First Claim
Patent Images
1. A method comprising:
- receiving, by a processor in a medical device system, a measured impedance value of a urinary bladder of a patient;
receiving, by the processor, a determined posture of the patient; and
determining, with the processor, a filling status of the urinary bladder of the patient based on the measured impedance value of the bladder of the patient and the determined posture of the patient, wherein the measured impedance value is associated with a plurality of filling statuses, the plurality of filling statuses including the determined filling status.
