Seven Reasons to Consider Nellcor™ Pulse Oximetry

Seven Key Intended Benefits of Nellcor Pulse Oximetry Technology

So, you want to learn more about the key differentiators that will help determine which pulse oximetry technology to choose, but you aren’t sure what the differences are between the brands available and which brand will suit your needs. We have outlined some information about our Nellcor™ pulse oximetry technology to help you compare our brand to others. Here are some key components of Nellcor™ pulse oximetry technology to consider:

Accuracy and Motion

Nellcor™ pulse oximetry technology is engineered with cardiac-based digital signal processing, and this has given us low saturation accuracy specifications between the measurement range of 60 - 80 percent, with an accuracy of +/- 3 digits.1

Nellcor™ pulse oximetry sensors with OxiMax™ technology are validated for use between the SpO2 measurement range of 70-100 percent with an accuracy of  +/- 2 digits.2

Nellcor™ pulse oximetry with OxiMax™ technology meets standards for motion tolerance  and is also compliant with ISO 80601-2-61.3

Nellcor™ Pulse Oximetry Technology:  A Cardiac-Based Solution

Our methods for determining SpO2 values are founded on the fact that the patient’s true arterial oxygen saturation is associated with the patient’s cardiac-induced pulse. It focuses on the persistent and generally repetitive nature of these signals to determine SpO2.

Digi-Cal Advantage

Nellcor™ pulse oximetry with OxiMax™ technology works by incorporating a small digital memory chip within every sensor.  The calibration curve is placed in the sensor itself and does not rely on preprogrammed data housed in the host monitor to calculate SpO2.  This means the monitor is engineered to deliver accurate SpO2 and pulse rate readings even when confronted with challenging conditions such as patient motion and low perfusion.4 

Critical Congenital Heart Disease (CCHD) Screening

With a +/-2 neonatal accuracy, Nellcor™  pulse oximetry technology meets the criteria established by Alex R. Kemper, MD, MPH, MS in the Strategies for Implementing Screening for Critical Congenital Heart Disease recommendations published in the American Academy of Pediatrics Journal in 2011.5

These recommendations state that CCHD screening is performed using a pulse oximeter FDA-cleared for use with newborns, has been validated for low-perfusion conditions, is motion tolerant and has an accuracy of two percent root-mean-square accuracy.5

It is estimated that the cost of pulse oximetry CCHD screening is between $10–$15 per infant.  When considering conservative estimates of potentially averted adverse events and extended hospital stays, an economic analysis calculated that CCHD screening appears cost-effective relative to other services.6

Alarm Management

Nellcor™ SatSeconds alarm management technology is engineered to support hospitals in addressing the Joint Commission 2019 National Patient Safety Goal for alarm safety in hospitals (NPSG 06.01.01).7

  • Nellcor™ Sat Seconds Alarm Management. Proven to reduce nuisance alarms for all patients and by 40 percent with a setting of 50 for neonates.8 The technology is engineered to:
  • Calculate the duration of the event, multiplied by the number of percentage points that SpO2 falls outside of the saturation alarm threshold.
  • o Provide range of alarm settings – 10, 25, 50, or 100 minutes so changes to the settings can be made depending on the clinical environment and patient condition.
  • Nellcor™ Saturation Pattern Detection (SPD) Alert. This alert is designed to detect patterns of desaturation that may be indicative of repetitive reductions in airflow.
  • The alert uses a triangle icon that when “full” triggers an alarm to alert staff about these worrisome patterns. It can provide staff with information that helps to balance pain medication and airway safety and can alert staff to investigate situations they may not otherwise have known about.

Respiration Rate

Nellcor™ respiration rate technology provides a continuous assessment of oxygenation and respiration rate trends through a single finger sensor. This technology may also provide an early warning of impending respiratory distress — to help you intervene early.9,10

A single sensor can be used to measure SpO2, pulse rate and respiration rate, eliminating the need for additional sensors such as those used for acoustic measurement of respiratory rate.

The  software calculates respiration rate with an accuracy of +/- 1 breath per minute relative to a capnography-based reference.11   It uses pulse oximetry technology, sensors, and workflows to derive respiration rate based on the changes in the photoplehysmogram (pleth) waveform that occurs as a result of breathing. Breathing causes changes in the cardiovascular, respiratory, and autonomic nervous systems and results in changes in the pleth waveform. These modulations can be used to calculate respiration rate.

Nellcor™ respiration rate software is engineered to complement pulse oximetry, pulse rate and the Nellcor™ saturation pattern detection alert (SPD) to help provide a more complete picture of a patient’s respiratory status.

Expanding Your Monitoring Platforms

Should you rely on monitoring SpO2 alone to provide the best care for your patients? Continuous monitoring of both oxygenation and ventilation are two key factors to help reduce respiratory compromise early enough to identify the problem and provide intervention.12

In fact, respiratory compromise — incidents of respiratory insufficiency, failure and arrest — is an avoidable patient safety issue.13 A 2016 analysis of 44,551 acute respiratory events revealed a mortality rate of 39.4%.14

This is why we offer a portfolio of respiratory monitoring solutions including pulse oximetry, capnography and remote monitoring technology that work in harmony to help you focus on what you do best: help save lives.
