  • Publication number: 20230197282
    Abstract: Data streams are received from each of the plurality of sensors. These data streams comprise varying values generated by the sensors and characterize an associated physiological parameter. A parameter score is repeatedly determined for each physiological sensor that is based on whether the varying values for the associated physiological parameter deviate from at least one pre-defined threshold. A patient health index is repeatedly generated by combining each of the determined parameter scores to characterize an overall health of the patient. Data characterizing the patient health index is repeatedly provided. Related apparatus, systems, techniques and articles are also described.

  • Patent number: 8374691
    Abstract: Validated atrial and/or ventricular interval decreases are used to discriminate between VT and SVT. Atrial and/or ventricular intervals are monitored in order to detect decreases in such intervals (which are indicative in increases in rate). The atrial intervals can be, e.g., AA intervals, and the ventricular intervals can be, e.g., VV intervals. A detected atrial and/or ventricular interval decrease can be a decrease that is greater than an interval decrease threshold. Detected atrial and/or ventricular interval decreases can be validated by examining atrial and/or ventricular intervals before and after a detected atrial and/or ventricular interval decrease. The use of the validated atrial and/or ventricular interval decreases to classify an arrhythmia as SVT or VT can be called arrhythmia initiation analysis, since it is believed to determine whether the initiation of the arrhythmia is in an atrium or a ventricle.

  • Patent number: 8172765
    Abstract: The invention relates to a method of assessing airway variability in airway responsiveness or asthma by measuring the variation of resistance (Rrs) by a forced oscillation technique utilizing either a single or a plurality of input frequencies during a plurality of respiratory cycles of a patient; calculating the statistical variability of the Rrs for the patient; and, correlating the statistical variability of the Rrs of the patient to a standard curve to quantify the degree of asthma of the patient. The invention also enables the effectiveness of a bronchoactive agent to be measured.
