Blood pressure fluctuation range varies from person to person, but in a quiet state, systolic blood pressure is generally in the 90/120mmHg is normal, diastolic blood pressure is generally in the 60/80mmHg is normal.
Human blood pressure is not constant, but fluctuates within a certain range, strenuous activities to be slightly higher than the quiet state blood pressure, systolic blood pressure is generally 90/120mmHg fluctuations for normal, diastolic blood pressure is generally 60/80mmHg for normal.
Bilateral upper extremity blood pressure difference of 5~10mmHg is normal, upper and lower extremity blood pressure difference is generally 20~40mmHg, pulse pressure is generally 30~60mmHg, pulse pressure = diastolic pressure + 1/3 pulse pressure difference.
The range of blood pressure fluctuation varies from person to person, but under normal circumstances, the fluctuation will not exceed 20mmHg. Abnormalities should be consulted in time, and attention should be paid to maintaining adequate rest.
