Abstract: A catheter includes a catheter body, a first lumen extending through the catheter body, one or more second lumens extending through the catheter body, and two or more capillaries extending from the catheter body and coupled to the second lumens. The first lumen performs at least one of receiving a sample of the blood from a vasculature of the patient or measuring a parameter of the blood. The second lumens receive a gas enriched liquid from a gas enriched liquid source. The capillaries receive the gas enriched liquid from the one or more second lumens and to simultaneously dispense respective streams of the gas enriched liquid directly into the vasculature, such that the streams of the gas enriched liquid intersect and mix with the blood in a region beyond an end of the catheter body and beyond the first lumen.

Abstract: In some implementations, data obtained by a temperature management system for delivering temperature management therapy to a patient is presented, within a single display region, as a graph of patient temperature over time representing the timespans of all phases of a multi-phase temperature management therapy. The graph may be fitted to present each phase separately in a manner that retains data complexity. The graph may include power data representing power output over time by a temperature management device. Data from other devices may be incorporated into the graph. A portion of the data may be patient temperature data and/or patient physiological data gathered during a time preceding temperature management therapy by the temperature management device.

Abstract: A system and method for adding or removing heat from a heat exchange fluid circulating between an external heat exchanger and an intravascular heat exchange catheter is described. The system includes a two stage cooling system providing for a high rate of cooling in one stage and a lower rate of cooling in a second stage. Both stages may be used to provide maximal cooling while the second stage is used to provide improved control of the cooling rate as a target temperature is approached. The second stage may also be used to provide heat to the heat exchange fluid.
