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.

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.

A disposable, closed fluid sampling system for use with a medical conduit line, especially for taking blood samples from a pressure monitoring line. The conduit line has at least one fluid sampling site interposed between a distal segment of tubing and a proximal segment of tubing. The system includes a disposable subsystem having a bypass cannula adapted to engage the sampling site, a reservoir for drawing a prime volume of fluid past the sampling site, and a fluid sampling container. A 3-way stopcock may connect the reservoir, bypass cannula, and sampling vessel for controlling the sampling procedure. The bypass cannula may simultaneously place the subsystem into fluid communication with an inner chamber of the sampling site and exclude the proximal segment of the conduit line. Alternatively, a stopcock immediately adjacent the sampling site in the proximal segment may be utilized. A method of using the system includes attaching the disposable subsystem, opening the reservoir to the distal segment while excluding the proximal segment, drawing a prime volume of fluid into the reservoir, opening the sampling vessel to the distal segment and drawing a sample, re-infusing the prime volume into the distal segment, and removing and discarding the subsystem. The reservoir remains attached between the prime volume draw and re-infusion and is thus “closed.”

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.

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.

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. 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.

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.

Disclosed herein are devices, systems, and methods that automate the identification of the start and end of a fluid bolus and calculate the volume of fluid given during the challenge. A flow measurement device is used to measure fluid flow in a conduit (e.g., IV tubing) and an algorithm is used to determine a start time and the stop time of a fluid bolus. In addition, the volume of fluid given during the bolus is calculated. Advantageously, this provides accurate and automatic collection of the start time of the fluid bolus, the income of the fluid bolus, and the volume of the fluid bolus. Historically, these data are estimated by the clinician used to assess the hemodynamic response to the fluid bolus.
