Abstract: A method and apparatus for reducing the workload of titrating drug to effect while leaving clinician users in control of a related procedure is described. A drug delivery device is controlled to achieve a target drug concentration at a selected site in the patient or a predetermined infusion rate waveform. The time profile of the target drug concentration or a predetermined infusion rate waveform is controlled by a drug state model that uses clinical heuristics to implement safe, pre-defined changes in the target drug concentration or infusion rate and user-commanded changes in target drug concentration or infusion rate. The invention allows time to assess the response of the patient to changes in drug level by making small incremental and conservative changes in drug level over time.

Abstract: Disclosed is an apparatus and method for the delivery of inspired gas, e.g., supplemental O2, to a person combined with gas sampling, including for the purpose of monitoring of the ventilation of the person. In the invention, the delivery of inspired gas and gas sampling are accomplished without the use of a sealed face mask. The apparatus of one embodiment of the present invention comprises an oxygen delivery device, nasal airway pressure sampling devices, optionally an oral airway pressure sampling device and at least one pressure analyzer connected to the sampling devices which determine the phase of the person's respiration cycle and the person's primary airway. The oxygen delivery device is connected to a controller such that it delivers a higher flow of oxygen to the person during the inhalation phase of the person s respiratory cycle. The invention thus increases end tidal oxygen concentrations.

Abstract: The invention of this application relates generally to intravenous (IV) infusion of drugs to patients, and more particularly to aspects of an IV infusion system comprising an infusate cassette and an infusate container.

Abstract: The present invention includes systems and methods for decreasing the pain and discomfort commonly associated with endoscopic procedures, where such procedures may be performed with lower dosage levels of sedative and analgesic drugs. The invention includes use of an anesthetic collar coupled to an endoscope with a flexible shaft. The anesthetic collar allows lubricants, local anesthetics, dyes, and/or other desirable fluids to be passed through the existing lumen of the flexible shaft into an annulus, where the fluid may be distributed through expulsion pores into the gastrointestinal tract.

Abstract: The present invention includes a respiratory monitor that improves patient safety through the use of highly responsive monitors and displays highly visible to all clinical personnel even in the absence or failure of an alarm display. The display can be positioned so that clinicians do not have to look away from the patient to view the output of the respiratory monitor. The respiratory monitoring system alerts clinicians of potential problems while automatically taking steps to gather additional information and place an integrated drug delivery system in a safe state (e.g., step down or deactivation) in addition to providing a real-time visual indicator of respiratory rate and estimated tidal volume or respiratory effort and effect. Multiple thresholds that trigger corresponding indicators such as color-coded LEDs provide a quantized display of respiratory effort and effect while also providing a certain level of redundancy. The respiratory effort and effect can also be displayed by the intensity of the LEDs.

Abstract: The present invention provides a sedation and analgesia system having a bite block configured for integration and use with the system. The bite block facilitates access to the mouth while allowing the monitoring and delivery of gas via the oral and/or the nasal cavity where the monitoring and delivery are integrated with a sedation and analgesia system.

Abstract: The present invention includes a sedation and analgesia system having a high sensitivity and specificity for diagnostic and therapeutic algorithms, where the high sensitivity and specificity may be gained by providing multiple monitors for a single patient parameter. The invention also comprises multiple monitors for a single patient parameter, where the monitored data from each monitor is compared with that of the others by a controller in order to ascertain whether monitored data is reliable.

Abstract: The present invention comprises systems and methods for handling large amounts of data prone to ambiguity and artifact in real-time in order to ensure patient safety while performing a procedure involving a sedation and analgesia system. The invention utilizes neural networks to weight data which may be more accurate or more indicative of true patient condition such that the patient condition reported to the controller and the user of a sedation and analgesia system will have increased accuracy and the incidence of false positive alarms will be reduced.

Abstract: The present invention comprises a system that incorporates the natural relationships of patient parameters into a medical monitoring system in order to increase monitoring specificity by reducing false positive alarms resulting from spurious data and inconclusive data. The invention also comprises a system that incorporates the natural relationships of patient parameters in order to use the data obtained from those parameters to non-invasively monitor a patient parameter that typically precludes direct monitoring.
