This often happens in hospitals. Patients say that their blood pressure is high, but when they go to the hospital, their blood pressure is normal. Recently, 100 patients were investigated by the Department of Cardiology of the hospital, and less than 5% of them can correctly measure blood pressure. The director of the department said that the blood pressure of the same person is different at the same time because of the influence of posture and emotion, and the maximum difference can be 10mmhg, which causes some patients to misjudge their blood pressure, delay their illness or overuse drugs.
17th is World Hypertension Day, and this year’s theme is "Know Your Blood Pressure". The reporter interviewed the director of cardiology and asked the doctor to teach you how to measure your blood pressure.
Posture influence
Legs cocked, low blood pressure rose by 6mmhg. Doctor: Blood pressure is different with different force.
At 14: 00 on the 16th, the reporter measured his blood pressure in the cardiology clinic, and sat in the correct posture as instructed by the director. At this time, his blood pressure was 132/88. After rest, the left arm was measured in the same posture, and the blood pressure value was 132/86. The director said that the blood pressure values of the left and right arms are different. Normally, the blood pressure value of the right arm should be high. If the left side is high, arteriosclerosis may occur. When continuously measuring blood pressure, the interval should be more than 2 minutes to ensure vasodilation, otherwise the blood pressure value will be inaccurate.
Five minutes later, according to the director’s instructions, the reporter tilted his legs and left the back of the chair. At this time, the measured value is 130/94, the high pressure drops by 2mmhg, and the low pressure rises by 6mmhg. The director said that after changing posture, the degree of exertion changed, and the blood pressure also increased. This measurement is also inaccurate.
◎ Focus on the correct posture for measuring blood pressure: sitting upright, leaning back against the back of the chair, landing on both feet, putting your arms on the armrest and table, and measuring blood pressure with your right arm.
Emotional influence
The last time I went to the toilet, the pressure dropped by 4mmhg.
Doctor: If you hold your urine tight, your blood pressure will rise.
At 14: 20, after drinking a lot of water, the reporter measured the blood pressure again according to the director’s request. At this time, the blood pressure value of the right arm was 133/90. After taking a two-minute rest after going to the toilet, the blood pressure value was measured again, which was reduced to 130/86.
The doctor said that when people hold their urine, they are mentally nervous, so their blood pressure will rise accordingly. After emptying the bladder, people’s body and mind will unconsciously relax. At this time, taking a correct posture to measure blood pressure is the real blood pressure value.
◎ Focus on the correct measurement state: the self-measured blood pressure value is a reference value, and only when the posture and state are the same every time can blood pressure be effectively monitored. Therefore, to ensure the correct posture, rest quietly for 5 minutes, ban smoking or drinking coffee within 30 minutes, and empty the bladder, which is the standard measurement state.
Listen to a joke: high blood pressure rises by 5mmhg. Doctor: Blood pressure will rise regardless of sadness or joy.
"Blood pressure is controlled by emotions. Some people think that people who are irritable have high blood pressure. In fact, regardless of sadness or joy, people’s blood pressure will rise."
At 14: 40, the director told a joke when taking blood pressure. After the reporter laughed, the blood pressure value was 135/94, which was 5mmhg higher than before. Because it was not accurate, the blood pressure value was measured again within 1 minute, and it was 138/95, and then it was 141/95. People with normal blood pressure have detected high blood pressure.
People’s blood pressure is controlled by emotions, and it will fluctuate after emotions, and the blood pressure value will fluctuate by 2-10mmhg, which means that some people will have a cerebral infarction or myocardial infarction because of their high blood pressure after being overjoyed or furious.
◎ Focus on the correct measurement interval: blood pressure measurement should be repeated at intervals of more than 2 minutes, and the average of the two readings should be taken for record. If the interval is not enough, the blood vessels can’t relax effectively, which will make the blood pressure rise, and each time it is higher than the last time, which will easily make patients misjudge and take antihypertensive drugs excessively.
