Pulse Oximetry clinical trials at University of California Health
3 research studies open to eligible people
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.

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.
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.
