|Full Title||Changes in 13CO2/12CO2 Delta Value in Exhaled Breath as an Early Indicator of Infection in Adult Trauma Subjects|
|Principal Investigator(s)||Ann P O'Rourke, MD, MPH, FACS|
Carbon-12 and carbon-13 are naturally-abundant isotopes in exhaled breath carbon dioxide. The ratio of carbon-13 to carbon-12 in exhaled breath is known as the breath delta value. This study is seeking to determine if the breath delta value of adults with trauma is an early indicator of the onset of infection that may lead to sepsis.
