[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] “At an input temperature of 20°C and a flow rate of 50 mL/min, the enFlow warmed over 2.4 L to above 36°C before depleting the battery, over 2.8 L at 100 mL/min with minimal decrease in output temperature and over 3.3 L at 200 mL/min with average output temperature of 34.2°C. At an input temperature of 10°C and a flow of 50 mL/min, the enFlow warmed over 1.6 L to above 36°C, with an increase in total heated volume and a substantial decrease in output temperature as the flow rate increased to 100 and 200 mL/min (1.8 and 2.3 L, at 33.7°C and 25.7°C, respectively)”. (Lehavi A, Yitzhak A, Jarassy R, et al. Emergency Med Journal, doi:10.1136/ emermed-2017-207112). Note: the study tested the battery version of the product, not the AC version

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

[5] Based on manufacturer’s published data, and as reflected in the independent study results mentioned above, warming efficiency may not suffice for very intense bolus flows. It is recommended to consult with the manufacturer.

[6] Optional IV extension set: 0.5 ml.

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

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

[9] Product on global recall due to aluminum toxicity concerns.

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

Quality in Flow is not affiliated with Vyaire™ Medical. The benchmarking is based on publicly available information and the respective device’s Instructions for Use (IFU) / User Manual, where applicable. The enFlow® 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. Vyaire™ 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 buddy enFlow™ 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).
