Claims
- 1. A method for improving cardiovascular parameters in a patient undergoing a medical procedure under general anesthesia, comprising:(a) contacting a substantial portion of the patient's external body surface, without covering the areas where surgical procedures are performed with a heat exchanger which can transfer heat to or absorb heat from the body surface; (b) continuously measuring parameters from the body including at least the actual body core temperature (aBCT) and determining a parameter indicative of the heat transfer dynamics (HTD) between the body's periphery and the body's core; and (c) in a processor, receiving data signals corresponding to the measured parameters and to the determined HTD, comparing the aBCT with a desired body core temperature (dBCT) needed in order to maintain desired cardiovascular parameters based on the aBCT/dBCT difference, and emitting a control signal to control heat transfer properties of said heat exchanger.
- 2. A method according to claim 1, wherein the heat transfer to and from the body portion is achieved by transfer of heat control fluid through said heat exchanger.
- 3. A method according to claim 1, comprising continuously monitoring temperature at a skin portion proximal to a skin portion in which the heat exchanger is applied, and determining said HTD based on the rate of temperature change at said skin portion.
- 4. A method according to claim 1, wherein said heat exchanger is in a form of a garment to be worn over a portion of the body.
- 5. A method according to claim 4, having adhesive patches or flaps at edges of the garment to permit fixing of the garment to the body of the patient.
- 6. A method according to claim 4, wherein said garment comprises at least two layers defining between them a fluid transfer space for transfer of heat control fluids therethrough.
