1. A liquid ventilation system comprising:
a reservoir holding a perfluorochemical (PFC) fluid, and a heat exchanger downstream from the reservoir;
an appliance configured to be disposed within a patient, the appliance coupled in fluid communication downstream from the reservoir;
a sensor in the appliance configured to measure an intra-lung pressure;
an injector configured to supply the PFC fluid through the appliance in response to measurements of the intra-lung pressure from the sensor;
a pressure regulator configured to maintain a pressure of the fluid at the injector;
an exchanger-regulator line from the heat exchanger to the pressure regulator;
an administration line from the pressure regulator to the injector;
a recirculation line from the pressure regulator to the reservoir; and
the pressure regulator is arrangeable between a first position enabling fluid communication from the heat exchanger to the injector and disabling fluid communication from the heat exchanger to the reservoir and a second position enabling fluid communication from the heat exchanger to the reservoir and disabling fluid communication from the heat exchanger to the injector.
