SYSTEMS AND METHODS FOR MONITORING, MANAGING, AND PREVENTING FATIGUE DURING VENTILATION
First Claim
Patent Images
1. A method for ventilating a patient with a ventilator comprising:
- monitoring a plurality of fatigue indicators;
establishing a baseline for the fatigue indicators;
determining a change from the baseline based on the monitored fatigue indicators;
comparing the change to a corresponding fatigue threshold;
detecting respiratory fatigue based on the step of comparing the change to the fatigue threshold; and
displaying a fatigue notification after the step of detecting respiratory fatigue.

14. A ventilator system comprising:
-
a pressure generating system adapted to generate a flow of breathing gas; a ventilation tubing system including a patient interface for connecting the pressure generating system to a patient; a plurality of sensors operatively coupled to at least one of the pressure generating system, the patient, and the ventilation tubing system, wherein the plurality of sensors monitor a plurality of parameters to generate sensor output; a baseline module determines a baseline for a plurality of fatigue indicators and determines a change in the fatigue indicators from the baseline based on the sensor output; a fatigue module compares the change to corresponding fatigue thresholds and determines that the patient is fatigued based on the comparisons; a notification module determines an appropriate notification; and a graphical user interface displays the appropriate notification received from the notification module, wherein the appropriate notification message notifies a clinician that the fatigue module determined that the patient is fatigued. - View Dependent Claims (15, 16, 17, 18, 19)

20. A computer-readable medium having computer-executable instructions for performing a method of ventilating a patient with a ventilator, the method comprising:
-
repeatedly monitoring a plurality of fatigue indicators; repeatedly establishing a baseline for the fatigue indicators; repeatedly determining a change from the baseline based on the monitored fatigue indicators; repeatedly comparing the change to a fatigue threshold; detecting respiratory fatigue based on the step of comparing the change to the fatigue threshold; and displaying a fatigue notification after the step of detecting respiratory fatigue.
