Patent ID: 8909330

Claim:
A system for processing at least one vital sign from a patient and generating an alarm, the system comprising: a first sensor comprising a first detector worn on the patient's body and configured to detect a first time-dependent physiological waveform indicative of one or more contractile properties of the patient's heart; a second sensor comprising a second detector worn on the patient's body and configured to detect a second time-dependent physiological waveform indicative of one or more contractile properties of the patient's heart; a first motion-detecting sensor positioned on a first location on the patient's body, the motion-detecting sensor configured to generate a first set of time-dependent motion waveforms indicative of motion of the location on the patient's body to which it is affixed; a processing component configured to be worn on the patient's body, the processing component comprising: a second motion-detecting sensor positioned on a second location on the patient's body, the second motion-detecting sensor configured to generate a second set of time-dependent motion waveforms indicative of motion of the location on the patient's body to which the processing component is affixed; and a microprocessor configured to receive the time-dependent physiological waveforms and at least of portion of the first and second set of time-dependent motion waveforms and continuously monitor therefrom: (i) the patient's blood pressure and heart rate calculated using the first and second time-dependent physiological waveforms; (ii) the patient's posture, activity state, and degree of motion, calculated using the first set of motion waveforms and the second set of motion waveforms and (iii) an alarm condition, determined by collectively processing the patient's blood pressure, the patient's heart rate, and the patient's posture, activity state, and degree of motion with an alarm algorithm and determining therefrom if one or more alarm criteria have been met, wherein the alarm algorithm is configured to continuously adjust the one or more alarm criteria according to the patient's posture, activity state, and degree of motion by setting an alarm criterion for the patient's heart rate which reflects the patient's activity state, and setting an alarm criterion for the patient's blood pressure which reflects the patient's posture and degree of motion.
