Control of blood pressure is an important preventive procedure that avoids complications in hypertension. Determination of pressure indices in the home environment is more preferable, since in this case it is possible to exclude various factors affecting the reliability of the indicators - stress, excitement, physical stress, fatigue and t.
No less important factor influencing the accuracy of measurements is the correct choice of a device for monitoring pressure - a tonometer. At present, consumers are offered a wide range of devices, differing in their design features and degree of automation of the measurement process. In this article you will find recommendations that will help make the best choice of a tonometer.
Types of tonometers The determination of pressure using portable devices - tonometers (sphygmomanometers) is carried out using two methods - oscillometric and listening to Korotkov's tones. Both methods use a cuff in which an overpressure is created. In the first case, it is located on the finger, wrist or shoulder, and in the second - only on the shoulder. There are the following types of tonometers:.
• Mechanical tonometer. Apparatus for measuring pressure by method H. Korotkova. In this case, the participation of a person at all stages. The accuracy of measurements depends on the experience measuring, the state of the hearing aid. The device consists of a cuff, a pear to create pressure in the cuff and a manometer.
• Semi-automatic tonometer. The measurement principle is based on the oscillometric method. The most accurate results allow you to get devices with a cuff that is located on the shoulder. All stages of measurement, except for air injection into the cuff, are performed without human intervention, and the results of measurements can be seen on the LCD display. In addition to the pressure indicators, the device provides data on the heart rate, determines the arrhythmia, stores the measurement values ??in memory.
• Automatic tonometer. Electronic device for measuring pressure, fully automating the measurement process. All steps are carried out and monitored by a tonometer, and the results can be observed on the LCD display.
Which tonometer to choose?.
The most reliable results are obtained with the help of tonometers, the cuff of which is fixed on the forearm. They will suit users of any age and with any state of health. Semi-automatic and automatic models - this is the only right choice for impaired people, as well as patients with hearing impairments.
A great advantage of modern models of tonometers is the availability of additional functions, for example, such as determining the pulse rate, the arrhythmia indicator, storing the indicators of the last measurements. An example is the tonometer dr. Frei (Dr. Fry) M-200A, providing an accurate and comfortable measurement in auto mode, equipped with an arrhythmia indicator, adjustable cuff and calculating the average for the last three measurements.
Carpal tonometers can be recommended to people who lead an active lifestyle. These are compact devices that you can take with you on long trips and carry out operational pressure control. The only restrictions for their use are diseases of the vascular system and age over 40, which is associated with a decrease in vascular elasticity.
A good example of a wrist blood pressure monitor is the Gamma (Gamma) M3-W, equipped with an adjustable cuff, automatic air discharge and bleeding, self-monitoring and other useful functions.
Where to buy a tonometer?.
A large assortment of original and high-quality tonometers is presented in the online store one-life. com. ua / tonometry, where you can order a device suitable for you according to parameters with fast delivery of goods to any region of Ukraine. The catalog contains a detailed description of the devices, information on how much is the device for measuring the pressure.
