Fingertip Pulse Oximeter

Components of a fingertip pulse oximeter: A microprocessor, EPROM and RAM, two digital-to-analog converters to control the LED, a device to filter and amplify the signal received by the photodiode, and an Analog-to-digital converter to digitize the received signal for the microprocessor. The LED and the photodiode are placed in a small probe in contact with the patient’s fingertip. Pulse Ox, small liquid crystal display.

Knowledge about Finger Pulse Oximeter

Working principle of finger pulse oximeter: Based on the absorption spectrum of reduced hemoglobin and oxygenated hemoglobin in red and near Red Light, the empirical formula of data processing is established by Lambert-Beer Law. The use of photoelectric oxygen detection technology combined with volume pulse recording technology, two different wavelengths of light (660nm red light and 905NM near-infrared light) was used to illuminate the fingernail tip of the human body through a penetrating fingernail sensor after the information is processed by electronic circuit and microprocessor, the measured results are displayed by two groups of LED.


Usage of Finger Pulse Oximeter

The coronary disease can cause a drop in blood oxygen levels, which can occur even in asymptomatic patients, or in people who do not feel unwell. However, this lack of oxygen could be an invisible killer. The oximeter helps check oxygen levels in the blood and can also monitor asthma, heart, lung, and other respiratory diseases. If the body is experiencing hypoxia, it will damage the body’s vital organs, so blood oxygen levels should be monitored regularly.
