Portable heart rate monitor oximeter on the finger Pulse Oximeter LK87

Description

Pulse Oximeter LK87 is a modern control and diagnostic medical device. It is designed to measure the saturation of arterial capillary blood with oxygen. This indicator is one of the most important in the human cardiovascular system. After all, the lungs fill and saturate arterial blood with oxygen. Lack of oxygen is dangerous, and there are a number of diseases in which monitoring this indicator is important, as well as the accuracy of the readings. Lack of oxygen (hypoxia) complicates the treatment of diseases.

The easy-to-use pulse oximeter-oximeter (created by specialists in the field of medicine and computer technology) is an indispensable device for everyone today. It can be used for both single measurements and for long-term monitoring (continuous control) of oxygen levels and heart rate. For the study, it is not necessary to take blood from the arteries, as it was done before.

An individual pulse oximeter can be recommended for everyone. It is also mandatory for people undergoing oxygen therapy. In this case, a medical heart rate monitor on the finger will ensure the greatest effectiveness of treatment by measuring and monitoring the necessary indicators. One of the main advantages of a heart rate oximeter is its availability, high accuracy of readings, simplicity and mobility. After all, you can take it with you, thanks to its light weight and size. Some models come with a case and a strap for greater convenience. High quality plastic and ergonomic design are durable enough to withstand carrying, light bumps and falls. The pulse oximeter is also not sensitive to external factors such as humidity and temperature, but you should study the instructions to find out in which range the readings are most accurate. All this allows it to be used in emergency medicine.

The principle of operation of the Pulse Oximeter LK87.

It has a peripheral sensor, a microprocessor and a display that shows information (in advanced models, the pulse curve), its frequency and the level of oxygen in the blood (saturation). Almost all devices are equipped with an audible alarm. The sensor, equipped with two LEDs, is most often applied to the finger, but also to the earlobe or nose wing.

The light from the sensor diode, which passes through the tissue capillaries to the photodetector, is partially absorbed by soft tissue and blood. The degree of absorption depends on how much hemoglobin is saturated with oxygen. The photodetector registers changes in blood color depending on this indicator. The data obtained is shown on the display: the oxygen level is displayed in 5-15 seconds. The pulse rate is calculated depending on the number of LED signal cycles per unit of time.

The most important condition for the reliability of the accuracy of the data obtained is complete immobility of the finger during the measurement process.

The norms of saturation, oxygen saturation in the blood are 95-98%. The research method used in the pulse oximeter is highly accurate. It also helps to assess the functions of the respiratory system, recognizes respiratory failure, in which the oxygen level falls below 95%. It is used professionally by anesthesiologists in surgery, as well as in chronic obstructive pulmonary disease, sarcoidosis, tuberculosis, and occupational lung diseases (caused by production and enterprises).

It is very easy to use. But when working with it, you need to remember a few simple rules, which will allow you to get accurate data:

Before using the pulse oximeter, check the battery level. If the battery level is low, you need to charge it; most models have a charge indicator.

Wait a few seconds after turning on the pulse oximeter, it will complete the self-test and be ready for measurement;

The sensor should be attached to the finger in such a way that it is securely fixed and there is no excessive pressure;

The nail of the finger selected for the test should be clean and free of nail polish, as its presence distorts the results.

After waiting 5 to 15 seconds, the pulse oximeter will display the saturation and pulse data. The readings are readable and clear, and in some models with an OLED display, you can choose the format of the information displayed, as well as the position.

In rare cases, a pulse oximeter can make mistakes, just like any other electronic device. This can be indicated by rapidly changing saturation and pulse rates over a wide range. For example, 96% suddenly changes to 82%, which is not physiologically possible. Repeat the measurement according to the paragraphs.

In case of doubts about the reliability of the data obtained with the pulse oximeter, the readings can be compared with stationary medical devices in clinics and hospitals.
