In the modern world, where people are constantly in a hurry somewhere and work a lot, forgetting about themselves, it is important to pay attention to your health. In particular, it is always necessary to monitor blood pressure in order to prevent hypertension. The normal vital activity of the organism, its continuous functioning, depends on this. To measure pressure, a tonometer is required.

The device and principle of operation
To measure pressure with a tonometer, a special cuff is placed on the shoulder of the patient. In semi-automatic models, fluctuations in air pressure in this cuff are recorded. Such pressure is created under the influence of blood flow in the area of the artery, which is clamped by the cuff.
Semi-automatic models of tonometers imply the absence of a compressor, air must be pumped manually with a pear. The principle of operation in semi-automatic tonometers is oscillometric. As soon as the necessary pressure is reached, the tonometer automatically discharges air.
Some time after processing the data by the built-in tonometer microprocessor, the result of measuring systolic (when blood passes through the compressed artery) and diastolic pressure (when blood flows freely through the artery) appears on the screen of the device.
Advantages and disadvantages
Like any tonometer model, semi-automatic models have their advantages and disadvantages. How significant they are, it is up to buyers to decide, because what is completely acceptable for some, for other users is categorically unacceptable.
Among the advantages should be noted ease of use. Even a person who is not savvy in medicine can easily measure his own pressure at home. Learning to use a semi-automatic blood pressure monitor will not be difficult even for older people, and it is they who are the most active buyers of this product.
If we talk about the minuses of the semiautomatic device, then it is worth focusing on some measurement errors. But in most cases, an error of 10-15 mmHg occurs due to the fact that the patient himself pumps air with a pump, thereby stimulating blood flow and artificially increasing his pressure. Therefore, of course, it is better if the measurement of pressure is carried out by another person or health worker.
The best models
What is the best semi-automatic blood pressure monitor in terms of users? It is an accurate and uncomplicated device. Accuracy is necessary to obtain reliable data on which medication, a doctor's appointment, etc. depend. The ease of operation is also important for buyers, because if the device is complex, then a person who is far from medicine will have difficulty measuring pressure.
“A good blood pressure monitor is an expensive blood pressure monitor.” This is the opinion among some buyers. But this is not always justified. Indeed, most often the buyer overpays money not so much for quality as for brand. That is why it is very important to understand the tonometer companies and determine the most optimal option, both in quality and price.
To choose the best model for yourself, consider the ranking of the best semi-automatic tonometers of 2019.
