Abstract

A method for delivering ventilatory support to a patient is presented. The method includes controlling delivery of a first backup breath by delaying onset of the first backup breath, wherein delaying the onset of the first backup breath is configured to allow selection of an appropriate backup rate. Systems and computer-readable medium that afford functionality of the type defined by this method is also contemplated in conjunction with the present technique.

Claims

1. A method for delivering ventilatory support to a patient, the method comprising:

controlling delivery of a first backup breath by delaying onset of the first backup breath, wherein delaying the onset of the first backup breath is configured to allow selection of an appropriate backup rate.

2. The method of claim 1, wherein the patient is operationally coupled to a ventilation system.

3. The method of claim 2, wherein the patient is operationally coupled to the ventilation system via an invasive interface, a non-invasive interface, or a combination thereof.

4. The method of claim 1, further comprising monitoring a breathing pattern of the patient.

5. The method of claim 4, further comprising measuring a first time interval between two consecutive previous breaths.

6. The method of claim 5, wherein delaying the onset of the first backup breath comprises postponing commencement of the first backup breath based upon the measured first time interval.

7. The method of claim 6, further comprising comparing the first time interval with a predetermined threshold.

8. The method of claim 7, wherein the predetermined threshold comprises a backup rate.

9. The method of claim 7, further comprising delaying the onset of the first backup breath if the measured first time interval exceeds the predetermined threshold.

10. The method of claim 6, wherein postponing commencement of the first backup breath comprises delaying the onset of the first backup breath by up to two times the predetermined threshold.

11. A system for delivering ventilatory support to a patient, the system comprising:

a ventilation system configured to provide artificial respiration to the patient, wherein the ventilation system is operationally coupled to the patient via a patient interface; and

a backup breath delivery module configured to automatically control delivery of a first backup breath by delaying onset of the first backup breath, wherein delaying the onset of the first backup breath is configured to allow selection of an appropriate backup rate.

12. The system for delivering ventilatory support to a patient of claim 11, wherein the backup breath delivery module is further configured to:

monitor a breathing pattern of the patient;

measure a first time interval between two consecutive previous breaths; and

compare the first time interval with a predetermined threshold; and

postpone commencement of the first backup breath based on the measured first time interval.

13. The system for delivering ventilatory support to a patient of claim 12, wherein the backup breath delivery module is configured to postpone commencement of the first backup breath by delaying onset of the first backup breath by up to two times the predetermined threshold.

14. A computer readable medium comprising one or more tangible media, wherein the one or more tangible media comprise:

code adapted to control delivery of a first backup breath by delaying onset of the first backup breath, wherein delaying the onset of the first backup breath is configured to allow selection of an appropriate backup rate.

15. The computer readable medium, as recited in claim 14, further comprising code adapted to monitor a breathing pattern of the patient.

16. The computer readable medium, as recited in claim 15, further comprising code adapted to measure a first time interval between two consecutive previous breaths.

17. The computer readable medium, as recited in claim 16, wherein the code adapted to delay the onset of the first backup breath comprises code adapted to postpone commencement of the first backup breath based upon the measured first time interval.

18. The computer readable medium, as recited in claim 17, further comprising code adapted to compare the first time interval with a predetermined threshold.

19. The computer readable medium, as recited in claim 18, further comprising code adapted to delay the onset of the first backup breath if the measured first time interval exceeds the predetermined threshold.

20. The computer readable medium, as recited in claim 17, wherein code adapted to postpone commencement of the first backup breath comprises code adapted to delay the onset of the first backup breath by up to two times the predetermined threshold.
