Temperature Management ZOLL's Intravascular Temperature Management provides the power and control you need to rapidly, safely, and effectively manage the core body temperature of critically ill or surgical patients. Why Temperature Management Matters Temperature is one of the four main vital signs, and temperature management has long been recognized as vital to life. Today, major medical societies recommend temperature management as the standard of care therapy for many critically ill or surgical patients. Traditional external temperature management methods, such as cooling and warming blankets, gel pads or ice packs remain common in ICU's, burn centers, emergency departments, and surgical suites. However, nurses and physicians recognize the limitations of external methods in that they are clinically inefficient, labor intensive and limit access to critically ill patients. ZOLL’s Intravascular Temperature Management (IVTM™) method has been recognized as a safe and effective method for controlling core body temperature. Superior, in fact, to other cooling methods for achieving and maintaining target temperature.1 How ZOLL Temperature Management Works ZOLL proprietary IVTM™ technology gets to the core of the temperature issue by managing patient temperature from the inside out. A ZOLL catheter is inserted into the central venous system of a critically ill or surgical patient (femoral, subclavian, or internal jugular insertion). The ZOLL Thermogard XP® thermal regulation system controls the temperature of the saline circulating through the catheter balloons via remote sensing of the patient’s temperature. The patient is cooled or warmed as venous blood passes over each balloon – exchanging heat without infusing saline into the patient. 1Comparison of different cooling methods to induce and maintain normo-and hypothermia in ICU patients: a prospective intervention study", Hoedemaekers, et al.
