The limitations of pulse oximetry might not have much impact in the sleep laboratory, where several other parameters are monitored to aid in the interpretation of the study. However, these limitations become of major importance in the application of pulse oximetry alone as a screening Cited by: 344. Pulse Oximetry – Congenital Heart Defects Screening for Newborns As the number one killer of infants with birth defects, congenital heart defects take a significant toll on families across the country. Fortunately there is non-invasive screening test that helps identify newborns at risk for heart defects and potentially save their lives.
Screening with pulse oximetry can identify a number of types of CCHD, the most common of which are shown in the box below. While not the main targets of screening, many conditions other than CCHD may present with hypoxmia and thus likewise be detected via pulse oximetry. Note: As with any screening test, sometimes there can be times when the pulse oximetry screening test is not correct. Sometimes there can be false positives, meaning that while the pulse ox screen suggests a problem, the echo will be reassuring that the heart is normal.
Adult Screening. Pulmonary AVMs (Lung AVMs) Lung AVM screening is recommended every 3-5 years, if a pulse oximetry test result is 97% or higher. If a pulse oximetry result is lower than 97%, or a child is short of breath, additional tests or treatment may be required. Jul 11, 2016 · Pulse oximetry has been the mainstay procedure for indirectly detecting hypoxemia in medically ill patients since the 1980s.16,17 The screening of CCHD by pulse oximetry involves taking advantage of its ability to detect clinical and more importantly subclinical levels of hypoxemia that should raise suspicion for a CCHD. However, pulse oximetry Cited by: 4.
