Methods for monitoring central-to-peripheral arterial pressure decoupling, i.e., hyperdynamic or vasodilation conditions are described. These methods involve the comparison of parameters such as impedance, compliance, and pressure that can be determined from flow and pressure measurements at central aortic and peripheral arterial locations. The relationship between the parameters at the central aortic and peripheral arterial locations provides an indication of central-to-peripheral arterial pressure decoupling. These methods can be alert a user that a subject is experiencing central-to-peripheral arterial pressure decoupling, which can enable a clinician to appropriately provide treatment to the subject.
