摘要： A patient treatment monitoring system includes an interface for receiving multiple different types of patient medical information including data derived from a patient monitoring device and a patient medical imaging device. A data processor processes the received multiple different types of patient medical information to be suitable for presentation in a display image. A display processor initiates generation of data representing a single composite display image including an image element representing multiple sequentially performed individual stages of a treatment process. The individual stages are associated with corresponding different sets of the received multiple different types of patient medical information. The single composite display image includes multiple image areas for displaying one of the corresponding different sets of the received multiple different types of patient medical information, in response to user selection of a particular stage of the individual stages using the image element.

摘要： A system provides an image acquisition trigger signal compensated for signal processing time delay. An interface receives waveform signal data representing electrical activity of a patient heart over at least one heart beat cycle. A detector detects a particular point associated with a particular signal portion within successive heart beat cycles of the signal data. A first time variation detector provides a first timing adjustment signal in response to detected change in time of occurrence of the detected particular point. A second time variation detector provides a second timing adjustment signal in response to comparison of relative timing of the trigger signal and the detected particular point. An output processor generates the trigger signal in response to the detected particular point and the first timing adjustment signal and the second timing adjustment signal.

摘要： A system provides early prediction of heart tissue malfunction and electrophysiological pathology by determining anatomical tissue impedance characteristics for use in medical patient monitoring and treatment decision making. At least one repository of data indicates multiple predetermined expected impedance value ranges for corresponding multiple impedance measurements taken at multiple particular different sites of at least one anatomical organ. An impedance measurement processor automatically determines whether multiple measured impedance values taken at multiple particular different sites of an anatomical organ using an invasive catheter are within corresponding multiple predetermined expected impedance value ranges derived from the at least one repository. An output processor automatically communicates data comprising at least one message to a destination. The at least one message includes data indicating whether the multiple measured impedance values taken at the multiple particular different sites of the anatomical organ are within the corresponding multiple predetermined expected impedance value ranges.

摘要： A system for respiration or cardiac condition characterization and abnormality detection includes an interface that receives data representing a signal indicating concentration of carbon dioxide in patient gases over multiple signal cycles. A signal processor uses the received data in determining multiple amplitude related characteristic values. A comparator compares at least one of the amplitude related characteristic values or a value derived from the amplitude related characteristic values, with a threshold value to provide a comparison indicator. A patient monitor in response to the comparison indicator indicating an amplitude related characteristic value or a value derived from the amplitude related characteristic values, exceeds the threshold value, generates an alert message associated with the threshold.

摘要： An organ perfusion apparatus and method monitor, sustain and/or restore viability of organs and preserve organs for storage and/or transport. Other apparatus include an organ transporter, an organ cassette and an organ diagnostic device. In perfusion, organ perfusion pressure is preferably controlled in response to a sensor disposed in an end of tubing placed in the organ, by a pneumatically pressurized medical fluid reservoir, providing perfusion pressure fine tuning, overpressurization prevention and emergency flow cut-off. In the hypothermic mode, the organ is perfused with a medical fluid, preferably a simple crystalloid solution containing antioxidants, intermittently or in slow continuous flow. The medical fluid may be fed into the organ from an intermediary tank having a low pressure head to avoid organ overpressurization. Viability of the organ may be automatically monitored, preferably by monitoring characteristics of the medical fluid perfusate. The perfusion process can be automatically controlled using a control program.
