Abstract:
PROBLEM TO BE SOLVED: To provide a system to treat sepsis or septic shock.SOLUTION: The system comprises: a heat exchange catheter; a heat exchange fluid circulation device; and a controller, each of which is configured to cool or warm the temperature of all or a portion of the body of a human or animal subject to treat sepsis or septic shock which can result in shock, hypoxia, ischemia and/or multiple organ failure in human or animal subjects.
Abstract:
PROBLEM TO BE SOLVED: To promote effective application of CPR (cardiopulmonary resuscitation) by performing the measurement and indication of chest compression.SOLUTION: A displacement detector produces a displacement indication signal indicative of the displacement of the chest toward the CPR recipient's spine. A signaling mechanism provides chest compression indication signals directing a chest compression force being applied to the chest and a frequency of such compressions. An automated controller and an automated constricting device may be provided for applying CPR to the recipient in an automated fashion. The automated controller receives the chest compression indication signals from the signaling mechanism, and, in accordance with the signals, controls the force and frequency of constrictions. A system may be provided with a tilt compensator comprising a tilt sensor mechanism outputting a tilt compensation signal indicative of the extent of tilt of the device, and may be further provided with an adjuster for adjusting the distance value in accordance with the tilt compensation signal. An ECG signal processor may be provided which removes the CPR-induced artifact from a measured ECG signal obtained during the administration of CPR.
