According to statistics, the number of people with blood pressure in China has exceeded 330 million, which means that one out of every 3-4 adults in China suffers from hypertension. Along with the increasing incidence of hypertension, the knowledge of hypertension has been widely popularized and people’s awareness of hypertension has grown. At the same time, along with the widespread use of electronic sphygmomanometers, almost every household has a sphygmomanometer, and everyone can take their blood pressure at any time. So, the question arises, blood pressure, you measured the right? Some people may question: what is difficult to measure blood pressure, is not the blood pressure monitor cuff tied to the arm, a button, the value will read out? What is the right measurement of the right say? In fact, it is not true, the blood pressure measurement still needs to be the correct method, the wrong measurement method to obtain inaccurate measurement values, sometimes it is better not to measure. Here, we will talk about how to measure blood pressure correctly. Choose the right blood pressure monitor Now commonly used to the family blood pressure monitor is generally electronic blood pressure monitor, compared to the mercury column blood pressure monitor, its operation is simple, one person can also be convenient to complete. Electronic sphygmomanometers are mainly divided into arm sphygmomanometers, wrist sphygmomanometers, and finger sphygmomanometers. The wrist sphygmomanometer and finger sphygmomanometer will produce errors in blood pressure measurement for patients with microcirculation disorders and high blood viscosity, therefore, it is recommended that you prefer the arm sphygmomanometer. And choose a blood pressure monitor that conforms to the international standard certification. Preparation before measurement 1.No strenuous exercise for 30 minutes before the blood pressure measurement, and rest quietly for at least 5 minutes. 2.Empty your bladder before the blood pressure measurement, and do not hold urine. 3, avoid smoking, drinking alcohol, coffee and strong tea. Measurement posture 1.Sitting position, you need to choose a chair or sofa with a backrest, relax your body, both feet on the ground, not crossed. 2.Supine position in bed. Measurement method 1.Take off the jacket first, expose the upper arm, place the elbow at the same level as the right atrium (flat fourth rib cartilage in sitting position, flat mid-axillary line in supine position), and abduct the arm 45° with the palm up. 2.Wrap the cuff around the upper arm, with the lower edge of the cuff 2-3 cm from the elbow fossa, and the degree of tightness is such that a finger can be inserted between the cuff and the arm. 3.Press the start button of the sphygmomanometer to start measuring blood pressure and read the value. 4.Loosen the cuff, rest for 1-2 minutes, measure again and take the average of the two blood pressures. If the difference between the two systolic or diastolic blood pressures is greater than 5 mmHg, take three blood pressure measurements and take the average of the three blood pressures. Caution During the measurement, the body is relaxed, and there is no talking, no activity, no smoking, no drinking and no use of cell phones. There can be a difference of 5-10mmHg between the blood pressure of the two upper extremities in normal people, and the blood pressure at different times of the day fluctuates constantly, so do not panic and measure the blood pressure repeatedly and frequently because the blood pressure on both sides or at two points in time is not equal. Warm tips to monitor blood pressure should be fixed time, fixed posture, fixed measurement limbs, record the blood pressure value, retain the data, so that doctors can understand your blood pressure situation in detail.
