How to Read a Blood Pressure Monitor: Left or Right Arm?8

Blood pressure monitors are devices that measure the force of your blood against the walls of your arteries. They are used to diagnose and monitor high blood pressure, or hypertension. Blood pressure is measured in millimeters of mercury (mm Hg) and is expressed as two numbers: the systolic pressure and the diastolic pressure. The systolic pressure is the higher number and is the pressure in your arteries when your heart beats. The diastolic pressure is the lower number and is the pressure in your arteries when your heart rests between beats.

Blood pressure can be measured on either the left or right arm. However, it is important to always measure your blood pressure on the same arm each time. This is because blood pressure can vary slightly between the two arms.

Which arm is better to measure blood pressure on?

There is no definitive answer to the question of which arm is better to measure blood pressure on. However, there are some general guidelines that can be followed:
If you are right-handed, measure your blood pressure on your left arm. This is because the left arm is closer to your heart than the right arm, and therefore the blood pressure reading will be more accurate.
If you are left-handed, measure your blood pressure on your right arm. This is because the right arm is closer to your heart than the left arm, and therefore the blood pressure reading will be more accurate.
If you have a history of high blood pressure, measure your blood pressure on both arms and take the average of the two readings. This will give you a more accurate reading of your blood pressure.

How to measure your blood pressure

To measure your blood pressure, you will need a blood pressure monitor. Blood pressure monitors are available at most pharmacies and medical supply stores. You can also purchase a blood pressure monitor online.

Once you have a blood pressure monitor, follow these steps to measure your blood pressure:
Sit in a comfortable chair with your feet flat on the floor and your back supported.
Place the blood pressure cuff on your upper arm, about 1 inch above the elbow. Make sure the cuff is snug but not too tight.
Close the cuff and press the start button. The blood pressure monitor will automatically inflate the cuff and measure your blood pressure.
Once the cuff has inflated, the blood pressure monitor will display your blood pressure reading.

Interpreting your blood pressure reading

Once you have your blood pressure reading, you need to interpret it. Blood pressure readings are classified as follows:
Normal blood pressure: Systolic pressure less than 120 mm Hg and diastolic pressure less than 80 mm Hg
Prehypertension: Systolic pressure between 120 and 139 mm Hg or diastolic pressure between 80 and 89 mm Hg
Stage 1 hypertension: Systolic pressure between 140 and 159 mm Hg or diastolic pressure between 90 and 99 mm Hg
Stage 2 hypertension: Systolic pressure 160 mm Hg or higher or diastolic pressure 100 mm Hg or higher
Hypertensive crisis: Systolic pressure 180 mm Hg or higher or diastolic pressure 110 mm Hg or higher

If your blood pressure reading is high, it is important to talk to your doctor. High blood pressure can lead to serious health problems, such as heart disease, stroke, and kidney disease.
