# Device Description

The Arctic Sun™ Stat Temperature Management System is a non-invasive, thermal regulating device that monitors and controls patient temperature within a range of 32°C to 38.5°C (89.6°F to 101.3°F). The system consists of a console, non-sterile single patient use ArcticGel™ Pads, and associated accessories.

The Arctic Sun™ Stat Temperature Management System circulates temperature-controlled water ranging between 4°C and 40°C (39.2°F and 104°F) through the ArcticGel™ Pads, resulting in heat exchange between the water and the patient. A commercially available Yellow Springs Instrument (YSI) 400 series compatible patient temperature probe connected to the console provides patient temperature feedback to an internal control algorithm which automatically increases or decreases the circulating water temperature to achieve a pre-set patient target temperature determined by the clinician. The Arctic Sun™ Stat console has the option to provide secure data output of device monitoring values; there is no patient-identifiable information. The data output functions, including USB, RS-232, and Wi-Fi, do not allow the user to write to the device and are intended for user convenience only.
