Protection of Human Subjects Since non-invasive temperature monitoring poses no risk to patients and is part of usual care and since the investigators will not collect or record any protected health information (PHI), written informed consent will not be sought. Patients will be identified by their study ID number only. The data will be collected by a registered nurse data collector familiar with the intensive care setting and data will be stored in a locked file cabinet in the researchers locked office. Temperature data for the Temp-Traq is collected through the Temp-Traq Application (AP) which will be placed on a Cleveland Clinic Approved and encrypted i-pad. Once the study is completed and all data has been transferred to the study database, the Temp-Traq application and all of its data will be deleted from the i-pad.
