FORE-SIGHT Tissue Oximeter During Cardiac Surgery

The purpose of this research study is to collect data from a tissue oximeter device that
measures brain oxygen saturation simultaneous with data from the same device that monitors
skeletal muscle during cardiac surgery. This monitoring will allow for continuous,
non-invasive, and earlier assessment of perfusion abnormalities/hypoperfusion.

Two sensors from the FORE-SIGHT Elite monitor will be placed on the forehead above the
eyebrows and two additional sensors will be placed on the leg muscles. Data from the
FORE-SIGHT Elite monitor will be recorded in addition to clinical and demographic data, which
is standard of care during the procedure, for research purposes to look at factors associated
with desaturations.

Inclusion Criteria:

- Subjects where cerebral oximetry is monitored during their surgery

Exclusion Criteria:

- Birthmarks, tattoos, or other skin abnormalities that FORE-SIGHT Sensors cannot avoid
