PureLight Sensor from Nonin

PureLight Sensor Technology

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 shifts the 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.

Accurate and dependable SpO₂ readings start with PureLight sensors.
