Is it accurate to measure blood pressure while lying down?

The method of measuring blood pressure is very simple now. In addition to hospitals, many clinics can measure blood pressure, and there are also many communities that provide free blood pressure measurement services. However, we must remind everyone that there are many precautions when measuring blood pressure, such as not measuring blood pressure when you are nervous. In addition, if you want the measurement results to be accurate, you must choose the right time to measure blood pressure, etc. Most people measure their blood pressure while sitting, but some patients need to measure their blood pressure while lying down. Are the blood pressure measurement results accurate in this way?

Is it accurate to measure blood pressure while lying down?

I was sitting in the hospital and my blood pressure was measured at 140/102 mmHg, which is high blood pressure. Blood pressure measured while lying down was 118/79 mmHg, which is normal. Which one is accurate?

Netizen: The measurement when standing is 90/60mmHg, when sitting is 115/75mmHg, and when lying down is 140/80mmHg. Which result should I believe?

In order to measure blood pressure accurately, you need to clarify the following questions?

1. Is it better to measure blood pressure while sitting, standing or lying down? What are the requirements?

1. Generally, blood pressure measurement requires the person being measured to sit down, which means in an outpatient clinic. If blood pressure is measured at home, the patient's condition is not serious. However, for hospitalized patients, seriously ill patients, and surgical patients, blood pressure is mostly measured in the supine position, and in standing positions in special circumstances (such as when identifying the cause of hypotension).

24-hour dynamic blood pressure monitoring, wear it on your body, and measure blood pressure in various postures such as working in the office, daily life, sleeping, etc. Regardless of the posture, the cuff of the cuff-type blood pressure monitor (arm and ambulatory blood pressure) and the wrist blood pressure monitor should be at the same level as the heart when measuring.

2. To ensure the accuracy of the measurement results, the patient's left and right upper arm blood pressure should be measured when visiting the doctor for the first time, or the measurement should be repeated at an interval of 1 to 2 minutes when adjusting the treatment plan, and the average of the two readings should be recorded. If the difference between the two readings of systolic blood pressure (high pressure) or diastolic blood pressure (low pressure) is more than 5 mmHg, it should be measured again and the average of the three readings should be recorded.

3. Human blood pressure fluctuates (like the waves in the sea), it is not always constant. It is also related to many factors, including exercise, whether the environment is quiet, whether the mood is tense, indoor temperature, light, whether smoking or drinking coffee before measurement, whether the bladder is empty, etc. A diagnosis cannot be made based on a single blood pressure measurement.

2. What is the difference between blood pressure monitoring for normal people and patients with hypertension?

1. It is normal for normal people to have blood pressure that is occasionally high or low, or to rise in special circumstances such as exercise. As long as you measure your blood pressure for a few more days and find that it is basically normal, hypertension can be ruled out. But at the same time, we should also pay attention to scientific living, change bad living habits, keep a calm mind and prevent high blood pressure.

If the blood pressure is greater than or equal to 140/90 mmHg for three times (not on the same day), hypertension is confirmed and non-drug and drug treatment (when necessary) is carried out under the guidance of a doctor. If necessary, 24-hour dynamic blood pressure monitoring should be performed to rule out pseudohypertension, white coat hypertension, latent hypertension, etc.

2. Hypertensive patients monitor their own blood pressure in order to observe the effectiveness of antihypertensive drugs and changes in the condition of hypertension, and to provide doctors with more reference information by recording the results. Remember to adjust your blood pressure lowering plan and add or subtract blood pressure lowering drugs based on your blood pressure results.

For example, some patients measure their blood pressure in bed when they wake up in the morning, and then measure their blood pressure after getting up. They measure their blood pressure at the same time and in the same posture every day, and compare the blood pressure on different days, between lying and lying positions, and between sitting and sitting positions. This is still of great value.
