Arctic Sun^® Technology

The Arctic Sun Temperature Management System is a water-based, non-invasive thermoregulatory device that monitors and automatically controls patient temperature within a range of 33°C to 37°C (91.4°F to 98.6°F). The Arctic Sun System consists of the Control Module and single-use ArcticGel Pads. Each of these components offers important benefits to provide the unique advantage of safe, rapid deployment of therapy and efficient temperature modulation.

The ArcticGel Pads, the key component of the Arctic Sun System, have a unique construction that includes a water based, biocompatible hydrogel layer. The hydrogel coated pads cover minimal body surface area and adhere to the patient’s abdomen, back and thighs. The Arctic Sun pulls water under negative pressure through the pads at a high velocity in a temperature range between 4°C and 42°C (39.2°F and 107.6°F) for rapid heat exchange. The negative pressure flow prevents water leakage and helps ensure a safe and hassle-free work environment.

The other key component, the Arctic Sun Control Module, incorporates an internal control algorithm that reacts to patient temperature by automatically adjusting the circulating pad water temperature to achieve a preset patient target temperature. The temperature feedback from the patient is supplied to the control module using standard YSI-400 patient temperature probes, such as bladder, rectal, esophageal or nasopharyngeal probes.

The combination of an efficient control algorithm and thermal conductivity of the hydrogel results in thermoregulatory system that surpasses many expectations and proves to be a useful tool for patients undergoing therapeutic temperature modulation.

The control algorithm uses a feedback loop to automatically increase or decrease the circulating pad water temperature in order to achieve a pre-set patient target temperature.
