Lazle WRS-35D Wrist BP Monitors User Manual

INTRODUCTION

Thank you for purchasing this electronic blood pressure monitor. The monitor is convenient for use at home, at work, and on vacation. It is an ideal solution for people who need daily blood pressure measurements. The monitor uses the oscillometric method of blood pressure measurements. It is intended for use either by medical professionals or at home to monitor and display diastolic, and systolic blood pressure and pulse rate.

To ensure accuracy, please read and follow the instructions listed in the section titled, “APPLYING THE WRIST CUFF.” The expected device lifespan is 5 years. The device complies with international standards, including EN60601-1-2, EN60601-1, and IEC 80601-2-30 as specified in EEC directive 93/42/EEC.

INTENDED USE / INSTRUCTIONS FOR USE

This Blood Pressure Monitor is intended to measure the systolic and diastolic blood pressure, as well as the pulse rate of an adult person by using the non-invasive oscillometric technique at a medical facility or at home.

What is blood pressure?
Blood pressure is the force exerted by blood against the walls of the arteries. Systolic pressure occurs when the heart contracts. Diastolic pressure occurs when the heart expands. Blood pressure is measured in millimeters of mercury (mmHg). Your baseline, resting blood pressure should be measured first thing in the morning while still at rest and before eating.

What is hypertension and how is it controlled?
Hypertension is an abnormally high arterial blood pressure. If left unattended, it can cause a variety of health problems, including stroke and heart attack. Hypertension can be controlled by altering your lifestyle, avoiding stress, and, in certain cases, with medication as prescribed and supervised by a physician. To prevent hypertension or keep it under control:

• Do not smoke
• Exercise regularly
• Maintain a healthy weight
• Reduce salt and fat intake
• Have regular physical checkups

Why measure blood pressure at home?
Measuring blood pressure at a clinic or doctor’s office can produce an elevated reading — 25 to 30 mmHg higher than that measured at home — due to the stress associated with being at a medical facility. Home measurements reduce the effects of outside influences on blood pressure readings, supplement your doctor’s readings, and provide a more accurate, complete blood pressure history.

Blood pressure variations

An individual’s blood pressure varies greatly on a daily and seasonal basis. It may vary by 30 to 50 mmHg due to various conditions during the day. In hypertensive individuals, these variations are even more pronounced. Normally, blood pressure rises while working or engaging in physical activity and falls to its lowest levels during sleep.

Keeping these facts in mind, it is best not to become overly concerned by the results of a single measurement. However, if your concerns persist, share them with a medical professional. Take measurements at the same time every day using the procedure described in this manual. This will help you understand baseline blood pressure. Consistent daily readings will give you a comprehensive blood pressure history. Be sure to note the date and time when recording your blood pressure. Consult your doctor to interpret your blood pressure data.

PRECAUTIONS

1. If you are taking medication, consult with your doctor to determine the most appropriate time to measure your blood pressure. NEVER change a prescribed medication without first consulting with your doctor.
2. There may be variations in blood pressure values measured at the upper arm versus at the wrist for people with irregular or unstable peripheral circulation problems due to diabetes, liver disease, hardening of the arteries, etc.
3. Measurements may be unusable if this device is operated near televisions, microwave ovens, X-ray machines, mobile phone equipment, or other devices with strong electrical fields. To prevent electrical interference, use the monitor at a sufficient distance from such devices or turn them off.
4. You should always wash your hands before and after using the device.
5. Do not measure blood pressure on an arm that is being monitored by ME Equipment. Otherwise, it could cause a loss of function.
6. If you get unexpected blood pressure results, contact your doctor. Additionally, you may refer to the troubleshooting section of the manual.
7. Blood pressure readings measured at home tend to be slightly lower than hospital measurements due to a more relaxed atmosphere at home.

BLOOD PRESSURE FAQ

Why is blood pressure measured at home lower than blood pressure measured in the hospital?
Blood pressure measurements taken at home may be 20mmHg-30mmHg (2.7kPa-4.0kPa) lower than blood pressure measured in a hospital in part because many people are more nervous while at a medical facility surrounded by medical professionals. People tend to be more comfortable at home. For this reason, it is important to understand your normal blood pressure at home. Additionally, if you wear the cuff such that it sits higher than your heart, the measured blood pressure value will be lower. Please measure blood pressure while sitting in the correct posture.

Why is blood pressure measured at home higher than blood pressure measured in the hospital?
There are a number of possibilities. For instance, some anti-hypertensive drugs may lose their efficacy. In this case, follow your doctor’s instructions. Additionally, you may be using the cuff incorrectly:

• If the cuff is in the wrong position, no arterial signal will be found, and the measured blood pressure value will be higher.
• If the cuff is too loose, the compression force may fail to be transmitted to the artery, resulting in a higher measured value.
• you are bent over or sitting cross-legged, your blood pressure might be increased due to the abdominal pressure.
• If you wear the cuff such that it sits lower than your heart, the measured blood pressure value will be higher. Please wear the cuff correctly and measure blood pressure in the correct posture.

When is it best to measure blood pressure?
It is best to take measurements in the morning after using the restroom and/or when your body and mood are in a comfortable, stable state. It is better to measure blood pressure at the same time every day.
