SAFETY PRECAUTIONS
READ THE FOLLOWING INSTRUCTIONS CAREFULLY BEFORE •
OPERATING THE COLD RUSH COLD THERAPY SYSTEM.
Correct temperature range for each patient’s skin should be •
determined on an individual basis by a licensed healthcare
practitioner. Patients vary in sensitivity to cold. Periodically
monitor the temperature and appearance of the skin being treated
once steady flow of water through the pad is achieved.
The temperature at the surface of the skin may vary depending •
upon the amount of dressing used and other factors beyond the
control of the manufacturer. Temperature and color of the skin, at
the treatment site, must be monitored by a licensed healthcare
practitioner.
Fill with water and ice only, do not overfill.•
The Cold Rush Pad should never be applied directly to the patient’s •
skin. Do not use the Cold Rush Cold Therapy System without first
applying an insulation barrier between the Cold Rush Pad and the
patient’s skin.
Unit is not suitable for use in the presence of flammable anesthetic •
mixture with air, oxygen or nitrous oxide.
Follow local ordinances or regulations for proper disposal of •
device, accessories and packaging.
Caution:• Federal law requires this device to be sold by a physician
or by the order of a physician.
