A system for measuring blood circulation parameters in a patient, comprising: a) a pressing element; b) a contact microphone which is acoustically coupled to the patients body by the pressing element at a location adjacent to an artery, the microphone thereby producing a data signal indicative of blood circulation in the artery; and c) a controller which integrates in time the data signal from the microphone, thereby determining a blood pressure as a function of time, at least up to an unknown integration constant. |
