Blood pressure day will have two peak

A person's blood pressure fluctuates from day to day. Understanding blood pressure fluctuation rule, for the prevention and treatment of hypertension is very meaningful.

One, the effect on blood pressure of factors

Blood pressure is the arterial blood pressure, the flow of blood to the vessel wall to produce lateral pressure, is composed of a cardiac ejection and peripheral resistance in the two force interaction results. Blood pressure, systolic and diastolic blood pressure, when during systole, arterial blood pressure rose to the highest value, called the systolic pressure; when the heart during diastole, arterial blood pressure to a minimum value, called the diastolic blood pressure. Commonly used mercury sphygmomanometer, and table type blood pressure meter, electronic blood pressure meter for measuring blood pressure. Blood pressure in the dynamic balance, emotion, environment, diet, heating and measuring method and other factors, may influence blood pressure elevation, drinking, smoking, pain, anxiety, sport,

Medication, toilet ( particularly urgent when) instantly makes the fluctuation of blood pressure. Ask for this:

1 measurements of blood pressure before the half hour to drink, do not drink tea and not smoking, peace of mind, emptying the bowels, no longer eat.

2 measurements of blood pressure before the calm and rest for 15 minutes.

3 blood pressure and heart the same level.

4 avoid compression arm sleeve. Sphygmomanometer cuff and arm front arterial gas to maintain proper tightness.

5 blood pressure meter gas sleeve gas should be completely free.

In two, the daily blood pressure has two peak periods

Most people have obvious diurnal rhythm of blood pressure, namely daytime activity when the blood pressure is high, after sleeping at night with low blood pressure. The general daytime blood pressure of two peaks, i.e. at 6～ 10 and 4～8. Therefore, in the two period to measure blood pressure, can know the day of blood pressure at the highest point. The day the highest values of blood pressure in two hours, then decreased gradually, until 1～ 2

When blood pressure minimum value, namely the second valleys, finally gradually rise again into the next day's first peak. Blood pressure day night low difference and human biological clock, is also the neural, humoral, endocrine and other comprehensive regulation results. When the human body biological clock changes, blood pressure will change, such as night shift nurses, workers, staff on duty, daily blood pressure peak may appear in the night.

Three, blood pressure peak times significance

1 understand a person's blood pressure value, to select in the two peak period measurement, can reflect the blood pressure.

2 in the peak period of continuous measurement of blood pressure in 3, taking the average value, when the systolic or diastolic blood pressure≥ 140mmHg≥ 90mmHg, can be diagnosed as hypertensive; left the peak period for measuring blood pressure, may be missing the diagnosis of hypertension.

3 every day at the same peak measurements of blood pressure, blood pressure level. If the day in the morning blood pressure, another day in the afternoon, measurement, so it is difficult to compare the level of blood pressure.

4 in blood pressure peak period prior to the use of blood pressure lowering drugs, hold short effect, in effect, the antihypertensive effect of long-acting formulations. And use of little significance.

5 in case of hypertension patient medication effect is poor, to find the cause of elevated blood pressure causes, whether there are complications of hypertension, the drugs used to whether satisfy the need. In addition, must seek to understand the daily blood pressure peak period, find out the changes of blood pressure, take corresponding treatment method.
