  • Neonatal Pulse Oximetry Disparities Due to Skin Pigmentation

    open to all eligible people

    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.

  • Mobile Biosensor for Measuring Vital Signs in Healthcare and Home Settings

    open to eligible people ages 13 years and up

    This study will record vital signs (heart rate and blood oxygen levels) using a new cell phone integrated biosensor and compare it to routine measurements carried out in the clinics and hospital at UCSD. Cell phones will be given to a selected group of subjects for use at home and data collected.

  • Oxygen Saturations Across Tones of Skin

    open to eligible people ages 18-99

    Pulse oximetry, or SpO2, is a vital sign used across healthcare systems to gauge how much oxygen blood is carrying as a percentage of the maximum it could carry. Recent research has suggested that current SpO2 monitors may inaccurately report high SpO2 in patients with darker skin tones when the actual oxygenation is at unsafe, low levels. Additionally, this new research suggests as the SpO2 levels decrease, the risk of occult hypoxia rises. The investigators hypothesize melanin interferes with the pulse oximetry accuracy. Investigators will use spectrophotometry to measure melanin indices and other variables to test this hypothesis.

  • Pulse Oximetry Errors in Hospitalized Patients Across Varying Skin Pigmentation

    open to eligible people ages 18 years and up

    This is a prospective observational study designed to quantify and understand errors in pulse oximetry in hospitalized patients in relation to their skin pigmentation. It is driven by three recent retrospective studies showing missed diagnosis of hypoxemia in patients across a spectrum of skin pigmentation, defined as blood SaO2 <90% when their pulse oximeter reads 92% or greater.
