WARNINGS
All IV fluid bags must be vented of air per IV fluid manufacturers’ directions prior to
connecting to the infusion set. Standard IV line protocols for priming the complete
infusion set, the enFlow Disposable Cartridge, and the extension set must be followed
before connecting to a patient. Care must be taken to ensure there is not sufficient air in
the fluid bag and lines to cause an air embolism.
The 'High Priority Alarm' is a flashing RED LED, a flashing RED Controller display, and an
audible alarm, indicating that the infusate is over temperature. Stop the fluid flow, and
slide the Warmer covers open to stop warming. If the above occurs, then replace the
Warmer and contact Technical Support. The attending practitioner should remain within
4m of the patient when the device is in use to enable visualisation of the enFlow display
and hear the audible high priority alarm.
The Warmer contains magnets; do not operate within 15 cm (6 in.) of a pacemaker or
other devices that may be sensitive to strong magnetic fields.
The Disposable Cartridge may be a potential biohazard during or after use. Handle and
dispose of in accordance with acceptable medical practice and applicable regulations.
Do not use in the presence of flammable anesthetics.
Replace the fuses with only Bussmann
®
part # GDB 5A or equivalent. Bussmann
®
is
registered in the United States or abroad by Cooper Industries, Inc. or its subsidiaries.
The Disposable Cartridge should not be used for greater than 24 hours.
Ensure that the Disposable Cartridge expiration date has not passed.
If the IV line runs dry, disconnect the Disposable Cartridge from the Warmer. Re-prime
the entire IV system using aseptic techniques. Ensure all the air is removed from both the
line and the Disposable Cartridge. Replace the Disposable Cartridge in the Warmer.
The enFlow Warmer is to be
used only with approved enFlow power sources and the
enFlow Disposable Cartridge.
To avoid risk of electric shock, this equipment must only be connected to a supply main
that is grounded. Should the need arise the device may be disconnected by the appliance
coupler.
Cautions
Follow the AABB "Guidelines for the Use of Blood Warming Devices" (© 2006) which caution
against warming when administering platelets, cryoprecipitate, or granulocyte suspensions.
Some drugs or drug preparations may be sensitive to warming. As with any fluid or blood
warming system, carefully review the drug manufacturer's literature for information about
thermal sensitivity.
The disposable cartridge contains aluminum. Review the preparation or solution
manufacturer's instructions for use about chemical sensitivity.
Do not affix, place or bind the Warmer directly to a patient during general use.
Do not wrap the Warmer in towels, sheets, blankets or drapes.
If the enFlow system is used for pre hospital transport or transfer to another facility
o
place an insulating and cushioning fabric layer, such as soft cotton towels or gauze, at
least .25” or 6 mm thick in between the underside of the Warmer and the patient. Do not
use foam or gel pads. Cushioning the patient from the Warmer will help prevent
perioperative peripheral neuropathies.
The Warmer heating surface and Disposable Cartridge can get quite warm when heating
cold IV fluids/blood at high flow rates. Wait a few seconds after stopping the IV fluid/blood
flow before removing the Disposable Cartridge.
The Controller should only be plugged into a hospital grade outlet.
