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.
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
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
The addition of pulse oximetry screening (POS - with new-generation, motion-tolerant technology) to existing screening methods such as antenatal ultrasound and postnatal examination increases the overall detection of CCHD to 90-96%, irrespective of the detection rates of the other screening methods.6,7,8
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.9
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).10
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.12,13
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.14 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.
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.15
In fact, respiratory compromise — incidents of respiratory insufficiency, failure and arrest — is an avoidable patient safety issue.16 A 2016 analysis of 44,551 acute respiratory events revealed a mortality rate of 39.4%.17
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.
