Cardiac-based SpO2

Cardiac Based SpO2 White Board Animation

The methods for determining Nellcor pulse oximetry SpO2 values are founded on the fact that the patient’s true arterial oxygen saturation is associated with the patient’s cardiac-induced pulse. Nellcor focuses on the persistent and generally repetitive nature of these signals, since most patients exhibit a repetitive cardiac cycle.

Watch a demonstration of accurate and reliable monitoring during a simulated cardiac arrest. This simulation test was created to show that monitoring beat-to-beat behavior enhances patient safety by providing greater accuracy and reliability.

Clinical Solutions: Alarm Management

Covidien is the only company to receive FDA clearance for a motion-tolerant bedside pulse oximeter portfolio that is also compliant with ISO 80601-2-61 (International Organization for Standardization) standards for pulse oximetry. Nellcor™ SatSeconds Alarm Management: An estimated 85 percent to 99 percent of alarms in healthcare facilities don’t require clinical intervention.1,2 Because of this high percentage of insignificant alerts, clinicians can develop “alarm fatigue,” which can result in their tuning out these notifications and missing the alarms that truly signal a patient’s critical medical crisis. Monitor alarms are designed to alert caregivers to changes in a patient’s condition and can save lives. However, as the number of alarms encountered by clinicians on a daily basis rises, it has become difficult for caregivers to distinguish between clinically significant alarms and nuisance alarms. As a result, alarm fatigue has become a serious issue, which puts patients at risk. The SatSeconds feature analyzes desaturation events by multiplying their duration, in seconds, by the number of percentage points the patient's saturation drops below the SpO2 alarm limit. As a safety precaution, when three or more SpO2 alarm violations occur within 60 seconds, an alarm will sound even if the SatSeconds limit has not been reached.

United States CCHD Guidelines

CCHD guidelines recommend using motion-tolerant pulse oximeters

Nellcor™ pulse oximetry monitors are designed to meet your CCHD screening needs:

  • 1. Motion-tolerant pulse oximeter
  • 2. Reports functional oxygen saturation
  • 3. Has been validated in low perfusion conditions
  • 4. Has been cleared by the FDA for use in newborns
  • 5. Has an accuracy of ± 2%

Covidien is the only company to receive FDA clearance for a motion-tolerant bedside pulse oximeter portfolio that is also compliant with ISO 80601-2-61 (International Organization for Standardization) standards for pulse oximetry.

Get the Facts

A published study revealed an artifact in Masimo pulse oximeters, that increased saturation values of 87-90% by an additional 2%. In CCHD screening, an increase from 89% to 91% could mask some cases of CCHD, resulting in false negative screens with the Masimo pulse oximeters.1

What is the Digi-Cal Advantage?

Nellcor™ pulse oximetry with OxiMax™ technology is different from other pulse oximetry technology because we place the individual sensor's calibration curve in the sensor itself. Why does this matter? Because with an individual calibration curve placed in the sensor, Nellcor™ with OxiMax™ technology provides superior monitor and sensor performance. The Nellcor™ OxiMax™ technology monitoring system incorporates a small digital memory chip within every Nellcor™ OxiMax™ sensor. This technology enables the monitor to deliver accurate SpO2 and pulse rate readings even when confronted with challenging conditions such as patient motion combined with low perfusion.1

To take advantage of the latest Nellcor™ technology innovation, it is not always necessary to purchase new bedside monitors or multi-parameter monitor equipment.

New sensors and monitor enhancements can be added at any time.

Pre-Hospital Patients

Innovation in motion

When risk is highest, you need accuracy the most. In the pre-hospital/EMS environment, it can be helpful to have a small, lightweight, ergonomic pulse oximetry monitor that is reliable, even in difficult monitoring conditions.1 NellcorTM hand-held patient monitors incorporate patented NellcorTM digital signal processing technology to deliver accurate, reliable SpO2 and pulse rate values even during low perfusion and signal interference, including patient motion.2

Sensor Choice

NellcorTM pulse oximetry sensors are available in a wide array of options: reusable, adhesive and non-adhesive. Non-adhesive sensors can be used for neonates and patients with sensitive skin. When a patient is in respiratory distress and SpO2 is lower than 80%, accurate, real-time information is crucial. Used with NellcorTM pulse oximeters, the NellcorTM forehead SpO2 sensor may detect hypoxemic events faster than other sensors.2

NellcorTM non-adhesive sensors detect hypoxemic events 90 seconds faster1-3 and feature LoSatTM technology, providing an accuracy range of 60%-100%.4
