What are the four criteria for measuring blood pressure

Blood pressure is measured at a fixed position, at a fixed position, at a fixed sphygmomanometer and at a fixed time.

1. Blood pressure at a fixed position

needs to be measured at a fixed position, generally at the upper arm, because the blood pressure of the left and right arms of the human body is not consistent, so the blood pressure is measured at the same position every time.

2. Blood pressure at a fixed position cannot be measured this time

in a sitting position and the next time in a lying position. The blood pressure value is not accurate and needs to be maintained in a consistent position.

3. Blood pressure at a fixed position needs to be

measured in a fixed sphygmomanometer, whether electronic or mercury.

4. Blood pressure at a fixed time

should be measured in a fixed time period every day in order to compare and analyze the blood pressure at the same time in the past.
