Pulsoksümeetrite

Pulsoksümeetrite, known in English as pulse oximeters, are non-invasive medical devices used to measure oxygen saturation in the blood and pulse rate. They work by shining red and infrared light through a translucent part of the body, typically a fingertip, earlobe, or toe. The device then analyzes how much of each light wavelength is absorbed by the blood. Oxygenated hemoglobin absorbs infrared light more than red light, while deoxygenated hemoglobin absorbs red light more than infrared light. By comparing the absorption of these two wavelengths, the pulse oximeter can estimate the percentage of hemoglobin that is saturated with oxygen, known as SpO2. Simultaneously, the device detects the pulsatile flow of blood, which allows it to calculate the pulse rate.

Pulse oximetry is a crucial tool in various healthcare settings, including hospitals, emergency rooms, and even for home monitoring. It provides valuable information about a patient's respiratory and circulatory status. Low oxygen saturation levels can indicate a range of conditions, such as pneumonia, asthma, chronic obstructive pulmonary disease (COPD), heart failure, or sleep apnea. The device is also widely used during anesthesia, surgery, and in intensive care units to monitor patients' vital signs. Its ease of use, portability, and ability to provide real-time data make it an indispensable part of modern medical diagnostics and patient care.
