Experimental setup. Warmed or chilled fluid was run through the warming cartridge at a rate determined by the peristaltic pump. Temperature was measured before and after the warming cartridge. A denotes the location of the temperature sensor for the parylene-coated enFlow experiments (0.635 cm); B denotes the location of the temperature probe for the uncoated enFlow experiments (between 10 and 20 cm). Data was routed to a laptop computer for analysis. Fluid was recycled back into the chiller after infusion
