Summary

This is a prospective longitudinal study to study the agreement between a continuous glucose monitoring system (CGMS) versus current blood glucose monitoring. Subjects in this study will have their blood glucose measured regularly every 1-3 hours with current methods in the Cardiovascular Intensive Care Unit (CVICU), and by Point of Care (POC) fingerstick glucose using the Accucheck Inform II on the regular floors, and the CGMS reading at the same time will be captured. Subjects will have measurements taken throughout their stay in the CVICU and on the regular floors. Agreement and correlation between systems, as well as errors, will be calculated.

Detailed description

The Dexcom G7 will be placed either by an anesthesiologist or nurse anesthetist, or critical care physician, nurse or nurse manager upon arrival to CVICU, post cardiac surgery. Standard of care: Accuchek will be done per standard of care for post operative patients that are in ICU
