Bryan Patrick Flaherty, Mark Henry Sher, Richard G Caro: Rapid non-invasive blood pressure measuring device. Masimo Corporation, Knobbe Martens Olson & Bear, October 14, 2003: US06632181 (441 worldwide citation)

A blood pressure can be obtained by supplying an external pressure to a portion of an artery. The external pressure is preferably between the systolic and diastolic pressure. An event which occurs at least once a cycle can then be identified. This event can be, for example, a peak in the arterial co ...
