The 3M™ Bair Hugger™ control unit
The control unit displays noninvasive core temperature measurements obtained from the temperature sensor.
The current temperature is displayed numerically, and previous temperature data is displayed graphically as a
temperature trend graph. When the sensor is plugged into the sensor cable and equilibration is achieved, the
control unit reads up to the last two hours of stored temperature data and displays the temperature trend graph.
Disconnections of the sensor from the sensor cable are indicated by gaps in the temperature trend graph.
The current temperature measurement can be continuously transmitted to a patient vital signs monitor through the
optional monitor cable. To transmit data from the temperature monitoring system to the patient's monitor, simply
connect the appropriate monitor cable between the back of the control units 3.5mm diameter X 14mm monitor
jack and the YSI-400 type input on the patient monitor.

Back of control unit
To view information and connections
on the back of the control unit, assure
that controller is viewed from a
distance no further than 15" (38 cm)
from the operator.
The monitor cable port provides
a resistance that corresponds to a
YSI-400 thermistor at the displayed
temperature. It is electrically isolated
from the control unit.
