[1] The term “Max Delivery Rate” means “the maximum flow rate in which target temperature – typically 38°C — will be reached”. Obviously, this measure relates to battery capacity as well; the assumption therefore is that a fully charged battery is used.

[2] “At an input temperature of 20°C and a flow rate of 50 mL/min, the Warrior warmed over 3.5 L to an average temperature of 37.8°C. Flow rates of 100 and 200 mL/min increased total heated volume with small effect on the output temperature (4.3 and 4.8 L at 37.1°C and 36.1°C, respectively). This behaviour persists at an input temperature of 10°C—warming 2.6, 2.9 and 3.3 L to 36.9°C , 35.9°C and 34.4°C at flow rates of 50, 100 and 200 mL/min, respectively. (Lehavi A, Yitzhak A, Jarassy R, et al. Emergency Med Journal, doi:10.1136/ emermed-2017-207112).

[3] “At an input temperature of 20°C and flow rates of 50 mL/min and 100 mL/min, the Thermal Angel warmed just under one litre to approximately 36°C. As flow rate increased to 200 mL/min, nearly 1.5 litres reached a substantially lower temperature of 31°C. At an input temperature of 10°C and a flow rate of 50 mL/min, the Thermal Angel warmed under 700 mL to 34°C, with an increase in total heated volume and a further, substantial decrease in output temperature as the flow increased to 100 and 200 mL/min (800 mL and 1.5 litres, at 29.4°C and 20.9°C, respectively).” (Lehavi A, Yitzhak A, Jarassy R, et al. Emergency Med Journal, doi:10.1136/ emermed-2017-207112)

[4] The term “Battery Capacity” means “the volume of fluids – in liters — that can be warmed with a single, fully charged battery”. Actual output is subject to battery condition, ambient temperature (typically 20°C ambient is assumed) and flow rates.

[6] Based on the independent study results mentioned above, warming efficiency may not suffice for very intense bolus flows. It is recommended to consult with the manufacturer.

DISCLAIMERS: The table above compares selected product attributes of Thermal Angel® (manufactured by Estill Medical Technologies Inc.) with those of the Warrior configurations (manufactured by Quality In Flow, or QinFlow). Quality in Flow is not affiliated with Estill Medical Technologies Inc. The benchmarking is based on publicly available information. The IFU / User Manual of the Thermal Angel® may change as the product evolves; QinFlow may not know about such updates and in any event does not undertake to update the information in the table upon such changes. Unless stated differently, the benchmark information was commissioned by QinFlow alone and not all data points were independently verified. Estill Medical Technologies Inc. was not part of this benchmark study. Use of the Warrior is subject to QinFlow’s terms of use. This benchmark study does not intend to cover all the differences between the devices. QinFlow does not guarantee that Thermal Angel® will achieve the results or perform as mentioned in the benchmark study. QinFlow only warrants the information published in its IFUs (performance data points above are in accordance with the CE marks of each Warrior configuration; for FDA-cleared IFU, where applicable, contact QinFlow).
