Accurate and Dependable SpO2 Readings Start with PureLight® Sensors.
PureLight sensors produce a high-intensity pure light spectrum which eliminates variations in readings from patient-to-patient and sensor-to-sensor.
The PureLight Principle
Red and infrared light sources (LEDs) are essential to pulse oximetry sensors.
- The red LED measures deoxygenated hemoglobin
- The infrared LED measures oxygenated hemoglobin
Common red LEDs may produce a secondary spectrum emission (contamination)
- Contamination impacts the oxygenated hemoglobin measurement
- LED contamination affects an oximeter's calibration curve resulting in inaccurate SpO2 readings below 80%
PureLight red LEDs only produce the pure light spectrum
- PureLight LEDs do not cause a shift in the oximeter's calibration curve at SpO2 levels below 80%
- Nonin PureLight sensors eliminate variations in readings from patient to patient and sensor to sensor
