First Claim
Patent Images
1. A method of calibrating a pressure measurement system at least partially in pressure communication with a site within a medical patient, comprising:
- measuring a first pressure at a first location at least partially within the medical patient;
measuring a second pressure at a second location;
inducing one or more perturbations, wherein said one or more perturbations causes the first pressure to have a calculable relationship with the second pressure;
determining one or more adjustment factors based on said calculable relationship; and
adjusting said pressure measurement system based at least in part on said one or more adjustment factors.
