The Compact Disposable Unit (CDU) cannot control nor impact the flow; it should be viewed as merely a smart line extension, especially since it has the same internal diameter of your standard fluid/blood tubing. Your actual flow rates will be dictated by multiple factors such as fluid type (WB, RBC, plasma, clear fluids), the infusion method (e.g. gravity, pressure bag, electrical pump, hand pump, syringe, push-pull, LifeFlow, etc.), the access type (IO, IV, Central, etc.), the catheter size, and the line setup (the use of additional filters, extensions, J-loops, etc.).
Based on the above, instead of using the term “flow rate” (which we do not control) we prefer to use the term “delivery rate” (which we fully control) to describe the warming ability of each of our various configurations.
With respect to the Warrior lite, at 4°C fluids/blood input temperature, the delivery rate of the Warrior lite is up to 170mL/min with lite battery and up to 180 mL/min with Extra Power battery. Similarly, at 20°C fluids/blood input temperature, the delivery rate of the Warrior lite is up to 250mL/min with lite battery and up to 270 mL/min with Extra Power batter. These delivery rates apply to fully charged batteries. If the flow rates exceed the capacity of the system, the system will continue warming to the best of its capabilities yet set temperature may not be reached. In such a case, appropriate indication will be provided to the user.
