1. A method for calibrating a blood pressure monitor, the method comprising:
- receiving a photoplethysmograph (PPG) signal;
monitoring a value of at least one metric derived at least in part from the PPG signal;
comparing the value of the metric to a stored value;
determining based at least in part on the comparison whether the value of the metric corresponds to the stored value; and
determining whether to update current calibration parameters of the blood pressure monitor based at least in part on the comparison.

Abstract
Systems and methods are provided for storing and recalling metrics associated with physiological signals. It may be determined that the value of a monitored physiological metric corresponds to a stored value. In such cases, a patient monitor may determine that a calibration is not desired. In some cases, a patient monitor may recall calibration parameters associated with the stored value if it determined that the stored value corresponds to the monitored metric value.

11. A system for determining physiological information about a subject, the system comprising:
-
a signal input configured to receive at least one PPG signal of a subject from at least one sensing device; at least one processing device coupled to the signal input, wherein the at least one processing device is configured to; monitor a value of at least one metric derived at least in part from the at least one PPG signal; compare the value of the at least one metric to a stored value; determine based at least in part on the comparison whether the value of the metric corresponds to the stored value; and determine whether to update calibration parameters of the blood pressure monitor based at least in part on the comparison. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
