Accurate readings with PureLight technology

Nonin Medical has designed the PureLight reusable sensors for patients of all sizes and clinical presentations. The reusable sensors are ideal for short-term monitoring, stress testing, spot checks or any situation where the risk of cross-contamination is low. A comfortable sensor, each is designed for a specific application and is form-fitted to decrease ambient light interference.
 
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
