Abstract
A method and system for improving or optimizing the collection of data from and the delivery of therapy to a patient by an implantable medical device (IMD) is disclosed which uses information about the patient's respiratory cycle.
Claims26
A computer-readable medium programmed with instructions for performing a method of collecting hemodynamic data in an implantable medical device, the medium comprising instructions for causing a programmable processor to:
- monitor respiratory cycles of a patient, including determining when an inspiration phase is occurring and when an expiration phase is occurring;
- identify at least one timing reference point of a respiratory cycle;
- collect a set of hemodynamic data from the patient at intervals based on the at least one timing reference point of a respiratory cycle such that all data in the set were obtained during approximately the same portion of the respiratory cycle;
- and
- collect multiple sets of hemodynamic data using multiple timing reference points.
