APPARATUS FOR DETERMINING AN INDICATOR REPRESENTATIVE FOR A FLUID RESPONSIVENESS PARAMETER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18039580 titled 'APPARATUS FOR DETERMINING AN INDICATOR REPRESENTATIVE FOR A FLUID RESPONSIVENESS PARAMETER

Simplified Explanation

The invention relates to an apparatus for determining a fluid responsiveness parameter based on pulse signals measured over subsequent respiratory cycles.

  • Accelerated fitting process:
   - Reduce the number of data values before fitting
   - Determine initial fit parameter value based on data characteristics or previous fitting
   - Carry out fitting in several stages, increasing data values used from stage to stage
    • Potential Applications:**

This technology can be used in medical settings to quickly and accurately determine fluid responsiveness in patients, aiding in the management of conditions such as sepsis, shock, and heart failure.

    • Problems Solved:**

This technology solves the problem of time-consuming and complex fitting processes for determining fluid responsiveness parameters, allowing for faster and more efficient patient care.

    • Benefits:**

- Quick and accurate determination of fluid responsiveness - Improved patient management in critical conditions - Enhanced efficiency in medical decision-making

    • Potential Commercial Applications: Accelerated Fitting Process for Determining Fluid Responsiveness Parameter**

This technology can be applied in hospitals, emergency rooms, and intensive care units to improve patient care and outcomes by quickly assessing fluid responsiveness in critically ill patients.

    • Possible Prior Art:**

Previous methods for determining fluid responsiveness parameters may have involved manual calculations or less efficient fitting processes, leading to delays in patient care and decision-making.

    • Unanswered Questions:**

1. How does this technology compare to existing methods in terms of accuracy and reliability? 2. Are there any limitations or potential challenges in implementing this accelerated fitting process in clinical practice?


Original Abstract Submitted

The invention relates to an apparatus for determining an indicator that is representative of a fluid responsiveness parameter. The indicator is determined based on a fitting of a functional prototype to data values (s) determined from pulse signals measured over subsequent respiratory cycles. The fitting process is accelerated by a) reducing the number of data values before fitting, b) determining an initial fit parameter value for the functional prototype based on characteristics of the data values and/or a fit parameter value known from a previous fitting, and/or c) carrying out the fitting in several stages, wherein the number of data values used is increased from stage to stage and a fit parameter value determined in a previous stage is used as initial fit parameter value in a current stage. This allows for a faster determination of the fluid responsiveness parameter.
