Abstract

A medical system (100) is disclosed that provides a respiratory-based control of at least one medical procedure. In this regard, the medical system (100) includes one or more appropriate sensors (108) for providing respiratory data on a patient (104). This respiratory data is utilized by respiration assessment logic (116) to determine if the respiratory data has exceeded one or more respiration thresholds and which may be equated with a “sudden” respiratory event. Identification of such a sudden respiratory event by the logic (116) results in the suspension of the noted medical procedure. Patient respiration data may also be displayed, for instance in a color that depends upon its magnitude or level.

First claim

What is claimed is:

1. A respiratory assessment system for use in connection with a cardiac navigation and/or visualization system, the respiratory assessment system comprising:
a respiration assessment logic implemented in at least one of hardware and a non-transitory computer readable medium having embodied thereon computer-readable code, wherein the respiration assessment logic is configured to:
receive current patient respiration data from the cardiac navigation and/or visualization system as input;
evaluate the current patient respiration data to identify whether a sudden respiratory event exists; and
suspend a medical procedure of the cardiac navigation and/or visualization system when the respiration assessment logic identifies that the sudden respiratory event exists.

2. The respiratory assessment system according to claim 1 , wherein the current patient respiration data from the cardiac navigation and/or visualization system comprises electrophysiological data.

3. The respiratory assessment system according to claim 2 , wherein the electrophysiological data comprises impedance data.

4. The respiratory assessment system according to claim 3 , wherein the respiration assessment logic is configured to evaluate an amplitude of the impedance data to identify whether the sudden respiratory event exists.

5. The respiratory assessment system according to claim 1 , wherein the sudden respiratory event is representative of a current patient respiration that is outside of a preset respiration range.

6. The respiratory assessment system according to claim 5 , wherein the preset respiration range is adjustable.

7. The respiratory assessment system according to claim 1 , wherein the sudden respiratory event is representative of a current patient respiration that exceeds at least one respiration threshold.

8. A respiratory assessment and control module for use in performing a cardiac medical procedure, the respiratory assessment and control module comprising:
a non-transitory computer readable medium having embodied thereon computer readable respiration assessment code that, when executed by a computer or processor, causes the computer or processor to:
receive electrophysiological data from at least one sensor;
evaluate the electrophysiological data to determine a current respiratory condition of a patient; and
when determined that the current respiratory condition of the patient comprises a sudden respiratory event, suspend a medical procedure of a medical device.

9. The respiratory assessment and control module according to claim 8 , wherein the electrophysiological data comprises impedance data.

10. The respiratory assessment and control module according to claim 9 , wherein the non-transitory respiration assessment code, when executed by the computer or processor, further causes the computer or processor to evaluate an amplitude of the impedance data to determine the current respiratory condition of the patient.

11. The respiratory assessment and control module according to claim 8 , wherein the sudden respiratory event is representative of a current respiratory condition of the patient that is outside of a preset respiration range.

12. The respiratory assessment and control module according to claim 11 , wherein the preset respiration range is adjustable.

13. The respiratory assessment and control module according to claim 8 , wherein the sudden respiratory event is representative of a current respiratory condition of the patient that exceeds at least one respiration threshold.

14. A respiratory assessment system for use in connection with a cardiac navigation and/or visualization system configured for generating a map containing electrophysiology data, the respiratory assessment system comprising:
a respiration assessment logic implemented in at least one of hardware and a non-transitory computer readable medium having embodied thereon computer-readable code, wherein the respiration assessment logic is configured to:
receive current patient respiration data as input;
compare the current patient respiration data to at least one respiration threshold to identify whether a sudden respiratory event exists; and
suspend a medical procedure of the cardiac navigation and/or visualization system when the respiration assessment logic identifies that the sudden respiratory event exists and during a period of time of the sudden respiratory event, the medical procedure comprising populating the map with electrophysiology data.

15. The respiratory assessment system according to claim 14 , wherein the electrophysiological data comprises impedance data.

16. The respiratory assessment system according to claim 14 , wherein the sudden respiratory event is representative of a current respiratory condition of the patient that is outside of a preset respiration range.

17. The respiratory assessment system according to claim 16 , wherein the preset respiration range is adjustable.

18. The respiratory assessment system of claim 14 , wherein the at least one respiration threshold comprises a peak-to-peak range associated with a first condition.

19. The respiratory assessment system of claim 18 , wherein the at least one respiration threshold further comprises a second peak-to-peak range associated with a second condition different than the first condition.

20. The respiratory assessment system of claim 14 , wherein the at least one respiration threshold comprises a maximum respiration threshold corresponding to patient inhalation and a minimum respiration threshold corresponding to patient exhalation.
