Publication number: 20060224059Abstract: Embodiments of the present invention relate to a sensor for facilitating detection of a physiological characteristic of a patient. Specifically, one embodiment includes a detector configured to obtain signals from the patient, the signals being indicative of the physiological characteristic and to send the signals to a monitor, and a sensor memory coupled with the sensor and separate from the monitor, the sensor memory storing patient physiological data derived by the monitor from the signals, the patient physiological data being indicative of the physiological characteristic.Type: ApplicationFiled: June 1, 2006Publication date: October 5, 2006Applicant: Nellcor Puritan Bennett Inc.Inventors: David Swedlow, Stephen Daleo, Thomas Yorkey, Edward Richards, Charles Porges, Charles Stuart, Daniel Nemits, Russell DeLonzor

Publication number: 20060183988Abstract: A method and apparatus for reducing the effects of noise on a system for measuring physiological parameters, such as, for example, a pulse oximeter. The method and apparatus of the invention take into account the physical limitations on various physiological parameters being monitored when weighting and averaging a series of measurements. Varying weights are assigned different measurements, measurements are rejected, and the averaging period is adjusted according to the reliability of the measurements. Similarly, calculated values derived from analyzing the measurements are also assigned varying weights and averaged over adjustable periods. More specifically, a general class of filters such as, for example, Kalman filters, is employed in processing the measurements and calculated values. The filters use mathematical models which describe how the physiological parameters change in time, and how these parameters relate to measurement in a noisy environment.Type: ApplicationFiled: April 18, 2006Publication date: August 17, 2006Inventors: Clark Baker, Thomas Yorkey

Publication number: 20060030764Abstract: Sensors and monitors for a physiological monitoring system having capability to indicate an accuracy of an estimated physiological condition. The sensor senses at least one physiological characteristic of a patient and is connectable to a monitor that estimates the physiological condition from signals detected by the sensor. The sensor includes a detector for detecting the signals from the patient which are indicative of the physiological characteristic. The sensor is associated with a memory configured to store data that defines at least one sensor signal specification boundary for the detected signals. The boundary is indicative of a quality of the signals and an accuracy of the physiological characteristic estimated from the signals by the monitor. The sensor further includes means for providing access to the memory to allow transmission of the data that defines the at least one sensor boundary to the monitor.Type: ApplicationFiled: September 30, 2005Publication date: February 9, 2006Applicant: Mallinckrodt Inc.Inventors: Charles Porges, Clark Baker, Thomas Yorkey, Michael Bernstein, Paul Mannheimer
