DETERMINING A CHARACTERISTIC BLOOD PRESSURE
First Claim
1. A method for determining a characteristic physiological parameter of a patient, the method comprising:
- determining a physiological parameter of the patient based at least in part on a signal obtained from a patient sensor;
detecting a first physiological parameter event, wherein the first physiological parameter event is detected based at least in part on a first altered portion of the physiological parameter; and
determining the characteristic physiological parameter of the patient based at least in part on a selected portion of the physiological parameter other than the first altered portion of the physiological parameter, wherein the characteristic physiological parameter is determined to assess a clinical status of the patient.

Abstract
The present disclosure relates to monitoring a characteristic physiological parameter of a patient during a suitable time period that either precedes or follows a triggering event, such as a clinician/patient interaction, that may negatively impact the physiological parameter. In some embodiments, physiological parameter values falling between one or more pre-set thresholds may be used to derive the characteristic physiological parameter. In some embodiments, tracking the physiological parameter may provide additional information about the patient'"'"'s status. In some embodiments, confidence measures may be associated with, or may be used to analyze features of the patient signal to derive information about, the characteristic physiological parameter. The patient signal used to derive a patient'"'"'s physiological parameter may be of an oscillatory nature or may include oscillatory features that may be analyzed to derive a characteristic respiration rate.
