Abstract
Systems and methods for determining patient fatigue during ventilation of a patient are described. Novel notification and/or management of patient fatigue during ventilation are described. Further, system and methods for preventing diaphragm fatigue or weakness are described.
Claims20
A method for ventilating a patient with a ventilator comprising:
- monitoring at least one fatigue indicator for a period of time during a spontaneous mode of ventilation;
- determining a change in the at least one fatigue indicator;
- detecting respiratory fatigue when the change breaches a fatigue threshold;
- and
- in response to detecting respiratory fatigue, switching from the spontaneous mode of ventilation to a mandatory mode of ventilation.
2 more elements
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;
- and
- a memory storing computer-executable instructions that, when executed by a processor, cause the ventilator system to:
- monitor at least one fatigue indicator for a period of time during a spontaneous mode of ventilation;
- determine a change in the at least one fatigue indicator;
- detect respiratory fatigue when the change breaches a fatigue threshold;
- and
- in response to detecting respiratory fatigue, switch from the spontaneous mode of ventilation to a mandatory mode of ventilation.
6 more elements
A computer-readable medium having computer-executable instructions that, when executed by a processor, cause a ventilator system to:
- monitor at least one fatigue indicator for a period of time during a spontaneous mode of ventilation;
- establish a baseline for the at least one fatigue indicator;
- compare at least one monitored value for the at least one fatigue indicator to the baseline to determine the change in the at least one fatigue indicator;
- detect respiratory fatigue when the change breaches a fatigue threshold;
- and
- in response to detecting respiratory fatigue, switch from the spontaneous mode of ventilation to a mandatory mode of ventilation.
