Omron MIT3 - Automatic Blood Pressure Monitor Manual

Introduction

Thank you for purchasing the OMRON MIT3 Automatic Blood Pressure Monitor.
Your new blood pressure monitor uses the oscillometric method of blood pressure measurement. This means the monitor detects your blood 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.

Intended Use
This device is a digital monitor intended for use in measuring blood pressure and pulse rate in adult patient population. The device detects the appearance of irregular heartbeats during measurement and gives a warning signal with the measurement result.

Please read this instruction manual thoroughly before using the device.
Please keep for future reference. For specific information about your own blood pressure, CONSULT YOUR PHYSICIAN.

Display symbols

Irregular Heartbeat Symbol

Normal Heartbeat

Irregular Heartbeat

When the monitor detects an irregular rhythm two or more times during the measurement, the irregular heartbeat symbol will appear on the display with the measurement values.

An irregular heartbeat rhythm is defined as a rhythm that is 25% less or 25% more than the average rhythm detected while the monitor is measuring the systolic and diastolic blood pressure.

If the irregular heartbeat symbol displays with your measurement results, we recommend you consult your physician. Follow the directions of your physician.

Cuff Wrap Guide Symbol

If the cuff was wrapped too loosely, it may cause unreliable values. If the wrapping of cuff is too loose, the cuff wrap guide symbol appears.
Otherwise appears. This is the function which is used as an aid in determining if the cuff is wrapped snugly enough.

Blood pressure Level Indicator

Blood pressure level indicator will light up between the systolic blood pressure and the diastolic blood pressure. If your systolic or diastolic pressure is above the standard range (135 mmHg for the systolic blood pressure and/or 85 mmHg for the diastolic blood pressure), the heartbeat symbol will flash when the measurement result is displayed.

2013 ESH/ESC Guidelines for the management of arterial hypertension
Recent research suggests that the following values can be used as a guide to high blood pressure for measurements taken in office or at home.

Before Taking a Measurement

To help ensure an accurate reading, follow these directions:

1. Avoid bathing, drinking alcohol or caffeine, smoking, exercising and eating for 30 minutes before taking a measurement. Rest for at least 15 minutes before taking the measurement.
2. Stress raises blood pressure. Avoid taking measurements during stressful times.
3. Measurements should be taken in a quiet place.
4. Remove tight-fitting clothing from your arm.
5. Sit on a chair with your feet flat on the floor. Rest your arm on a table so that the arm cuff is at the same level as your heart.
6. Remain still and do not talk during the measurement.
7. Keep a record of your blood pressure and pulse readings for your physician. A single measurement does not provide an accurate indication of your true blood pressure. You need to take and record several readings over a period of time. Try to measure your blood pressure at the same time each day for consistency.

Preparation

Battery Installation

1. Remove the battery cover.
2. Insert 4 "AA" batteries as indicated in the battery compartment.
3. Replace the battery cover.
