  • Patent number: 9332911
    Abstract: Systems and methods for prediction and detection of circulatory shock using estimates or measurements of arterial blood pressure, heart rate, stroke volume, cardiac output, total peripheral resistance, cardiac ejection fraction, cardiac contractility and ventricular end-diastolic volume are provided. These estimates and measurements are used to determine a type of circulatory shock. In some embodiments, the type of circulatory shock is determined to be one of septic shock, hypovolemic shock, anaphylactic shock, hemorrhagic shock, and cardiogenic shock.
    Type: Grant

  • Patent number: 3945401
    Abstract: A quick acting three-way valve that operates a poppet with a lost motion connection. A sleeve is sealed through the diaphragm. A solid or hollow sleeve may be employed with a hollow or solid poppet, respectively. If either the sleeve or the poppet is hollow, the other may or may not be, as desired. An exhaust port is provided in communication with either one or both of the hollow interiors of the sleeve and poppet, the exhaust port being provided through the valve body.
