Pulse oximetry sensors use red and infrared LEDs to measure deoxygenated and oxygenated hemoglobin. LED contamination can affect the oximeter calibration, resulting in inaccurate SpO2readings below 80%. Nonin sensors use PureLight LEDs, which produce a high-intensity pure light spectrum that consistently...
What is SpO2? (Pulse Oximetry) There has been a surge in public awareness regarding pulse oximetry, also known as SpO2. Some doctors are now advising their COVID-19 patients to monitor their SpO2 levels at home. As a result, many individuals are curious about SpO2 for the first time. If...
Pulse oximetry is based on the principle that oxygenated blood and deoxygenated blood (blood with a reduced concentration of oxygen) absorb red and infrared light differently. Oxygen-rich blood absorbs more infrared light, while oxygen-poor blood absorbs more red light. By measuring how much of ea...
