A blood pressure monitor is a special device for measuring blood pressure levels. It allows you to control this volatile, but such an important parameter of human health. In most cases, it is difficult to understand without a tonometer: hypotension or a hypertensive crisis is in front of you, because the symptoms are very similar: weakness, dizziness, headache. Only by measuring the pressure, you can provide first aid.
The pharmacy has a large selection of devices. It is difficult to determine which model is needed in a particular case. Devices differ in price, quality, mechanism of action, country of manufacture. What to look for? Tonometers are mechanical and electronic (automatic and semi-automatic). Before deciding which option is better, you need to understand the specifics of each of them.
A good old device, which is familiar to us from childhood. This is the device used in most hospitals. A cuff is put on just above the elbow joint, air enters it with the help of a pear, then the doctor releases air with precise coordinated movements until he hears a tone and records the indicators. The mechanical device is durable, it is difficult to disable it, the cost is usually more affordable.
One of its major drawbacks is its complexity in use. In old age, it is difficult to properly pump and release air, see the vibrations of the tonometer needle or hear the tones. This blood pressure monitor is ideal for healthcare professionals.
Many people are wondering how to choose an automatic blood pressure monitor. Unlike mechanical, it has many varieties and additional functions. The electronic device is convenient in that blood pressure indicators are displayed on the display. Distinguish between automatic and semi-automatic tonometers.
Automatic - this option practically does not require human intervention, it is fixed on the arm, then blood pressure is measured independently. The “smart” device shows ready-made indicators and also interprets the result. If the patient does not understand the degree of hypertension, the tonometer will write or announce the diagnosis. It is a good choice for seniors.
Main disadvantages: breakdowns are possible, since the electronic mechanism is more sensitive to changes in the external environment, mechanical damage. The cost of such a device is higher, additional functions (voice notification, indicator of arrhythmia, pulse) only increase its price.
The semi-automatic tonometer combines the positive aspects of the above pressure measuring devices. Air is pumped into the cuff using a pear, thereby relieving the work of the electronic mechanism. Less energy is consumed and the appliance lasts longer. Then the tonometer measures the pressure on its own. The value for money in this model is very good.
Even a healthy young man sometimes finds it difficult to properly pump up the cuff, slowly release the air, and hear the tones. In old age, it is almost impossible to perform these actions. Therefore, it is better to choose an electronic version of the tonometer.
If a person lives alone, the tonometer should be convenient for him.
If there is little strength in the hands, a stroke has been suffered, fully automatic models should be chosen. In this case, the tonometer will do everything by itself, you just need to fix it on your arm.
Heart rate detection is an optional feature. Of course, you can independently calculate the heart rate, but this can be done by the device. Then you have to pay extra for a more expensive model.
If you have vision problems, you should choose a blood pressure monitor with a large display. Modern models are equipped with voice announcements. After measuring the pressure, the device will sound the indicators, as well as the diagnosis according to the classification (norm or degree of arterial hypertension).
