Nellcor™ Flexible SpO2 Sensor

Sold as Each

  • Soft rubber pulse oximetry sensor
  • Reusable
  • Designed for short-term (less than six hours) continuous monitoring for the majority of patients
  • Available in two sizes, large and small, for adult and pediatric patients weighing at least 20 kg (40 lbs.)
  • Features the pulse oximetry you trust- Nellcor™ SpO2 with OxiMax™ technology
  • Forward and backward compatible with your existing Nellcor™-compatible monitors
  • Engineered for dippable cleaning to enhance workflow efficiency  
  • Designed for short-term (<6 hours) continuous monitoring for the majority of your patients

Product Specifications

  • Length - Large and small, 925 mm, includes a connector and sensor housing
  • Patient weight ranges - The large and small sensors are intended for use on adult and pediatric (excluding infant and neonatal) patients weighing more than 20 kg

Indications for use  

  • Noninvasive continuous or spot-check monitoring of SpO2 and pulse rate
  • Indicated for use with monitoring systems that use Nellcor™ Oximax™ and Nellcor™ compatible pulse oximeters

Designed for dippable cleaning. That’s important because:

  • Probes can act as vectors of infection transmission
  • Meets the current home-care standard (IEC 60601-1-11:2015)
  • It also meets required operating conditions of: 
    • 0 to 40 C operating temperature
    • 15 to 95 percent non-condensing RH
    • 620 to 1060 hPa atmospheric pressure
  • Routine cleaning or low-level disinfection is recommended when using the sensor on the same patient


  • SpO2 accuracy* 70–100%: ≤2.5 digits (ARMS)
  • Pulse rate accuracy* 20–250 BPM: ±BPM

Validated by clinical tests, where the measured values of the sensors were compared with those of the arterial co-oximetry in healthy adult subjects over the specified functional oxygen saturation range.

These values were validated on the following monitors: Nellcor™ PM1000N, N600x, N560, N395.

Pulse rate accuracy was verified by simulated bench tests to ensure entire range was verified. These values were verified on the following monitors: Nellcor™ PM1000N, N600x, N560, N395.
