[1] The term “Max Delivery Rate” means “the maximum flow rate in which target temperature – typically 38°C — will be reached”.
[2] E.g. hand pump, LifeFlow-like devices, etc.
[3] 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.
[4] To facilitate warming during interfacility and intra-facility transports.
