When is the most accurate time to measure blood pressure

summary

Blood pressure control in a certain range can not only delay the damage of target organs, but also reduce the incidence of stroke, coronary heart disease and sudden cardiac death. It is the basis of effective control of blood pressure to know the value and fluctuation of blood pressure regularly and accurately. The blood pressure of human body is not invariable. Even the blood pressure of normal people will fluctuate by 30mmhg within one day. So, how to measure blood pressure accurately?

When is the most accurate time to measure blood pressure

First: [best time] ① the best time to measure blood pressure is within 1 hour after getting up in the morning or before going to bed in the evening. If the morning measurement, please wake up within 1 hour, after urination, before breakfast (if you are taking antihypertensive drugs, then before taking medicine). If the measurement is done at night, it is recommended to do it before bedtime. If it's any other time, it's better to measure when both body and mood are stable. In addition, it is recommended to measure at the same time every day. ② Please measure at the same time every day.

Second: [correct measurement method] the following is the schematic diagram of the measurement method of arm type and wrist type electronic sphygmomanometers. Keep quiet during the measurement, stretch your arms naturally and lay them flat on the table, and pay attention to the bandage keeping the same level with your heart.

Third: [precautions for measurement] ① the factors causing the change of blood pressure include: action, mental state, emotion, diet, drinking, urination, defecation, conversation, environmental change, temperature change, smoking, etc. The blood pressure was the highest at work, and gradually decreased in the afternoon and evening. The blood pressure was lower during sleep and gradually increased after getting up. ② Blood pressure measured at home may be lower than that measured in hospitals and medical institutions. This is because it is easy to be nervous in the hospital and relax at home. It's important to know the blood pressure in a stable state at home. ③ The blood pressure of wrist may be different from that of upper arm. The blood pressure measurement of wrist may be slightly different from that of upper arm due to the difference of measurement position and blood vessel thickness. In most cases, the highest and lowest blood pressure of healthy people have a difference of about 10 mmHg. ④ Please rest for at least 5 minutes before measuring. Please measure quietly in a relaxed state. Please measure at about 20 ℃.

matters needing attention

After you get up in the morning, you can measure and verify the changes of blood pressure by using lying position, sitting position, standing position and other postures to determine whether there is postural hypertension. Postural hypertension generally has a good prognosis and no long-term adverse consequences, but in the diagnosis, it should be clear whether it is postural hypertension, so as to avoid unnecessary or wrong treatment measures, which will affect the physical and mental health of patients. For postural hypertension, antihypertensive drugs are generally not used. And the effect of antihypertensive drugs is not good, especially diuretics, not only can not reduce blood pressure, but will stimulate further increase of blood pressure.
