Pulse oximeters

Pulse oximeter is an electronic saturation device, which is designed for rapid measurement of oxygen in the blood. The user receives the result within a few seconds. Information about the measurements is displayed on the screen. In some models, an additional audible signal is provided, which indicates the completion of the test. 

Pulse oximeter: principle of operation

Pulse oximeter on the finger works with the help of photosensors that translucent tissues, by the volume of peripheral vessels and the level of absorption of infrared light determines how many hemoglobin molecules are bound to oxygen. Hemoglobin that binds to oxygen molecules is transformed into oxyhemoglobin, a substance that absorbs infrared light. 

An LED placed in the body emits infrared rays that are partially absorbed by living tissue. Photo sensors transmit data to the microprocessor, which analyzes the information and visualizes the result on the display. The advantage of using the device is non-invasive examination. The test does not require violation of the integrity of the skin. Measurements are carried out in medical institutions and at home. 

Pulse oximeters: types

To measure oxygen in the blood, different models are used, which differ in the place of contact of the device with the body. The main types are:

• - Finger. To determine the concentration of oxygen, the user inserts a finger into a special opening.
• - Carpal. To perform the test, the device for measuring oxygen in the blood is put on the wrist. 
• - Breast-worn. Devices are designed to be worn on the chest to constantly monitor oxygen readings. 

To get comprehensive information about the current state of the body, it is worth buying a device for measuring saturation, which is worn on the wrist. In addition to information on oxygen concentration, the user receives data on cardiac activity - pulse, heart rate, blood pressure readings. 

Measurement of saturation is necessary in the treatment of many diseases, including coronavirus infection, pneumonia, bronchitis and other lung pathologies. To constantly monitor the condition of patients, you need to buy a product for measuring oxygen in the blood. When choosing a device, take into account the size and convenience of use. The oxygenometer on the finger is characterized by compact dimensions. The length and width of the device do not exceed 8 cm and 6 cm, respectively. The pulse oximeter fits freely in a pocket or bag - it is convenient to carry. Other selection criteria:

• - Accuracy of measurements. The error should not exceed 3%. 
• - The range of measurements - within 70-100%. 
• - Versatility. Models with a spring mechanism are securely fixed on the finger of any diameter. 
• - Convenience of use. Large buttons allow people of any age to carry out measurements independently. The large screen clearly shows the results of measurements.
• - The period of autonomous work - up to 24 hours of continuous use. Usually batteries are used to keep the device operational. 

The price of a pulse oximeter depends on the design, manufacturer and functionality. Devices with additional functions - alarm, display backlighting, determination of perfusion index (PI), photoplethysmography (assessment of the state of blood vessels), are more expensive. The price of models with limited functionality is less.
