  • Patent number: 5121470
    Abstract: An automated interactive record system for automatically indexing a set of data obtained from a number of internal and external input sources. A set of data is organized along at least one indexing dimension. Specific data events are identified from the set of data according to predetermined methods. An index of data objects associated with the specific data events is then established. The index of data objects is then displayed along the indexing dimension and actuators are defined for manipulating the data objects that are associated with specific data events.

  • Patent number: 4676252
    Abstract: Patient monitoring method and apparatus for measurement of in vivo extra vascular lung water (pulmonary edema) and pulmonary circulatory system thermal bypass utilizing double indicator dilution with temperature and electrical conductivity modifiers. A thermal modifier is utilized for a primary indicator dilution measurement with electrical conductivity provided as a reference indicator which in turn is corrected for temperature effects produced by the thermal moderator as well as effects of plasma characteristics. Thermal and conductivity sensors are both placed upstream and downstream of the lungs in the pulmonary artery and thesystemic arterial system, and a thermal and conductivity moderator is injected at a site upstream from both. Temperature and conductivity are detected at both sites and the conductivity signal is converted to a volume dilution valve.
