Notes:

[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] 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.

[4] E.g. hand pump; LifeFlow-like devices, etc.

[5] Based on manufacturer’s published data, the device cannot warm blood or near freeze fluids in flow rates exceeding of 100ml/min. Therefore, high flows generated by push-pull resuscitation techniques may be difficult for the device to handle. It is recommended to consult with the manufacturer.

DISCLAIMERS: The table above compares selected product attributes of Quantum™ (a registered trademark of Life Warmer®) with those of the Warrior configurations (manufactured by Quality In Flow, or QinFlow). Quality in Flow is not affiliated with Life Warmer®. The benchmarking is based on publicly available information. The Quantum™ IFU / User Manual used for this study may not be the most updated version. Further, the manufacturer may change it 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. Life Warmer® 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 Quantum™ 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).
