摘要:
The present invention provides a method and apparatus for controlling a patient's body temperature and in particular for inducing therapeutic hypothermia. Various embodiments of the system are described. The system includes: a source of breathing gas, which may be in the form of a compressed breathing gas mixture; a heat exchanger or other heating and/or cooling device; and a breathing interface, such as a breathing mask or tracheal tube. Optionally, the system may include additional features, such as a mechanical respirator, a nebulizer for introducing medication into the breathing gas, a body temperature probe and a feedback controller. The system can use air or a specialized breathing gas mixture, such as He/O.sub.2 or SF/O.sub.2 to increase the heat transfer rate. In addition, the system may include an ice particle generator for introducing fine ice particles into the flow of breathing gas to further increase the heat transfer rate.

摘要:
Peritoneal heat exchange provides the benefit of extremely rapid cooling of the patient's target organs such as the heart and brain as well as facilitating global patient body temperature reduction to therapeutically effective temperatures. The heat exchange medium of the present invention is a chilled gaseous fluid suspension of frozen ice particles.

摘要:
A therapeutic treatment system has a delivery device is adapted to deliver a cooled breathing gas mixture to a patient and an injection device positioned near a distal end of the delivery device. The injection device is coupled to a source of liquid. The treatment system also includes a control system coupled to the delivery device and the injection device. Alternatively, the control system is adapted to control the injection device to release a fluid into the cooled breathing gas mixture to form a frozen mist of fine ice particles in the cooled breathing gas mixture.
