  • Publication number: 20250032040
    Abstract: Microcirculation assessment systems and methods for determining a systemic response of a patient which may be related to sepsis. A microcirculation assessment device coupled with a patient obtains a microcirculation assessment of the patient. System logic applies an algorithm to the microcirculation assessment to indirectly determine the systemic response. Artificial intelligence and/or machine learning logic collects microcirculation assessment data and corresponding actual systemic responses to define the algorithm that correlates microcirculation assessment with systemic response. System logic may recommend a therapy based the systemic response. System logic may also govern the operation of therapy equipment to deliver a therapy. The microcirculation assessment device may utilize any suitable technology to obtain the microcirculation assessment, such as ultrasound, video capillaroscopy, or thermal imaging, for example.
