Systems and methods for estimating hemodynamic parameters from a physiological curve image

摘要

Systems and methods for estimating hemodynamic parameters from physiological curve images. A mobile device captures pictures of a physiological monitor display, which are used to extract the relevant physiological curve and upload it to an analysis server for processing and estimation of hemodynamic parameters. In some examples, the mobile device runs a dedicated application and is Internet-connected, which in turn connects to an Internet-connected analysis server. In some further examples, the system can be implemented using any computer that is capable of taking an image, extracting a physiological curve, and uploading it to a network service for analysis. In still further examples, analysis can be performed by the mobile device instead of via a remote server.

主权项

1. A system for flow-based hemodynamic monitoring, comprising:
a display device configured to visually display a physiological curve of a patient, the physiological curve comprising either a pulse pressure curve or a plethysmographic curve; a capture device comprising:
a camera configured to capture the visual display of the physiological curve of the patient;capture storage media containing a capture set of instructions configured to be executed by the capture device, the capture set of instructions including instructions for enabling a user to manually extract an extracted portion of the visual display containing the physiological curve from the visual display; anda capture communication device configured to transmit and receive image information, the image information including the extracted portion of the visual display portion containing the physiological curve; and an analysis device configured to analyze the extracted portion of the visual display containing the physiological curve transmitted from the capture device to determine one or more hemodynamic parameters.
