Nellcor™ Technology

When used with Nellcor™ pulse oximeters, Nellcor™ SpO2 adhesive sensors that feature LoSat technology help ensure accuracy in challenging conditions.

This offers clinicians:

  • Accurate SpO2 tracking in low saturation conditions: 60%-80% SpO21
  • Improved oxygenation assessment for patients with challenging conditions

Sensor First: Effective SpO2 Sensor Application

It is important to apply the sensor to the patient first to speed response time to post accurate data. Applying the sensor first can help reduce the monitor response to motion, light, or electrical interference.([FOOTNOTE=Saraswat A, Simionato LK, Dawson JA, Thio M, Kamlin O, Owen L, et al.

  • **Accuracy specifications are as published by Masimo and Nellcor™ Puritan Bennett LLC. All accuracy specifications are ± 1 SD. (Pulse oximeter measurements are statistically distributed; about two-thirds of pulse oximeter measurements can be expected to fall in this accuracy [ARMS] range.) See product instructions for detailed information.

  • ‡ Per Masimo’s Directions for Use, there are no accuracy claims below the 70% to 100% range for SpO2 for any sensors when used with Masimo SET monitors, except for the LNOP Blue sensor. For its Rainbow SET monitors used with Rainbow sensors, Masimo’s published specifications are ± 3 digits (± 1 SD) accuracy in the 60% to 80% range for patients > 3 kg.
