First Claim
Patent Images
1. A system for predicting or detecting circulatory shock, comprising:
- a blood pressure measuring device;
a processor;
a display;
a user interface; and
a memory storing computer-executable instructions, which when executed by the processor cause the processor to;
receive measurements of arterial blood pressure from the blood pressure measuring device;
compute mean arterial blood pressure from the received arterial blood pressure measurements;
receive or compute estimates of at least one of heart rate, total peripheral resistance, stroke volume, cardiac output, ejection fraction, ventricular end-diastolic volume, and cardiac contractility;
predict or detect a type of circulatory shock based in part on one or more of the received measurements and the received or computed estimates.

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.
