Pulse-meter on finger: characteristics and function overview
Pulsemeters are now very popular not only among professional athletes, but also among ordinary people who monitor their health. In stores you can find many kinds of these devices. It is simple and convenient to use the heart rate monitor on the finger. Let's consider in more detail, in what cases this device will be useful and on what models it is necessary to pay attention.
What is a heart rate monitor?
People who lead an active lifestyle, it will be useful to learn about such a device as a heart rate monitor. A small device that allows you to constantly monitor the heart rate and the allowable rate of exercise. Such gadgets are almost always used by athletes engaged in athletics, swimming, cycling.
In medical practice devices of such purpose doctors strongly recommend to use people having any irregularities in the work of the heart muscle or the pathology of the vascular system. Such diseases are often found in old age and require constant monitoring of cardiac activity. The most convenient in this case is the pulse meter on the finger. In Moscow and any other major cities, the device can be purchased at sports stores or at points of sale of medical equipment.
Types of heart rate monitor
Modern models of heart rate monitor are divided into two types: wired and wireless. More convenient to use, of course, those devices, the signal from which is transmitted over a radio channel in digital or analog mode. Devices can be worn on clothes, wrists or a finger, fastened to the rudder of a bicycle( simulator).
By type of sensor design, the heart rate monitor is divided into:
- devices with a built-in sensor;
- devices, the sensor of which is put on the ear or finger;
- devices with a chest sensor( considered the most accurate).
Principle of operation
The finger pulse meter and other similar devices operate on the principle of a cardiograph. The sensor on the device records the signals that occur when the heart muscle contraction. Then the received data enter the device itself, which processes them and displays the result on the display. The values received for a day can be stored in the device for some time. If necessary, they can be shown to the doctor or coach.
When should I use?
People with heart problems should use the heart rate monitor on their finger on an ongoing basis. Especially without them can not do during the increased physical exertion - a long walk, cleaning in the house."Mini-doctor" in a timely manner will inform you about the need to take a break and rest. It should be borne in mind that the heart rate monitor does not replace other devices that allow monitoring the patient's condition.
Functions of the heart rate monitor
Each device model has a number of useful functions. A medical pulse meter must necessarily record data on cardiac contractions. And on the majority of devices there is an opportunity to enter boundary maximum and minimum values of pulse rate. In the event that the heart rate has reached these values, the device will notify the host about it by means of a beep.
In modern gadgets, it is possible to plot graphics and tables based on monitoring data. This will help the specialist to see how the patient's heart rate changes throughout the day, and to assign additional studies.
Different kinds of finger pulse meters have one more useful function - calorie counting. This allows you to choose the necessary physical load."Advanced" heart rate monitors are able to transmit data via wi-fi( or bluetooth) to a personal computer, a smartphone.
Devices that athletes use must preserve the history of training, warn of the need to reduce or increase the tempo, display speed( and sometimes height), create individual training, show average heart rate and lap time. In addition, almost every heart rate monitor has the functions of a clock, an alarm clock and a stopwatch.
How to choose a heart rate monitor for a finger?
A photo and review of some popular models of finger pulse meters will be presented below. Heart rate meters of this kind have a number of advantages over others. Due to the absence of wires, they do not constrain movements. It should be borne in mind that analog instruments can give inaccurate readings if a person with the same device is next. The more expensive models have a signal coding function that will avoid such situations.
The light weight and size of the pulse meters on the finger allow you to use them in any situation. A significant advantage is the protection against moisture. The body of some products for athletes is usually made of special waterproof materials that allow using the heart rate monitor even in bad weather conditions. Waterproof heart rate monitors are designed for swimmers. Conventional medical products generally do not have such functions and are made of durable plastic.
When choosing such a gadget, it is necessary to pay attention to what purpose it will be used and what minimum set of functions it should have. This directly affects the cost of the device.
Heart Rate Monitor ID-501-FC
The device helps to measure the heart rate. A fairly simple device that does not have additional functions, but at the same time is in demand among consumers due to its low cost. The price of the heart rate monitor is 750-1200 rubles.
The case of the product is made of plastic and looks like a ring. The display is not touch, it shows only the frequency of heart beats( the error is not more than 10).You can use the device for both sports and medical purposes. The finger pulse meter ID-501-FC is made in Taiwan and has a small warranty period of operation - only 1 month. Reviews also say that with proper operation the gadget can last much longer.
Pulse Plus ID-503
The model is similar in appearance to the appearance - the device is made in the form of a ring, which is put on the finger. It allows you to accurately measure the pulse both during training and in a relaxed state. The pulse meter on the finger of this model is patented in many countries. The cost of the device is 3500-4300 rubles.
Miniature product allows you to enter personal data, determine the temperature of the environment, count the number of heartbeats and calories lost, calculate the integral load for one workout. The pulse meter shows the average pulse and reports a low battery charge.
Oximeter - what kind of device?
Controlling the oxygen level in the blood and monitoring the work of the heart muscle in the blood allows a device such as a pulse oximeter. On the finger the device is put on the type of clothespins. It consists of two parts, which are connected together and reinforced with a spring. The inner working surface is made of rubber to prevent slipping.
Pulse oximeters are equipped with a display, which displays all the necessary data. They can be used both for single use and for continuous monitoring of saturation and cardiac contractions. The device allows you to quickly get the result of measurements, which greatly facilitates the task in the process of diagnosing the patient.
The highly informative method of investigation makes it possible to evaluate the work of the respiratory system and to recognize in due time the lack of oxygen. Pulse oximeters are used in anesthesiology, with diseases of the lungs and bronchi. It is recommended to use the device for people who have professional pathologies of the respiratory system, low hemoglobin level.
Finger pulse meter: reviews
Gadgets that provide information on the number of heartbeats and oxygenation of the blood, are very popular not only among athletes. Feedback from ordinary people suggests that with such simple-to-use appliances, you can constantly monitor your health and properly distribute physical activity. The finger pulse meter is often used as an express diagnostic.
The cost of the device depends on the country of manufacture and functionality. The most accessible are the Chinese heart rate monitor, allowing only to measure the heart rate. Modern models are equipped with many additional functions: large built-in memory, communication with PC, calorie counter, compass, thermometer, barometer, load distributor, coded sensor, GPS-navigator.
