Abstract
During therapeutic hypothermia for post-cardiac arrest syndrome (PCAS) patients, physiological monitors including respiro-circulatory, thermometric and cerebral functions are requisite. We need to recognize the physiological changes during therapeutic hypothermia:a direct cardiac depression, sympathetic augmentation or disturbances in the peripheral circulation. Especially for PCAS patients from cardiogenic CPAs, the early percutaneous coronary intervention and/or intra-aortic balloon pumping should be considered. In the future, we need to develop certain monitors for evaluating the effects of treatments done during therapeutic hypothermia not only on the respiro-circulatory, but also on the cerebral functions in the clinical settings.
