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.

Due to highly stable components, microprocessor control, and built-in self-tests, an annual performance check is sufficient. • The steps listed in the enFlow IV fluid/blood warming system operational checklist (Appendix F) should be performed at least once a year, or as required by your accrediting body.
IV fluid/blood warming system description The enFlow IV fluid/blood warming system consists of the enFlow Warmer (Model 100 series), the enFlow Controller (Model 121 series), the enFlow Disposable Cartridge with IV extension set (Model 202) or without IV extension set (Model 200). Within seconds, this warming system delivers normothermic infusate to the patient at flow rates of Keep Vein Open (KVO defined as 2 mL/min) to 200 mL/min when input fluid temperature is 20 °C.
Unpacking the enFlow IV fluid/blood warming system Upon receipt of the enFlow IV fluid/blood warming system components, visually inspect the shipping containers and internal contents for damage that may have occurred during shipment. If there is any visible or mechanical damage to the contents, or if the order is incomplete, please contact Customer Service immediately.

3. Wipe the surface of the Controller, taking care not to leave excess residual cleaner on the Controller. If fluid ingress is detected, set the Controller aside for an extended period of time to allow it to dry. Storing the enFlow IV fluid/blood warming system components The Warmer and Controller should be stored in a clean, dust free environment. (See Appendix A)
Servicing the enFlow IV fluid/blood warming system components The enFlow IV fluid/blood warming system components have been designed to be durable and long lasting. The system uses current Surface Mount Technology (SMT) and materials. If a System Fault error occurs, then remove the device from service and refer to the table in Appendix B for proper evaluation and handling.

Temperature control The enFlow IV fluid/blood warming system includes multiple safety features to prevent overheating of infusion fluids. There are built-in redundancies and back-up safety systems as means for protection in the event of a failure in the primary control mechanism. Several aspects of the system work together to accomplish desired and appropriate safety: 1.
Confirm the enFlow and the ECG monitor are plugged into different outlets There are two reasons for this action. It is possible that the two systems are in an electrical phase related conflict, which is being expressed on the monitor. Secondly, it is possible that the outlets are not properly grounded or grounded in different locations.
Relative Humidity Range: 10% to 90% Cleaning the enCheck 1. Use only approved cleaning solutions. (Please reference “Cleaning the enFlow IV fluid/blood warming system components” for a list of approved cleaning solutions.) 2. Moisten a clean cloth with the cleaning solution; do not spray or pour cleaning solutions directly onto the enCheck.
Note: Electromagnetic Compatibility (EMC) The enFlow IV fluid/blood warming system has been tested and found to comply with the limits for medical devices as set forth in IEC 60601-1-2: (2014) and related standards. These limits are designed to provide reasonable protection against electromagnetic interference (EMI) in a typical medical installation.

Page 30
Purpose The purpose of this test is to check the leakage of current from the Warmer into saline. As IV fluids are generally conductive, a fluid warmer is considered to be electrically connected to the patient similar to an ECG lead; therefore, the leakage needs to be tested. The setup for this procedure is described below. Safety Analyzer Wire Procedure...

Purpose The enCheck Tester was developed to quickly and reliably trigger the over-temperature alarm condition on the enFlow Warmer. Within seconds, the enCheck unit will heat the Warmer to an over- temperature scenario causing the alarm to sound. Additionally, the enCheck is designed to verify the Warmer operation at enFlow’s installation site.
