What is a blood pressure monitor? How many types are there? Notes on use and storage

A sphygmomanometer is a medical device used to measure the rise and fall of a user’s blood pressure. So what parts does this tool include and how many types are there? Find out with Tnhelearning.edu.vn right in the article below!

What is a blood pressure monitor?

A sphygmomanometer is an instrument that measures the rise and fall of blood pressure over a certain period of time. The machine consists of a screen (for electronic machines), a meter and a pump (for a mechanical machine), a cuff. Blood pressure will be measured by oscillation, then using an analysis algorithm to put the reading on the screen.

With the indicators clearly displayed on the screen, people can monitor their own health status. From there, you can map out a suitable diet and rest, have a reasonable exercise plan to improve and prevent dangerous diseases.

How many types of blood pressure monitors are there?

Blood pressure monitor

Blood pressure monitor is a traditional measuring device used in many hospitals and clinics. Because this is one of the difficult machines to use, it needs someone with professional experience to know how to use it correctly and read the measurement results correctly.

The mechanical sphygmomanometer consists of an inflatable balloon, a cuff wrapped on the upper arm, and a sphygmomanometer. The device has high durability and the measurement results are not much different. Therefore, the machine is often used by nurses and doctors to check the health status of patients.

Electronic blood pressure monitor

Electronic sphygmomanometer belongs to the next generation compared to mechanical sphygmomanometer, whose operating mechanism depends on electrical sensors and battery power. Measurement results will be automatically displayed as numbers on the electronic screen and users can easily monitor their health status.

In addition, the device also has a compact design, easy to carry with you when traveling or away from home. Moreover, this type of machine is very easy to use, anyone can measure it by themselves without the need for expertise or with the help of a doctor.

Mercury sphygmomanometer

The mercury sphygmomanometer has a gravity-based mechanism of action. The device is durable, easy to use, and has little chance of failure or error. This type is considered by many experts as a machine that can produce accurate measurement results quite high compared to other types of blood pressure monitors.

Mercury sphygmomanometers are relatively heavy, difficult to move, and difficult to use. Therefore, this type of machine is usually fixed at the clinic, the patient will be checked for blood pressure by qualified medical doctors.

Notes on using a blood pressure monitor

In the process of using a blood pressure monitor, you should note the following points to ensure accurate measurement results and prolong the life of the device:

For machines using AC adapter:

• It is recommended that you use an original AC adapter specifically designed for the machine.
• When your hands are wet, do not plug in or unplug from the outlet.
• If the equipment or wires are damaged, you should not repair it yourself at home, but need to take it to a reputable repair place.

• Be careful not to install the wrong battery terminals.
• It is recommended to use the original battery of the device.

In addition to the two issues mentioned above, you need to be careful with the following issues:

• You must not use a blood pressure monitor while in a car.
• You must not disassemble the machine or the cuff.
• At the cuff, you must not inflate more than 299 Hg.
• Do not place the meter near mobile phones, computers or devices that emit electromagnetic fields, because it will cause the device to work incorrectly, and the measurement results will not be accurate.
• Use the machine in accordance with the manufacturer’s instructions on measuring posture, how to wrap the cuff, measuring position, how to read measurement results, how to set parameters and use the machine’s modes to ensure limitations. measurement error.
• It is recommended to clean the machine periodically every 2-3 months , avoiding dust and dirt from affecting the details and operation of the machine.
• During the cleaning process, it is necessary to use a soft, dry cloth to wipe the machine, absolutely do not wipe with a wet cloth or use detergents, cleaning solutions, volatile solutions.
• Store the machine in a dry place, avoid direct sunlight, avoid high temperature, high humidity.
• Do not allow the device to be dropped, subject to strong impact or spill liquids on the device.
