Blood pressure can be taken on either the left or right arm. However, for accuracy, it is generally recommended to take the measurement on the same arm each time to ensure consistent results.
The American Heart Association (AHA) recommends using the arm with the higher pressure as the measurement site. This is because blood pressure can be slightly different in each arm, and using the arm with the higher pressure can provide a more accurate reading.
It is also important to use the correct cuff size for the individual being measured, as using a cuff that is too small or too large can result in inaccurate readings. In addition, it is recommended to take blood pressure measurements at the same time each day, and to avoid taking measurements after exercise or consuming caffeine, which can temporarily elevate blood pressure.
