Alicn Medical Shenzhen AES-U393 Arm Blood Pressure Monitor Instruction Manual

Alicn Medical Shenzhen AES-U393 Arm Blood Pressure Monitor

Introduction

Thank you for purchasing the Arm Blood Pressure Monitor. The blood pressure monitor uses the oscillometric method of blood pressure measurement. This means the monitor detects your blood’s movement through your brachial artery and converts the movements into a digital reading. An oscillometric monitor does not need a stethoscope so the monitor is simple to use. The Blood Pressure Monitor comes with the following components:

• Monitor
• Arm Cuff
• 4×AAA batteries
• Instruction Manual
• Please read this instruction manual thoroughly before using the unit.
• Please keep it for future reference.
• For specific information about your own blood pressure, please consult your doctor.

Precautions for Measurement

To ensure a reliable reading follow these recommendations:

• Avoid eating, drinking alcohol, smoking, exercising, and bathing 30 minutes before taking a measurement. Rest for at least 5 minutes before taking the measurement.
• Stress raises blood pressure. Avoid taking measurements during stressful times.
• Use the same arm when repeating the measurement, and if it is your first time measuring your blood pressure, measure both of your arms.
• Remove tight-fitting clothing from your arm.
• Sit on a chair with your feet flat on the floor. Rest your arm on the table so that the cuff is at the same level as your heart.

Applying the Arm Cuff

1. Make sure the air plug is securely inserted into the main unit.
2. Remove tight-fitting or thick clothing from your upper arm. Do not wear any accessories, please bare your upper arm or wear a thin shirt for measurement.
3. Apply the cuff to your left upper arm.
4. Do not wrap the cuff too tight, the bottom of the cuff should be about 2-3cm above your elbow.
5. After wrapping the cuff, put the air tube on the inside of your arm and make it aligned with the middle finger.
6. If it’s not convenient to measure with your left arm, please measure with your right arm follow the instructions as below.

Correct Measurement Posture

1. Correct posture: sit on a chair as shown in the figure below with your feet flat on the floor. Place your arm on the table so the cuff is level with your heart. Relax for the measurement.
2. Keep quiet during the measurement. Do not shake, talk or eat to avoid inaccuracy.
3. Since blood pressure can vary from time to time throughout the day, please take measurements at the same time every day to ensure reliability.

Taking A Measurement

1. 1. Press the START/STOP button, and the monitor will reset to zero and start the measurement, it detects the pulse rate during inflation, please do not move until the entire measurement process is completed.
2. As the cuff deflates, decreasing numbers appear on the display, and the Heartbeat Symbol ( ) flashes at the same time. When the measurement is complete, the arm cuff deflates automatically, and the blood pressure and pulse rate appear on the display.
3. It will automatically check whether the arm cuff is applied correctly during the measurement process. When the cuff is applied correctly, is displayed, otherwise is displayed, need to reapply the arm cuff. In very rare cases, higher pressure inflation may be required. At this point, the monitor will automatically re-inflate to about 40mmHg higher than the initial inflation, and then re-measure, without affecting the measured value.
4. When the measurement is complete, the blood pressure and pulse rate will be saved automatically. Press the START/STOP button to turn the monitor off. Or the monitor will automatically switch off after two minutes of inactivity.
5. Unplug the cuff joint from the blood pressure monitor, and gently not forcefully fold the air tube into the cuff.

Viewing Memory Values The monitor automatically stores up to 90 sets of measurement values for each user.
Turn off the unit.
Step1: press the MEM button, and an average of the last three sets of measurement values displays first on the screen.

Deleting Memory Values In shutdown mode, press and hold the MEM button, after about 3 seconds press the SET button at the same time, and “ ” appears on the display, which means all the memories have been deleted.

Bluetooth connection

The Bluetooth function (Bluetooth version: BLE5.0) will be automatically turned on when the monitor is powered on. The external receiver can search and connect to the monitor. The Bluetooth symbol “ ” lights up when connect successfully. After measurement, the monitor will send the measurements to the receiver.

Care and Maintenance

Cleaning the monitor and cuff
