  • Publication number: 20150265218
    Abstract: Improved methods and apparatus for non-invasively assessing one or more parameters associated with fluidic systems such as the circulatory system of a living organism, when such parameters are potentially affected by other concurrent events. In one exemplary embodiment, apparatus and methods for compensating for occlusive events (e.g., pressure cuff inflation) occurring ipsilateral to the location of parameter measurement are disclosed. Upon passive detection of signal degradation resulting from the event, the apparatus selectively enters a “wait state” wherein further processing of the hemodynamic data is suspended until the degrading event subsides. This behavior mitigates any adverse effects the event might have on the accuracy of the representation of the measured hemodynamic parameter generated by the system. In another exemplary embodiment, the measured data is analyzed in order to classify the type of event (e.g.

  • Publication number: 20070287925
    Abstract: Improved apparatus and methods for non-invasively assessing one or more parameters associated with systems such as fluidic circulating systems (e.g., the circulatory system of a living organism). In a first aspect, an improved method of continuously measuring pressure from a compressible vessel is disclosed, wherein a substantially optimal level of compression for the vessel is achieved and maintained using dynamically applied dither perturbations (e.g., modulation) on the various axes associated with the vessel. In a second aspect, an improved apparatus and method are provided for monitoring hemodynamic parameters, such as blood pressure, in a continuous and non-invasive manner while operating under a single unifying scheme. One variant of this scheme using a simulated annealing (SA) type approach to determining and maintaining an optimal operating state.
