Abstract:
A method of heat exchange within the lungs of a mammal, comprising:a. delivering a first volume of oxygenated liquid to the lungs in an amount approximately equal to the functional residual capacity of the lungs, said oxygenated liquid having a temperature below the temperature of the mammal; b. cycling a second volume of oxygenated liquid into and out of the lungs in an amount less than one third of total lung capacity and at a liquid cycle rate defined by delivering said second volume of oxygenated liquid at a rate of 6 mL/kg/min to 50 mL/kg/min, then removing said second volume of oxygenated liquid at a rate of 12 mL/kg/min to 80 mL/kg/min; and c. cycling a volume of breathing gas into and out of the lungs at a predetermined gas cycle rate which is independent of the liquid cycle rate.
