Abstract

A multimode ventilator is disclosed that provides physicians and clinicians the ability to select multiple modes of operation for the ventilator. Embodiments of the present disclosure provide users with the ability to select from multiple modes of ventilator operations. The users may also set transition conditions and monitoring thresholds that determine when the multimode ventilator transitions between the selected modes of operations. Multiple user interfaces are also disclosed that allow the user to interact with the multimode ventilator in order to select particular modes of operation, transition conditions, and monitoring thresholds.

Claims

1. A method for transitioning between a first mode of ventilator operation and a second mode of ventilator operation, the method comprising:

providing a plurality of first modes of ventilator operations and a plurality of second modes of ventilator operations;

receiving a selection of the first mode of ventilator operation;

receiving a selection of the second mode of ventilator operation;

initiating ventilation of a patient in the first mode of ventilator operation;

monitoring the ventilation of the patient; and

transitioning into the second mode of ventilator operation.

2. The method of claim 1, further comprising receiving one or more conditions operable to initiate the transition between the first mode of ventilator operation and the second mode of ventilator operation.

3. The method of claim 2, further comprising receiving one or more conditions operable to initiate the transition between the second mode of ventilator operation and the first mode of ventilator operation.

4. The method of claim 2, further comprising collecting monitored data from the patient.

5. The method of claim 4, further comprising comparing the monitored data against the received conditions.

6. The method of claim 5, wherein the step of transitioning into the second mode of ventilator operation is based on the comparing of the monitored data against the received conditions.

7. The method of claim 1, further comprising generating a user interface for displaying the plurality of first and second modes of ventilator operations.

8. The method of claim 7, wherein the user interface displays notification informing the user of a transition between the first mode and the second mode of operations.

9. A method for transitioning between a first mode of ventilator operation and a second mode of ventilator operation, the method comprising:

providing a plurality of first modes of ventilator operations and a plurality of second modes of ventilator operations;

receiving a selection of the first mode of ventilator operation;

receiving a selection of the second mode of ventilator operation;

receiving a first selection of first transition conditions operable to initiate the transition between the first mode of ventilator operation and the second mode of ventilator operation;

initiating ventilation of a patient in the first mode of ventilator operation;

monitoring the ventilation of the patient; and

transitioning into the second mode of ventilator operation based on detection of the first transition conditions.

10. The method of claim 9, wherein the first transition conditions comprises one of:

an FIO₂ percentage;

an end-tidal CO₂ level;

a P100 level;

an S_PO₂ level;

a Minute Ventilation requirement; and

a respiratory rate criteria.

11. The method of claim 9, wherein the first transition condition specifies when the ventilator transitions from the first mode of operation to the second mode of operation.

12. The method of claim 9, further comprising receiving a second selection of a second transition condition.

13. The method of claim 12, wherein the second transition condition specifies when the ventilator transitions from the second mode of operation to the first mode of operation.

14. The method of claim 12, wherein the second transition condition comprises one of:

a respiration rate;

an end-tidal CO level;

a minimum threshold of spontaneous effort; and

an airflow rate.

15. The method of claim 9, further comprising providing a plurality of monitoring thresholds.

16. The method of claim 15, further comprising receiving a selection of a first monitoring threshold.

17. The method of claim 16, further comprising receiving an association between the first monitoring threshold and the first transition condition.

18. A computer storage medium encoding computer-readable instructions executable by a processor for performing a method of transitioning between a mandatory mode of ventilator operation and a spontaneous mode of ventilator operation during the operation of a ventilator on a patient, the method comprising:

providing a plurality of mandatory modes of ventilator operation for selection by a user;

proving a plurality of spontaneous modes of ventilator operation for selection by the user;

providing one or more mode transition conditions;

receiving, from the user, a selection of a first mandatory mode of ventilator operation from the plurality of mandatory modes, a selection of a first spontaneous mode of ventilator operation from the plurality of spontaneous modes, and a selection of a first transition condition and a second transition condition;

operating the ventilator in the selected first mandatory mode of ventilator operation;

monitoring the ventilation of the patient;

transitioning operation of the ventilator from the selected first mandatory mode of ventilator operation to the selected first spontaneous ventilator operation if the first transition condition is met.

19. The computer storage medium claim 18, wherein the first transition condition specifies when the ventilator should transition from the first mandatory mode to the first spontaneous mode, and wherein the second transition condition specifies when the ventilator should transition back from the first spontaneous mode to the first mandatory mode.

20. The computer storage medium of claim 18, further comprising receiving, from the user, a selection of a first monitoring threshold,

21. The computer storage medium of claim 20, wherein the first monitoring threshold is associated with the first transition condition.
