Insights
Early pulse oximetry screening (POS) can identify critical congenital heart disease (CCHD) in newborns before hospital discharge. This simple test aids early diagnosis, reducing infant death and improving outcomes worldwide.
Area of Science:
- Neonatal screening
- Pediatric cardiology
- Public health interventions
Background:
- Critical congenital heart disease (CCHD) is a leading cause of infant mortality and morbidity globally.
- A significant percentage of infants with CCHD are undiagnosed at birth, leading to delayed interventions.
- The diagnostic gap for CCHD is presumed to be wider in low-resource settings.
Purpose of the Study:
- To evaluate pulse oximetry screening (POS) as a method for early CCHD detection.
- To demonstrate that POS meets criteria for universal newborn screening.
- To advocate for the worldwide adoption of POS for CCHD screening.
Main Methods:
- Review of data from large randomized trials on universal POS implementation.
- Analysis of POS effectiveness in identifying CCHD in newborns before discharge.
- Assessment of POS against established universal newborn screening criteria.
Main Results:
- Universal POS at discharge significantly aids in the early diagnosis of CCHD.
- Evidence supports POS as a reliable tool for detecting CCHD in neonates.
- Data indicates POS is suitable for integration into universal newborn screening programs.
Conclusions:
- Universal pulse oximetry screening is an effective strategy for early CCHD detection.
- POS meets the necessary criteria for inclusion in universal newborn screening.
- Worldwide adoption of POS screening for CCHD is recommended to improve infant outcomes.
Abstract:
Critical congenital heart disease (CCHD) is a major cause of infant death and morbidity worldwide. An early diagnosis and timely intervention can significantly reduce the likelihood of an adverse outcome. However, studies from the United States and other developed countries have shown that as many as 30%-50% of infants with CCHD are discharged after birth without being identified. This diagnostic gap is likely to be even higher in low-resource countries. Several large randomized trials have shown that the use of universal pulse-oximetry screening (POS) at the time of discharge from birth hospital can help in early diagnosis of these infants. The objective of this review is to share data to show that the use of POS for early detection of CCHD meets the criteria necessary for inclusion to the universal newborn screening panel and could be adopted worldwide.

Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.

01:17Assessment of apical pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:
01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
