Abstract: Various fluid delivery systems are described comprising an infusion pump having a housing with a first opening and a hollow interior portion that is configured to receive a cartridge having a tubing. A pump unit can be disposed within the housing. The pump unit comprises a motor mechanically coupled with a crank shaft or eccentric cam that is configured to move a set of pistons or other objects to thereby compress one or more portions of the tubing over time as the crank shaft or eccentric cam rotates.

Abstract: Systems and methods are described for presenting information for managing a vital sign of a patient. A graphical user interface (GUI) can be presented that displays information concerning a vital sign of a patient, including the most current value of the vital sign received and past values of the vital sign over an elapsed time period. Preferably, the systems and methods are used with a closed-loop system that may automatically adjust a dosage rate of a medication, although manual control is also contemplated. The GUI may comprise one or more visual indicators presented on the historical data that, when selected, present additional information that may be useful to managing the care of the patient.

A graphical user interface (GUI) can be presented that displays information concerning a vital sign of a patient, including the most current value of the vital sign received and past values of the vital sign over an elapsed time period. Using this information, a time in target value can be generated representing an amount of elapsed time the patient's measured vital sign was within a predetermined range. Preferably, the systems and methods are used with a closed-loop system that may automatically adjust a dosage rate of a medication, although manual control is also contemplated. The GUI may comprise one or more visual indicators presented on the historical data that, when selected, present additional information that may be useful to managing the care of the patient.

Abstract: The disclosure generally relates to a patient monitoring and display system. The system allows a clinician to trigger the occurrence of a clinical event, and record a patient's status following the clinical event. The system calculates and displays a change in a patient's status resulting from the clinical event. The system allows multiple parameters to be tracked and displayed on a single screen. The system can also display various animated organs, such as a heart or a lung, corresponding to an operation of the organs in the patient.

Abstract: Methods for monitoring central-to-peripheral arterial pressure decoupling, i.e., hyperdynamic conditions, are described. These methods involve the comparison of parameters calculated from multivariate statistical models established for both subjects experiencing normal hemodynamic conditions and subjects experiencing hyperdynamic conditions, in which central- to peripheral decoupling may occur. The difference or ratio between the parameters calculated using the two multivariate statistical models provides a continual indication of the level of decoupling as well as indicating peripheral decoupling when a threshold value is exceeded. These methods can be used to both alert a user to the fact that a subject is experiencing peripheral decoupling and provide accurate arterial tone measurements, which enable the calculation of accurate values for other parameters, such as stroke volume and cardiac output.

Abstract: In one embodiment the present invention provides a wireless communication system for medical sensor data. This communications system includes a portable unit that connects to a wireless sensor and a monitor unit that connects to a sensor monitor. Once activated, the units will self organize into a wireless communication structure controlled by the portable unit. As other pairs of units activate, they can self-organize their transmissions by joining an existing network or by creating new networks.

Abstract: A calibration system for pressure monitoring including a sensor positioned at a sensor location on or in a patient's body, a first pressure transducer positioned at a reference location remote from the sensor location to receive a signal from the sensor and to generate a first pressure signal, a calibration device positioned along a plane that is substantially coincident with a chamber or cavity (e.g., a heart chamber) of the patient to measure a reference pressure signal that represents a difference in pressure between the position of the calibration device and the reference location, a second pressure transducer positioned at the reference location remote from the sensor location to receive the reference pressure signal from the calibration device and to generate a calibration pressure signal, and an electronic device to produce an actual pressure signal using the first and calibration pressure signals.
