WARMING MATTRESS PRECAUTIONS
Use under the direct supervision of a clinician.
Monitor the patient’s vital signs regularly during warming according to institutional protocol. If vital sign
instability occurs, notify the clinician.
Exercise caution when using multiple warming methods.
Ensure that Warming Mattresses are securely fastened to the table with “THIS SIDE UP” labeling
facing up.
The risk of skin irritation caused by pooling of surgical prep solutions under the patient may increase with
warming; ensure that surgical prep solution instructions for use are followed.
Gel pad placement between Warming Mattresses and the patient is not recommended; gel pads may cause
a loss of warming performance.
Always use a thin barrier between the patient and Warming Mattresses.
Position the patient on flat Warming Mattress.
Do not use Warming Mattresses when the risk of pressure injury cannot be mitigated. Take extra
precaution to alleviate pressure under bony prominences when warming under the patient.
Maintain contact between the patient and the labeled sensor on Warming Mattress.
Do not use operating table clamps or similar devices on Warming Mattresses as they may cause damage
to the device and result in loss of the heating function and/or localized heat build-up in the damaged area.
Do not place Warming Mattresses over a table joint that will move during surgery.
Do not use Warming Mattress Overlays as a stand-alone patient pressure relief system.
Do not place any hard objects (e.g., mattress cables, EKG cables, hard cautery return pads, patient fluid
lines, etc.) between Warming Mattress and the patient.
Do not fold Warming Mattresses during use, as localized heat may build-up.
Adjust placement of Warming Mattress during X-rays as the internal wiring, located primarily along the
edges of the device, and the sensor with associated wire may appear in images.
Do not place fluid lines under Warming Mattresses or between Warming Mattresses and other warming
devices.
Do not position the patient’s head directly on Warming Mattress.
Do not partially cover the Warming Mattress with thick insulation unless sensor is also covered, or
product damage may occur.
This device should not be disposed of with general waste at end of life. Follow local regulations for
disposal. The device does not pose any potential hazard.
Any serious incident that has occurred in relation to this device should be reported to the manufacturer
and the competent authority of the country in which it occurred.
