Claim 0:
1. A portable system for managing the temperature of a patient during transport, comprising:
a heater/cooler configured to be in fluid communication with a heat transfer surface pad or a heat transfer catheter configured for insertion into a patient;
a refrigeration circuit having a compressor configured to cool a heat exchange fluid circulating between the heater/cooler and the heat transfer surface pad or heat transfer catheter;
a pump for circulating heat exchange fluid between the heater/cooler and the heat transfer catheter or surface pad;
an alternating current power supply configured to provide power to the system when the alternating power supply is connected to a source of alternating current;
a processor configured to monitor the alternating current power supply and to cause an indication to be displayed on an indicator on a console if the alternating current power supply connection to the source of alternating current is interrupted;
wherein the system is configured to be connected to at least one rechargeable battery, the at least one rechargeable battery configured to provide power to the system when the alternating power supply is not connected to a source of alternating current;
wherein the at least one rechargeable battery is capable of powering the system such that the system can deliver at least 50 watts of cooling power;
wherein if the system is powered on and wherein the connection to the alternating current source is interrupted, the system automatically switches to receiving power from the at least one rechargeable battery;
wherein the processor, responsive to the interruption of the connection to the alternating current source, transmits a signal to the indicator to alert an operator of the system to the interruption of the connection to the alternating current source and also provides an indication to the operator of the amount of energy remaining in the at least one rechargeable battery,
wherein the alternating current power supply has a direct current output used to charge the at least one rechargeable battery, wherein the processor monitors a current draw on the direct current output, the processor adjusting the current to charge the battery in accordance with the power needs of the console so as to limit the current draw from the direct current output to the battery, and
wherein when the alternating current power supply connection to the source of alternating current is interrupted, the processor adjusts the speed of the compressor of the refrigeration circuit, while maintaining an operation of the pump for circulating heat exchange fluid between the heater/cooler and the heat transfer surface pad or heat transfer catheter.
