The Warrior’s Compact Disposable Unit (CDU) senses the flow and reacts to it yet it does not control the rate of the flow whatsoever. It should be perceived as merely smart line extension, with the same diameter of your standard fluid/blood tubing. Flow rates should be induced by gravity, pressure bag, electrical pump, hand pump, syringe, or any other flow-inducing mechanisms. Catheter size naturally impacts the flow as well. Therefore, instead of using the term “flow rate” we use the term “delivery rate” to describe the warming ability of each configuration. At 4°C fluids/blood input temperature, the delivery rate of the Warrior lite with Extra Power battery is 180mL/min. Similarly, at 20°C fluids/blood input temperature, the delivery rate of the Warrior lite with Extra Power battery is 270mL/min. These delivery rates apply to a fully charged battery and measurement at room temperature ambient. We are aware of users reaching a flow rate of 250mL/min while using flow-inducing mechanisms in the field.
