[1] The term “Max Delivery Rate” means “the maximum flow rate in which target temperature – typically 38°C — will be reached”.

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

[4] Based on manufacturer published data, the device cannot warm blood or near freeze fluids in flow rates exceeding 83ml/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.

[5] The longer the distance, the more likely that fluids will get colder as they travel towards the patient, especially at low flows.

[6] To facilitate warming during interfacility and intrafacility transports.

[7] Rounded price at high volume. Coming soon – lower-cost option ($15-30)

DISCLAIMERS: The table above compares selected product attributes of Hotline® (a registered trademark of Smiths Medical, which is part of the global technology business Smiths Group plc) with those of the Warrior and Warrior AC configurations (manufactured by Quality In Flow, or QinFlow). Quality in Flow is not affiliated with Smith Medical. The benchmarking is based on publicly available information and the respective device’s Instructions for Use (IFU) / User Manual, where applicable. The Hotline® IFU / User Manual used for this study may not be the most updated version. Further, the IFUs / User Manuals used for this study may be changed by the manufacturer as the products 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. Smith Medical 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 Hotline® 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).
