Thenar Tissue Oxygen Concentration (StO2): A Non-invasive Surrogate for Central Venous Oxygen Saturation (ScvO2)

Summary

Oxygen concentration for patients undergoing cardiac catheterization and during admission to an intensive care unit is important outcome measure for clinical care. Currently, the tool used to monitor the oxygen concentration is a central venous access positioned in the superior vena cava or in the pulmonary artery to monitor the central venous oxygen saturation (ScvO2). However, it is invasive and not always possible due to a lack of a central line access. In this research study, the investigator would like use a noninvasive means for the ScvO2 by using the thenar tissue oxygen concentration (StO2). The primary aim for the study is to determine if the thenar StO2 correlates with ScvO2 and can serve as a noninvasive surrogate for ScvO2.

Conditions

  • Oxygen Concentration Levels

Interventions

DEVICE

StO2 measurement

All participants will have a measurement of the tissue oxygen concentration (StO2) level after applying the noninvasive probe to the thenar eminence. This measurement is done at the same time as a blood gas from the central venous catheter is obtained. The StO2 measurement is documented once for the subject in the study.

Blood Gases
