Glucose Time-In-Range Development Evaluation

The study will evaluate patients requiring frequent glucose monitoring in a Surgical ICU. The study population includes surgical critical care patients who require blood glucose monitoring. Subjects must have a vascular access device \[i.e., Central Venous Catheters (CVC), Multi-lumen Access Catheters (MAC) either in place or to be placed with an expected usage of at least 48 hours. During Phase One of the trial, patients will be connected to the OptiScanner for up to 72 hours and the hospital's current standard of care for glucose management will be followed.
