Abstract
An apparatus, operation and method for measurement of systemic and/or pulmonic blood pressure. The present invention offers a passive non-invasive method and system that can be used where measurement of systemic pressure with a traditional blood pressure cuff is contraindicated. The present invention also affords a means for early diagnosis and opportunity for intervention in patients with no symptoms or signs of elevated pulmonary blood pressure that can be performed as part of a routine physical exam. The present invention accomplishes this non-invasive measurement through detection, identification and characterization of the second heart sound acoustic signature associated with heart valve closure. An apparatus for measuring systemic and/or pulmonic blood pressure in accordance with the present invention includes a sensor assembly comprising a housing, an electronic module, a shock dampener, a mounting means, a transducer, an acoustic coupling and a back cover. The sensor assembly is connected to a data acquisition module which in turn is connected to a signal processing means, a remote connection means and a monitor. An improved acoustic coupling is disclosed that provides low-…
