Abstract

A patient carestation for providing care to a patient including at least one environmental sensor sensing information concerning the environment surrounding the patient and providing electronic signals indicative of that environment. There are also physiological sensors sensing information relating to physiological conditions of the patient other than skin temperature and providing electronic signals indicative of physiological conditions of the patient. There may also be therapeutic sensors providing data based on therapy administered by peripheral apparatus and an input receiving patient information. A signal processor receives the signals from the physiological sensors, the environmental sensor, the therapeutic sensor and the patient information input and combines those signals into an integrated combination of signals for use by the caregiver. The integrated combination of signals can be used in a smart alarm or to generally appraise the caregiver at a central location as to the status of the patient.
