Title: Muscle Tissue Oxygen Saturation as a Marker of Oxygen Delivery in Hospitalized Cats
Annual Direct Cost: $4,000
Project Period: 06/1/2011-08/31/2011

DESCRIPTION (provided by applicant):  In critically ill cats, the underlying disease process often leads to decreased supply of nutrients such as oxygen to vital organs. If these deficits are not detected early, organ function can be compromised, leading to more rapid progression of the disease or death. The current gold standard technique for determining if enough oxygen is being delivered to the organs requires placement of a catheter into a large vein in the center of the body, an invasive and sometimes dangerous procedure. A new technology that measures the amount of oxygen in muscle tissue non-invasively by shining an infrared light through the skin has been shown to be a reliable marker of deficits in oxygen delivery to the organs. This device, the InSpectra StO2 Tissue Oxygenation Monitor, is currently being used to monitor critically ill people, and it is the goal of this study to evaluate the capability of this technology in critically ill cats. The monitor will be placed on hospitalized cats in the ICU at Cornell University's Companion Animal Hospital in which the previously mentioned central catheters have already been placed for other reasons, and readings from the monitor will be taken when blood samples are being collected as part of the routine monitoring ordered by the clinician. The measurements from the monitor will then be compared with the results of the blood work to determine if, like in people, the non-invasive readings match the data from the invasive central catheters. If this new technology works in critically ill cats, it will have a significant impact on our ability to treat these difficult to monitor patients, and will likely result in better outcomes in these critically ill patients as it has in critically ill people.
