Overview of the Blanketrol II Hyper/Hypothermia System
Please Note: Refer to the Manufacturer’s Operation Manual for full product description, operating, and maintenance instructions.
The Blanketrol II system is used either: to lower or to raise a patient’s temperature and/or maintain a desired patient temperature through conductive heat transfer. The Blanketrol II unit itself is composed of a heater, a compressor, a circulating pump, and a microprocessor board. Other components of this thermoregulation system include disposable blankets designed to circulate warm or cool distilled/sterile water, connecting hoses with quick-disconnect male and female couplings, and a YSI 400 series single-patient use esophageal probe. The system heats or cools water and pumps the water from the unit to a blanket. The blanket rests under the infant and is designed so that the water circulates through the blanket and returns back to the unit.
The system functions in three modes: Manual Control Mode, Automatic Control Mode, and in a Monitor Only Mode. Whole body cooling will utilize the Manual and Automatic Control Modes only. The Manual Control Mode will be used first to set the desired temperature of the circulating water to 5°C (Setpoint) in order to pre-cool the blanket prior to placing under the infant. A YSI 400 Series esophageal probe will next be inserted into the infant and connected to the Blanketrol II Unit, which will allow for the servo mechanism in the Automatic Control Mode. In this mode the operator will set the desired temperature of the infant to 33.5°C (Setpoint). The esophageal probe is used to measure the actual temperature of the infant and this measurement is compared with the desired Setpoint temperature by the
unit’s microprocessor. Throughout cooling and re-warming, if the infant’s actual temperature is lower/higher than the desired Setpoint temperature, the Blanketrol II Unit will heat/cool the circulating water so that the infant’s temperature is raised/lowered to reach the desired Setpoint. While the infant lies on a 25” x 33” blanket, the extent of blanket water temperature fluctuation, around the setpoint, is lessened by simultaneously operating a larger, 25” x 64” blanket suspended near the unit.
