There is no significant difference between the results of the left and right arms of the sphygmomanometer, and there is no research to show which is more accurate.
Measurement of blood pressure in the clinic to take the sphygmomanometer to cuff pressure method, the actual operation process, often need to measure the blood pressure for two consecutive times, if necessary, can be measured in both arms of the blood pressure, the general difference will not be more than 10mmHg, the blood pressure test results need to be based on the average of the results of the two measurements. If the difference between the two readings is more than 5mmHg, a third measurement is required and the average of the three measurements is taken.
If the difference between left and right arm blood pressure values is too large, it is necessary to consider whether there is subclavian artery blood theft or obvious vascular stenosis, etc. It is recommended to actively seek medical advice and improve vascular ultrasonography under the guidance of the doctor for further clarification.
If there is any blood pressure abnormality, you should consult a doctor promptly and follow the doctor’s instructions for treatment.
