insufficient, anaesthesia, destending pain and ecchymosis.

Please use the device under the environment which was provided in the user manual. Otherwise, the performance and lifetime of the device will be impacted and reduced.

♥ What are systolic pressure and diastolic pressure?

When ventricles contract and pump blood out of the heart, the blood pressure reaches its maximum value in the cycle, which is called systolic pressure. When the ventricles relax, the blood pressure reaches its minimum value in the cycle, which is called diastolic pressure.

♥ What is the standard blood pressure classification?

The blood pressure classification published by World Health Organization (WHO) and International Society of Hypertension (ISH) in 1999 is as follows:

CAUTION

Only a physician can tell your normal BP range. Please contact a physician if your measuring result falls out of the range. Kindly note that only a physician could tell whether your blood pressure value has reached a dangerous point.

Blood Pressure (mm Hg)\Level	Optimal	Normal	High-normal	Mild	Moderate	Severe
SYS	<120	120-129	130-139	140-159	160-179	≥180
DIA	<80	80-84	85-89	90-99	100-109	≥110

♥ Why does my blood pressure fluctuate throughout the day?

1. Individual blood pressure varies every in one day, it also affected by the way you tie your cuff and the your measurement position, so please take the measurement at the same condition.
2. The varies of the pressure is greater if the person take medicine.
3. Waiting at least 3 minutes for another measurement.

♥ Why the blood pressure I get from the hospital is different from home?

The blood pressure is different even during 24 hour because of the weather, emotion, exercise etc, specially the "white coat" in hospital which makes the results are higher than the ones at home.

The attention need to pay when you measure your blood pressure at home:

If the cuff is tied properly.

If the cuff is too tight or too loose.

If the cuff is tied on the wrist.

If you feel anxious pressured.

You had better take deep breath 2-3 times before beginning.

Advice: adjust yourself for 4-5 minutes until you calm down.

♥ If the result is the same if measuring on the right wrist?

It is ok for both wrists, but there will be some different results for different person, so suggest you measure the same wrist every time.
