NCT06063148
Neonatal Pulse Oximetry Disparities Due to Skin Pigmentation
The goal of this clinical trial is to determine if pulse oximeters show an SaO2-SpO2 discrepancy that correlates with skin pigmentation such that pulse oximetry will overestimate oxygenation in newborns with darker skin. The main questions it aims to answer is if SaO2-SpO2 discrepancy varies with the degree of skin pigmentation among neonates, if gestational age has an influence on SaO2-SpO2 discrepancy, and if packed red blood cell (PRBC) transfusion has an influence on SaO2-SpO2 discrepancy in newborns with various degrees of light and dark skin. Researchers will compare SaO2 and SpO2 values in neonates of various skin pigmentation.

Skin Pigment/Pulse Oximeter in Congenital Heart Disease (CHD)
Recent retrospective studies have demonstrated differences between pulse oximeter values (SpO2) and measured arterial oxygen saturation (SaO2) in patients identifying as Black or Hispanic. These retrospective studies have limitations because self-reported race is likely not an accurate metric for level of skin pigmentation and the retrospective nature of these studies may impact the accuracy of simultaneous measures of arterial oxygen saturation and pulse oximeter values. The few prospective studies that have evaluated this issue have utilized color-matching techniques to quantify skin pigmentation, and fewer studies have directly measured skin pigmentation in relation it to pulse oximeter accuracy. The aim of this study is to prospectively measure pulse oximeter accuracy in relation to measured levels of skin pigmentation in the congenital heart disease population.

Macular Pigment Measurements in Eye & Other Tissues
The purpose of this study is to understand the role of nutrition and its effects on the eye and other tissues. The investigators propose to study this by validating and correlating various non-invasive measurement methods of carotenoid concentrations in the human eye and skin tissue. A secondary objective is to correlate blood levels of carotenoids on a sub-set of participants.
