Intravascular Temperature Technology
ZOLL’s Intravascular Temperature Management (IVTM™) technology is used to regulate the core body temperature by precisely cooling and warming critically ill and surgical patients suffering from a variety of medical conditions. According to the company, the technology provides cooling and warming from a catheter inserted into the patient’s vein. This provides better control of the core body temperature by directly cooling or warming the patient’s blood as it flows through the body. This catheter is connected to the Thermogard XP console, which when used to induce hypothermia, circulates ice-cold saline solution inside the balloon catheter. After a period of therapeutic hypothermia, typically 12-24 hours, the system slowly and accurately rewarms the patient back to normal body temperature. Since the saline flows only within the catheter, no fluid is infused into the patient. A variety of catheter options are available depending upon the specific patient needs.
