What is a blood pressure meter?

Sphygmomanometer is a medical device used to measure human blood pressure, including manual sphygmomanometer, automatic sphygmomanometer, electronic sphygmomanometer, etc. Its accuracy is very important. The normal range of blood pressure varies from person to person, hypertension and hypotension may cause harm to the body. When using sphygmomanometer, pay attention to the correct method and maintenance calibration. Special treatment may be required for blood pressure measurement of special groups. When purchasing a sphygmomanometer, you should choose a regular channel and a suitable product. A sphygmomanometer is a medical device used to measure human blood pressure. It can help doctors or patients understand the level of blood pressure for diagnosis and treatment. The following are some important information about sphygmomanometers: 1. Definition and measurement of blood pressure: Blood pressure refers to the pressure on the wall of blood vessels when blood flows in blood vessels. Systolic blood pressure is the pressure inside the blood vessel when the heart contracts, diastolic blood pressure is the pressure inside the blood vessel when the heart relaxes. The sphygmomanometer determines the blood pressure level by measuring these two values. 2. Types of sphygmomanometers: There are many types of sphygmomanometers, including manual sphygmomanometers, automatic sphygmomanometers, electronic sphygmomanometers, etc. Manual sphygmomanometers require manual inflation and deflation by doctors or patients, while automatic and electronic sphygmomanometers can automatically measure blood pressure. 3. Accuracy of sphygmomanometers: Accuracy of sphygmomanometers is very important, and inaccurate sphygmomanometers may lead to misdiagnosis or mistreatment. Therefore, when selecting sphygmomanometers, certified, accurate and reliable sphygmomanometers should be selected. 4. Normal range of blood pressure: Normal range of blood pressure varies from person to person, but in general, systolic blood pressure is between 90 - 140 mmHg and diastolic blood pressure is between 60 - 90 mmHg. If blood pressure exceeds this range, it may be diagnosed as hypertension or hypotension. 5. Hazards of hypertension: Hypertension is a common disease. If it is not treated in time, it may lead to serious complications such as heart disease and cerebrovascular disease. Therefore, patients with hypertension need to measure their blood pressure regularly and treat them according to their doctor's advice. 6. Hypotension hazards: Hypotension may also lead to dizziness, fatigue and other discomfort symptoms. If severe hypotension is severe, it may lead to shock. Therefore, patients with low blood pressure also need to pay attention to monitoring blood pressure and seek medical advice in a timely manner. 7. How to use the sphygmomanometer: When using the sphygmomanometer, you should operate according to the instructions on the manual. Generally speaking, it is necessary to let the patient rest for a period of time, and then tie the cuff of the sphygmomanometer on the patient's upper arm, adjust the position and start measuring. Keep quiet and do not speak or move when measuring. 8. Maintenance and calibration of sphygmomanometers: sphygmomanometers need regular maintenance and calibration to ensure their accuracy. In general, manual sphygmomanometers need to regularly check the tightness and accuracy of the cuff, and automatic sphygmomanometers and electronic sphygmomanometers need regular calibration. 9. Blood pressure measurement for special populations: For some special groups, such as pregnant women, the elderly, athletes, etc., blood pressure measurement may be different. Therefore, when measuring the blood pressure of these groups, it should be adjusted according to the specific situation. 10. Purchase and selection of blood pressure meter: When purchasing blood pressure meter, you should choose regular channels to purchase, and pay attention to check the product certification and instructions. At the same time, you should choose the right blood pressure meter according to your needs and budget. In short, the blood pressure meter is a very important medical device, which can help us understand the blood pressure level for diagnosis and treatment. When using the blood pressure meter, attention should be paid to accuracy, use method and maintenance calibration to ensure the accuracy and reliability of the measurement results.
