Types of tonometers and peculiarities of their use

The monitor is a medical device used for the regular monitoring of blood pressure. Models suitable for home use, available in two versions: electronic and mechanical.

Mechanical tonometers

Appeared much earlier email. It is believed that these models focus more on the use of medical professionals, but many people use them at home. Positive reviews about the mechanical tonometers type indicate that they are less dependent on external influences. This makes the process of measuring the blood pressure is more informative. The price is also affordable for most consumers.

Among the significant deficiencies noted the following:

- mandatory use of the stethoscope,

- great physical effort to inflate the cuff,

is a relatively complex operation, because the accuracy of measurements depends on auditory data (the patient is hard of hearing it is difficult to accurately determine the first pulse kick).

Electronic sphygmomanometer

The most suitable option for use by patients at home. Automatic sphygmomanometer assume inflate without any effort, because all it takes is one push of a button. They are available with two types of cuffs - shoulder and wrist. Shoulder cuff securely fixed, so the probability of error in blood pressure measurement significantly lower. Models with carpal cuff perfect for lovers of active leisure. During the trip or holiday in the fresh air just put on wrist cuff. An important disadvantage of this type of tonometer is a high percentage of error and the probability of obtaining inaccurate data in people with severe atherosclerosis of the vessels. Semi-automatic blood pressure monitors require the use pear for air injection.

The advantages of an electronic sphygmomanometer: operation requires no special skill, high accurate and fast determination of the arterial pressure, it is possible to know the pulse and to detect the presence of arrhythmia (more precisely, arrythmia). Readings electronic sphygmomanometer can be written to the memory device and to compare performance on subsequent measurements. Among the negative aspects distinguish the probable inaccuracy of blood pressure in people suffering from severe forms of arrhythmia. Although this situation also has out - produced electronic models specifically designed for patients with arrhythmia.
