Abstract

Systems and methods are described for obtaining and acting upon information indicative of circulatory health and related phenomena in human beings or other subjects.

Claims

1. A medical or veterinary monitoring system comprising:

circuitry for obtaining a local symptom of vascular occlusion; and

circuitry for selecting a first notification mode partly based on the local symptom of vascular occlusion and partly based on an additional indication of hemodynamic instability.

2. The medical or veterinary system of claim 1, in which the circuitry for selecting a first notification mode partly based on the local symptom of vascular occlusion and partly based on an additional indication of hemodynamic instability comprises:

circuitry for deciding to use the first notification mode partly based on an apparent failure of a second notification mode.

3. The medical or veterinary system of claim 1, in which the circuitry for selecting a first notification mode partly based on the local symptom of vascular occlusion and partly based on an additional indication of hemodynamic instability comprises:

circuitry for obtaining another local symptom of vascular occlusion as the additional indication of hemodynamic instability.

4. The medical or veterinary system of claim 1, in which the circuitry for selecting a first notification mode partly based on the local symptom of vascular occlusion and partly based on an additional indication of hemodynamic instability comprises:

circuitry for causing a selection of the first notification mode responsive to one or more indications of clot movement.
