People suffering from cardiovascular disease should constantly monitor changes in blood pressure. This indicator can be measured using special measuring instruments that manufacturers produce in different variations. The manual tonometer differs from analogs in the compact sizes. The medical device is convenient to use. You can take it with you to work, to the country, on a trip or a business trip.
Manual blood pressure monitor: the principle of operation of the device
The medical device is used to determine blood pressure. With its help, an indicator is measured that determines how blood presses on the vascular walls. The volume of blood in the human circulatory system, which the heart is able to pump over a certain time, and the resistance force from the vascular system are being studied.
The upper or systolic value indicates the force with which blood acts on the arteries during its ejection from the heart. Lower or diastolic value -this is an indicator that displays the strength of the influence of blood on the walls of blood vessels at a time when the heart muscle relaxes. A good device should measure both indicators correctly. It is for these purposes that such a tonometer is used.
To measure the pressure of a person suffering from arrhythmia, special devices are used. They are equipped with modern technologies that allow you to display the correct readings. Intelligent systems allow to eliminate errors during the blood pressure examination procedure. Movement indicators help you secure the cuff on your arm.
Who is this portable device intended for
The first models were only suitable for people under 40, provided that their blood vessels were he althy. After the indicated age limit, signs of atherosclerosis appear. The vascular walls become harder, the wrist device does not always display the readings correctly: it does not recognize a weak signal.
The modern hand-held blood pressure monitor, which is installed on the wrist, has been greatly improved. The latest models have a cuff with a special shape that allows you to read pulse tones simultaneously from two arteries. This design makes it possible to obtain more accurate measurements.
Features of choosing a portable blood pressure monitor
For the elderly, children, athletes or pregnant women, they produce devices with advanced functionality. Thanks to the presenceadditional options, pressure readings are displayed more accurately.
- Hand-held wrist blood pressure monitor for the elderly is the best solution when a person has to measure blood pressure himself. When using an automatic device, no physical effort is required. If a person has impaired vision, then a device with large numbers is suitable for him. They also sell meters with sound that even the blind can use.
- Children are not suitable for regular adult meters. They require a handheld blood pressure monitor with a small cuff. It is selected around the circumference of the arm - for newborns - from 5 to 7.5 cm; for babies from 7.5 to 13 cm; for children - from 13 to 20 cm. For kids, manufacturers produce blood pressure monitors with bright colors and funny patterns. They resemble toys, which attract the attention of the child.
- Athletes should carefully monitor their he alth. Using a blood pressure meter allows you to be sure that increased loads during training are safe for the human body. Experts recommend that athletes use both mechanical and automatic blood pressure monitors. The values obtained are as accurate as possible. During the procedure, a manual blood pressure monitor is worn on the wrist, and a mechanical blood pressure monitor is worn on the shoulder.
- In the body of a pregnant woman, hormonal changes occur, significant changes are observed in the work of all vital systems. Pressure surges may indicate problems in the heartvascular system. Electronic models automatically process the indicators that appear on the display. Meters with a minimum error of no more than 3 mm Hg are suitable for pregnant women. st.
Manual blood pressure monitor on the wrist: how to use the device yourself
The device is easy to use, no problems should arise during the examination procedure. A person must fasten the device on his wrist and press the start button. The hand should be at the level of the heart. The results are shown on the display after a few seconds. The hand should be relaxed. You cannot talk or move during the procedure. Measurement should be done 2 or 3 times. An indicator of blood pressure is the average value. It is better to write down the obtained values so that it is convenient to calculate.
How to choose your own device
Today blood pressure monitors are sold everywhere. They can be bought at a pharmacy or ordered online. When choosing a device, you can be guided by the following criteria:
- functionality and focus;
- warranty period;
- cuff length;
- error of indicators obtained during measurement;
- cost of the device.
When you need to conduct research away from home, choose a model that runs on rechargeable batteries. It is also recommended to get the opinion of those who have already bought a manual blood pressure monitor on the wrist. User reviews allow you to evaluate all the advantages and disadvantages of each model. As a rule, the most popular devices are considered the highest quality.
Popular blood pressure monitors on the wrist from the Japanese brand Citizen
The device inflates the cuff automatically. The device is equipped with a large LCD display. The memory of the device is designed for 7 measurements.
The meter allows you to measure blood pressure with pulse rate. The error in measuring the pulse is 5%, and when measuring blood pressure 4 mm Hg. Art. There is an option for automatic shutdown and the ability to connect the device to an additional power supply. Citizen wrist blood pressure monitor can simultaneously display both blood pressure and pulse measurements.
Reviews of other models
In addition to the Citizen blood pressure monitor, there are many positive reviews about one more blood pressure monitor. The Omron meter is a device with excellent technical characteristics. The device allows you to measure systolic and diastolic pressure and pulse rate. It has a memory for 60 values. Errors are allowed when measuring pressure by 3 mm Hg, and when measuring the pulse - by 5%. Powered by 4 x 1.5V AAA batteries with AC adapter.
Modern blood pressure monitors show accurate measurement results. If you use a mechanical device for self-measurement, then the errors will be greater than those indicated on the best models.automatic devices. A person has to inflate the cuff himself, and this leads to muscle tension and an increase in blood pressure. More accurate values are shown by automatic devices when the procedure is carried out independently.
