Barkey warming devices heat blood and blood products as well as infusion solutions directly to the patient.


    The Barkey autocontrol represents the control unit to which the Barkey autoline is connected. The Barkey autocontrol controls the temperature of the Barkey autoline and heats blood and infusion solutions with the green Barkey autoline warming profile – similar to the Barkey S-line.
    The Barkey warming system, consisting of autocontrol and autoline as well as optional autotherm, offers the possibility to choose between a temperature range of +33°C to +43°C compared to the Barkey S-line. This allows higher flow rates to be achieved than, for example, with the Barkey S-line.

    Blood and infusion warmers, such as the Barkey autocontrol with autoline, are an important component in the prevention of hypothermia. A body core temperature below +36°C is called hypothermia[1]. Causes for such a decrease are cold ambient temperatures, operating tables and, among other things, cold infusions and transfusions[2]. In the journal Anesthesiology, Sessler describes how quickly the core body temperature drops. Cold blood products and infusions lower the body core temperature by 0.25°C per unit. This effect is additionally intensified as soon as the patient is sedated. Due to an inhibition of the hypothalamus (responsible for thermoregulation) no centralization of the blood in the core of the body takes place, but this is transported to the periphery of arms and legs. This leads to a drop of 1.6°C already in the first hour during an operation[3]. Therefore, the American Society of Peri Anesthesia Nurses recommends infusing warm infusion solutions[4].

    This risk can be minimised with the Barkey autocontrol in combination with autoline. The effects of hypothermia include prolonged hospital stays, patient discomfort (e.g. shivering), reduced wound healing and higher follow-up treatment costs[5],[6].

    In analogy to the Barkey S-line, the Barkey autocontrol is first attached to an infusion stand or standard rail and switched on. As soon as this step is completed, the Barkey autoline is connected to the control unit. The display shows the automatic connection of the heat profile as well as the set value. Insert a standard infusion set into the green warming profile and the Barkey warming system is ready for use. The use of disposable articles is completely dispensed with.
