Electronic Tonometer

Taking care of one's own health is the responsibility of each of us. Of course, diagnosing the disease and drawing up a scheme for its effective treatment is the prerogative of doctors, but if there are high-quality medical devices at home, then the ailment can be noticed on time and independently. Such devices include also tonometers , which make it possible to measure blood pressure in the arteries. There are many kinds of these assistants, but for home use, electronic tonometers are increasingly being chosen, the accuracy of which is high, and operation is very simple.

The device and the principle of operation

The electronic tonometer works, like any other electronic device, based on the physics processes. First, it is necessary to pump air into the cuff to increase the pressure by 30-40 units, and then turn on the bleeding function. During decompression, the tonometer program reads the data from the sensor of the main unit through the tubes that divert air. The sensor itself captures the pressure changes and pulse waves that pass through these tubes from the cuff. Special algorithms allow the device to calculate the value of blood pressure, the value of which is displayed on the display. The device of the electronic tonometer, consisting of a cuff and a housing with a power supply, a chip and a display, is based on the fact that as a result of contact with the skin (veins and arteries), data is read and their subsequent automatic processing.

And now about how to measure the pressure of an electronic tonometer. First, you need to take a comfortable pose, calm down, do not move your hands and feet. Even thoughts that cause an emotional outburst can affect the results of the measurement. Fix the cuff to the wrist or forearm, relax the hand and press the button on the device. That's all!

Choosing a Tonometer

If you often have to measure pressure, then there is no doubt as to which is better to choose a tonometer, no, of course, electronic. The quality of the measurement is equally good for both electronic and mechanical models, but you do not have to use a phonendoscope and a manometer. It is enough to put an electronic blood pressure monitor on your wrist or forearm, and after a few seconds you can see the result of the measurement on the instrument display. In addition, the choice and purchase of an electronic tonometer is an opportunity to measure at home not only pressure, but also a pulse. There are also modern models with a number of additional functions. So, the digital tonometer can be equipped with memory, sound indicators (scoring the results), backlight, clock and calendar. Use such a device is convenient, but it is more expensive than a mechanical analog.

As for the modification, it is better for elderly or often sick people to purchase a tonometer with a shoulder, rather than a wrist, cuff. Automatic models allow you to measure pressure by pressing just one button. No pears that inflate the air, in such models no. Why not an option with a wrist cuff? Because people older than forty years, the pulse on the wrist is most often weakened, torments atherosclerosis and other changes associated with age. This affects the operation of the tonometer and the readings may be incorrect. But for athletes who need to control pressure and pulse during training, the tonometers, which are worn on the wrist, are the best solution.

Before you choose and purchase an electronic blood pressure monitor, consult a pharmacist, or even better - with your doctor. In the pharmacy, be sure to test the device, read the documents confirming its quality. And do not forget to issue a warranty card for the tonometer.
