Fingertip Pulse Oximeter

The pulse oximeter uses a cold light source that shines a light through the fingertip, making the tip appear to be red. By analyzing the light from the light source that passes through the finger, the device is able to determine the percentage of oxygen in the red blood cell.
Basically, pulse oximetry is a painless, noninvasive method of measuring the saturation of oxygen in a person’s blood. Oxygen saturation is a crucial measure of how well the lungs are working. When we breathe in air, our lungs transmit oxygen into tiny blood vessels called capillaries.
The Pulse Oximeter is a non-invasive device intended for checking oxygen saturation of arterial hemoglobin (SpO2) and the pulse rate of adults at home.Pulse oximeter measures and displays real-time pulse and SpO2 level. Pulse Oximeters are available fingertip and other formats with a variety of functions.Accurate and reliable – Adopts advanced technology and approved by FDA&CE, this pulse oximeter accurately determine your SpO2 and pulse rate in 5 seconds ..
Pulse oximetry is a test used to measure the oxygen level (oxygen saturation) of the blood. It’s an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs. A clip-like device called a probe is placed on a body part, such as a finger or ear lobe.
The principle of pulse oximetry: Pulse oximetry uses spectrophotometry to determine the proportion of hemoglobin that is saturated with oxygen (ie, oxygenated hemoglobin; oxyhemoglobin) in peripheral arterial blood. Light at two separate wavelengths illuminates oxygenated and deoxygenated hemoglobin in blood.
