Policy Number: 2.3.20
Category: UW Health
Type: Inpatient
Effective Date: March 24, 2017

I. PURPOSE

To regulate body temperature, i.e. to warm or cool by conductive heat or cold transfer.

II. POLICY ELEMENTS

A hypo/hyperthermia blanket will be placed on inpatient operating room tables per circulating RN, surgeon,

III. PROCEDURE

A. The Hypo/Hyperthermia unit is used and maintained according to manufacturer specifications and operating
instructions. Operator will verify proper fluid level, blanket position, and hose connections prior to use.
i. Water level should be visibly touching the strainer when unit is off.
B. The Hypo/Hyperthermia unit is used under direction of a physician. The patient will be observed for
temperature and skin condition to prevent injury to the patient.
C. The operator of the unit will verify the heating/cooling blanket operating properly by checking for leaks and
feeling the blanket for desired effect.
D. The operator will monitor the unit for audible/visual alarms. Unit will stop therapy when in alarm. If operator
presses SILENCE ALARM, audible alarm will cease for one to five minutes depending upon the criticality of
the alarm.
i. Audible/Visual Alarms occur for Low Water, Low Flow (rate <6GPH), Low Temperature (<3o C(37 o
F), Low Limit (<1 o C (34 o F), High Temperature (>44.6 o C (112 o F), High Limit (>46 o C (115 o F).
E. The operator of the Hypo/Hyperthermia unit will check the temperature SETPOINT prior to use to determine
specified temperature settings are correct. When settings are confirmed user will press MANUAL CONTROL
to begin heating/cooling.
i. When unit is set to MANUAL CONTROL the unit reports temperature of circulating water.
ii. To set the temperature press the UP arrow or DOWN arrow to change the SETPOINT display to
