AB - 503 Upper Arm Cuff Blood Pressure Monitor Arm Cuff

Description:
Pay attention to your health. After buying this blood pressure monitor, read the manual thoroughly before using the device. Too frequent measurements may cause injury due to blood flow interference, please always relax a minimum of 5 minutes between measurements to allow the blood circulation in your arm to recover. It is rare that you obtain the identical blood pressure reading each time.

Features:
- Accurate reading: the digital blood pressure monitor operates on the oscillometric principle, anti-movement, and anti-noise interference, and result in more accurate readings
- One button measurement: automatic measurement with one button, easy to operate, first apply the cuff, next press the start button, then the monitor display your systolic pressure, diastolic pressure, and pulse readings
- 80 x 2 sets of memory: the monitor automatically stores measurement values up to 80 sets for each user (A and B), the guest mode can be used to take a single measurement for another user, no measurement values are stored in the memory when the guest mode is selected

Blood Pressure Measurement Q and A:
1. What is blood pressure?
The blood follows to the artery in consequence of the heartbeat (systolic and diastolic); When the heart is systolic the blood pressure from the heart to the artery is called systolic blood pressure; ager circulation around the body, the blood returns to the heart the is diastolic and the pressure is called diastolic blood pressure. Doctors can diagnose patients' blood pressure condition based on the numerical values of those pressures.

2. What is the best time to measure blood pressure?
The best time to measure blood pressure is within one hour of getting up or before going to bed at night.

3. Is digital blood pressure monitor not as accurate as vertical mercury sphygmomanometer?
According to National Standard YY 0670-2008, the errors of the oscillometric method made by digital blood pressure monitors are not bigger than vertical mercury sphygmomanometers. Meanwhile, vertical mercury sphygmomanometer which can only be applied by professional medical personnel as subject to their skills and professional judgment.

4. How to obtain accurate blood pressure valued by using the equipment?
Sit correctly, maintain the cuff at the same level as the heart and apply the cuff correctly. It is important to choose the blood pressure monitor. The digital blood pressure monitor had the anti-movement and anti-noise interference and leads to more accurate results. It is suggested to take measurements in a stable physical and mental state during other periods of the day and better at the same time each day.
