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.
Claims41
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;
- compute estimates, based on the received arterial blood pressure measurements, of heart rate, total peripheral resistance, cardiac output, ejection fraction, and ventricular end-diastolic volume;
- and
- select a type of circulatory shock, from a plurality of types of circulatory shock, based on the computed mean arterial blood pressure and the computed estimates.
