Abstract

A treatment system delivers a breathing gas and frozen ice or other particles (FSP) to a bronchus of a lung of a patient in order to induce hypothermia. The breathing gas and the FSP are usually delivered through separate lumens. Clogging of an FSP lumen can be inhibited by heating and/or cooling of the lumen. The temperature of exhaled gases or a body temperature may be measured, and a controller can adjust the duration or rate at which the ice particles are delivered in order to control the patient's core temperature based on the measured temperature.
