Are Wrist Blood Pressure Monitors as Accurate as Arm Blood Pressure Monitors?272

Wrist blood pressure monitors are becoming increasingly popular, as they are more convenient and portable than traditional arm blood pressure monitors. However, some people question whether wrist blood pressure monitors are as accurate as arm blood pressure monitors.

The answer to this question is not entirely straightforward. In general, arm blood pressure monitors are considered to be more accurate than wrist blood pressure monitors. This is because the artery in the upper arm is larger and easier to measure than the artery in the wrist. Additionally, the position of the arm during measurement can affect the accuracy of the reading. When using a wrist blood pressure monitor, it is important to keep the arm at the same level as the heart.

However, some studies have shown that wrist blood pressure monitors can be just as accurate as arm blood pressure monitors, provided that they are used correctly. In one study, researchers found that a wrist blood pressure monitor was just as accurate as an arm blood pressure monitor in measuring blood pressure in people with normal blood pressure. However, the wrist blood pressure monitor was less accurate in measuring blood pressure in people with high blood pressure.

Another study found that wrist blood pressure monitors were less accurate than arm blood pressure monitors in measuring blood pressure in people with atrial fibrillation. Atrial fibrillation is a heart condition that can cause irregular heartbeats. The irregular heartbeats can make it difficult to get an accurate blood pressure reading.

Overall, the evidence suggests that wrist blood pressure monitors are not as accurate as arm blood pressure monitors, but they can be just as accurate if they are used correctly. If you have high blood pressure or atrial fibrillation, you should use an arm blood pressure monitor.

Here are some tips for using a wrist blood pressure monitor accurately:
Sit in a comfortable chair with your feet flat on the floor.
Rest your arm on a table or other flat surface.
Place the cuff on your wrist, about 1 inch above the crease in your wrist.
Wrap the cuff snugly around your wrist, but not too tightly.
Press the start button and wait for the reading to appear.
Record the reading and compare it to your previous readings.

If you have any questions about using a wrist blood pressure monitor, talk to your doctor.
