A method and system for infusing medical liquid with gasses, the systemcomprising a gas source, a vacuum pump, atemperature-controlled container including a fluid reservoir coupled to thegas source and the vacuum pump, a heating and coolingsystem, and a sonicator, and a controller configured to de-gas a liquid in thefluid reservoir by activating the vacuum pump, re-gasthe liquid in the fluid reservoir by releasing gas from the gas source to thefluid reservoir via a first fluid line, and deliver there-gassed liquid from the fluid reservoir to a catheter via a second fluidline.
