Congenital heart disease (CHD) is defined as a structural abnormality of the heart that is present at birth, which impacts proper and/or optimal blood flow.
More specifically, critical congenital heart disease (CCHD) is a subset of lesions commonly defined as “any potentially life-threatening, duct-dependent heart lesion from which infants either die or require invasive procedures (surgery or cardiac catheterization) in the first 28 days of life,2” although some publications like the CDC extend the definition to include the first year of life.3

It has been shown that pulse oximetry can be cost-effective as a noninvasive method for improving early diagnosis rates of CCHD, especially in low-resource areas. 1 10-12
According to a model-based cost effectiveness analysis comparing pulse oximetry screening to no pulse oximetry screening from the Ontario healthcare payer perspective, pulse oximetry screening yielded an incremental cost effectiveness ratio of CAD$1,110.79 per quality-adjusted life months. This was well below the predetermined threshold of CAD$4,166.67. 8†
According to a prospective analysis of costs and cost effectiveness of pulse oximetry screening on 100,000 newborns in the Dutch perinatal care setting. Pulse oximetry screening yielded an incremental cost-effectiveness ratio of €139,000 per additional newborn with CCHD. There was a willingness to pay threshold placed at €20,000 per gained quality adjusted life year.9‡
Neonates with an abnormal pulse oximetry screening are 5.5 times more likely to have CCHD compared to those with a normal screening.13 Additionally, late diagnosis of CCHD is associated with higher rates of hospital admissions and inpatient costs during the first year of life.18 According to a retrospective assessment of states that mandated universal pulse oximetry, there was a 33% decline in early infant CCHD related events after the mandate began.14
Despite the rise of antenatal detection over the years, there remains great variation in detection rates for this method based on location, technology, skill of technician, and screening protocol.1 4 15 16 Even in settings with high antenatal detection, pulse oximetry screening can be beneficial in identifying previously undiagnosed patients with CCHD.7 12 17 18
False-positive cases of pulse oximetry screening have been noted to require medical intervention for non-CCHD related conditions and may be important secondary targets of pulse oximetry screening, especially in low-resource settings.5 10 11 19
Pulse oximetry screening in the NICU is feasible and can be effective at detecting unrecognized CCHD in neonates.20-22
There are several recommendations for screening practices and protocols for CCHD, with numerous protocols used across studies. The main factors for screening, which are influenced by local needs and limitations, include:
The type of CCHD lesion influences pulse oximetry values and the sensitivity of pulse oximetry, with certain lesions being more detectable than others.18 24 28 29
Recommendations for pulse oximetry screening of CCHD advise measurements should be obtained using motion-tolerant sensors that can measure in low-perfusion settings.6 23 25 31 32 No specific pulse oximeter brand is mentioned in official recommendation statements for CCHD screening.
Nellcor™ Bedside Respiratory Patient Monitoring Systems meet all pulse oximeter criteria for CCHD screening outlined by the AAP guidelines (Figure 1) 25 as well as those put forth by the European Consensus Group23 and the Canadian Pediatric Cardiology Association.30
One recent clinical study showed that Nellcor™ pulse oximetry demonstrates faster time to post than Masimo Signal Extraction Technology™* (SET™*). A prospective single site study of 60 newborns delivered via Cesarean-section showed34:
It is important to note that pulse oximetry accuracy depends on certain human factors, such as probe placement, highlighting the need for complete and regular clinician training.11 39
Adhesive sensors on pulse oximeters may pose a risk for skin trauma, especially to the fragile skin of a newborn.38 The Nellcor™ OxySoft™ sensor’s adhesive helps enable easy removal without the skin stripping that can cause pain and secondary trauma to fragile, delicate or thin skin. Nellcor™ OxySoft™ SpO2 sensor with a new silicone adhesive, lower profile, and flexible circuit — so it:
- removes 87% less skin cells from fragile skin40
- stays in place to keep up with those little wiggles

The Nellcor™ pulse oximetry monitoring system should not be used as the sole basis for diagnosis or therapy and is intended only as an adjunct in patient assessment.
