Pulse Oximetry clinical trials at UCSD
2 research studies open to eligible people
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.
