Teach you a trick: How to test blood pressure to be accurate

For a long time, the typical method of blood pressure measurement has been artificial ausion with water pillar or mechanical hydraulic blood pressure meter. However, due to the advantages of repeated standardized technologies and the advantages of eliminating the deviation of observer, in clinical practice, it has gradually changed to automated devices. As described in its latest blood pressure measurement proposal, as described by the American Heart Association (AHA), the (automatic) device used by the clinic can replace both the traditional (manual) readings or as their supplement. “However, AHA still recommends that in the daily office measurement, it should be equipped with appropriate maintenance manual blood pressure monitor.

Another observation result of the American Heart Association is that although the auspicious method has been a standard for blood pressure measurement for more than 50 years, the survey shows that doctors rarely follow the guidelines of use. But this is an important place for blood pressure measurement, so we recommend the main points of manual blood pressure measurement to all medical professionals here.

The first step, select the correct device

1. High -quality ausion

2. Appropriate sizes of blood pressure cuffs

3. Blood pressure meter, such as a hydraulic gas pressure meter or a silver column blood pressure meter or an automatic device with a manual inflatable mode

Step 2, patient preparation

Make sure the patient relax for 5 minutes before measurement. Patients should sit upright, the upper arm position should be flat with the heart, and their feet are flat on the floor. Take off the extra clothes, these clothes may interfere with blood pressure sleeve straps or restrict the blood flow of the arms. Make sure that you and the patient should not speak during the test.

Step 3, choose and wear blood pressure cuff bands

Most measurement errors are caused by the size of the sleeve strap without spending time. Wear the sleeve on the patient’s arm and use an index to determine whether the patient’s arm perimeter is within the range. Otherwise, choose the appropriate smaller or larger sleeves.


Touch and locate the anexia and position the blood pressure cuffs, so that the arteries are pointed to the aeral artery. Estimated the blood pressure sleeve tightly on the arm.

Step 4-Positioning Activaler

On the same arm of the blood pressure sleeve strap, the forehead fossa (crease of the arm) of the palpation is located to locate the strongest pulse sound, and the bell of the stethoscope is placed above the aneurysm of the position.

Step 5-Blood of Blood pressure meter is inflated

When you hear the sound of pulse, start to inflatable the bulb with the sleeve. When the sphygmoman cuff belt is swollen to enough to stop the blood flow, the stethoscope should have no sound. The reading of the pressure gauge should be higher than the normal blood pressure reading of 30 to 40mmHg. If the value is unknown, the sleeve band can be inflated to 160-180 mmHg. (If the pulse sounds immediately, it will be inflated to higher pressure.)

Step Six-Slowly Powder BP Sleeve Band

Start lipping. The US Heart Association suggested that the pressure should decrease at the rate of 2-3 mm Hg at 2-3 mm per second, and any faster speed may cause inaccurate measurement.

Step 7-Drawing and diastolic pressure reading number

When the blood began to flow through the arteries, the first time I heard the rhythmic sound of the patient’s systolic blood pressure, this may be similar to the sound of knocks. Continue to listen to the pressure of blood pressure sleeve bands and the sound disappear. When a rhythmic sound stops, pay attention to the readings of the instrument. This will be the number of diastolic reading.

Step 8-Repeated inspection accuracy


The American Heart Association recommends reading reading with both arms and average reading. To check whether the pressure is accurate again, wait between two readings for about 5 minutes. Generally speaking, blood pressure is higher in the morning and lower at night. If there is a problem with blood pressure reading, or suspected hidden or white fur hypertension, it may be necessary to conduct a 24 -hour blood pressure study to evaluate the patient’s overall blood pressure condition.
