Abstract
A novel clinical decision support system (CDS) helps the clinician setup, maintain, and interpret esophageal pressure measurement. The esophageal pressure CDS (Pes CDS) would remind the clinician to do an occlusion test whenever the balloon is first inserted or changes dramatically. It could monitor the occlusion test and provide feedback on the performance and success of the occlusion test. Changes in the patient or monitored data can be tracked by looking for changes in the balloon baseline pressure, changes in the amplitude of the pressure waveform, or changes in the pattern of the Pes waveform. Having information from the ventilator will further increase the ability of the system to determine when Pes is changing unexpectedly.
Core Innovation
The disclosed invention provides a ventilator-related system and associated method in which two or more sensors provide measurement data for esophageal pressure data, airway pressure data, and airway flow data from a patient being ventilated. A processor electronically coupled to the sensors receives the measurement data and continuously compares the esophageal pressure data with changes to both the airway pressure data and the air flow data to determine an accuracy of the esophageal pressure data.
The disclosed arrangement is directed to improving operation of a ventilator by continuously determining an accuracy and reliability of esophageal pressure data using comparisons to airway pressure and airway flow changes. It includes a display interface that automatically presents an accuracy indicator corresponding to the reliability of the esophageal pressure data, thereby supporting whether the esophageal pressure measurement can be relied upon during ventilation.
Claims Coverage
The independent claims present 3 independent claim forms: a ventilator system, a method, and a computer program product. They share the same core workflow of accessing measurement data for esophageal pressure, airway pressure, and airway flow; continuously comparing changes in esophageal pressure with changes in airway pressure and airway flow to determine accuracy; and displaying an automatic accuracy indicator of reliability of the esophageal pressure data.
Multi-sensor esophageal pressure, airway pressure, and airway flow measurement for accuracy determination
Two or more sensors provide measurement data for esophageal pressure data, airway pressure data, and airway flow data from a patient being ventilated.
Continuous comparison to determine esophageal pressure data accuracy
A processor electronically coupled to the sensors continuously compares the esophageal pressure data with changes to both the airway pressure data and the air flow data to determine an accuracy of the esophageal pressure data.
Automatic accuracy indicator for reliability display
Displaying, on a display, an automatic accuracy indicator to indicate a reliability of the esophageal pressure data.
Access, compare, and display reliability in a ventilator operation method
A method that accesses measurement data from two or more sensors for esophageal pressure data, airway pressure data, and airway flow data; continuously compares the esophageal pressure data with changes to each of the airway pressure data and the air flow data to determine an accuracy of the esophageal pressure data; and displays an automatic accuracy indicator to indicate a reliability of the esophageal pressure data.
Computer program product performing the access, compare, and display functions
A computer program product that causes a computing device to access measurement data from two or more sensors for esophageal pressure data, airway pressure data, and airway flow data; continuously compare the esophageal pressure data with changes to each of the airway pressure data and the air flow data to determine an accuracy of the esophageal pressure data; and display an automatic accuracy indicator to indicate a reliability of the esophageal pressure data.
Across the independent claim set, the inventive concept is the use of multiple sensors and a processor to continuously compare esophageal pressure data with changes in airway pressure and airway flow to determine an accuracy, and to display an automatic accuracy indicator reflecting the reliability of the esophageal pressure data.
Stated Advantages
Improves operation of a ventilator by providing an automatic accuracy indicator indicating reliability of esophageal pressure data.
Documented Applications
Used during ventilation to provide reliability of esophageal pressure data via a display-based automatic accuracy indicator.
Support for ventilator-related clinical decision support status by displaying reliability of esophageal waveform data (including warnings and automatic color coding as described in the dependent claim set).
