HYDROSTATIC OFFSET ADJUSTMENT FOR MEASURED CARDIOVASCULAR PRESSURE VALUES

摘要

In some examples, a method for monitoring a cardiovascular pressure in a patient includes storing, in a memory of an implantable medical device system and in association with each one or more different patient postures, a respective offset value for the cardiovascular pressure of the patient. The one or more offset values may be determined based on one or more of a distance between an implantable pressure sensing device and an anatomical structure of the patient, a location of the implantable pressure sensing device within the patient, or one or more dimensions an anatomical structure of the patient. The method further includes determining a measured value of the cardiovascular pressure and a posture of the patient when the value of the cardiovascular pressure was measured, selecting one of the stored offset values associated with the current patient posture, and determining an adjusted cardiovascular pressure value.
