AUTOMATED FLUID INFUSION CONTROL FOR CIRCULATORY SUPPORT AND ECMO SYSTEMS

The present disclosure provides systems for controlling infusion of one or more supplements into blood received from a patient. The systems may include at least one extracorporeal circulatory support system including a pump, fluid conduits, and at least one sensor configured to measure one or more parameters of the blood. The system also may include a fluid flow regulator coupled to the extracorporeal circulatory support system; and a processor, a memory, and associated circuitry communicatively coupled to the at least one sensor and the at least one fluid flow regulator. The system receives measurement signals corresponding to parameters of blood from the at least one sensor and determines one or more target values for the parameters of blood based on a patient profile and/or the measurements. The system may control the fluid flow regulator to cause an infusion of at least one supplemental fluid from a supplemental fluid source into the blood.

System and a corresponding method for estimating respiratory drive of mechanically ventilated patients

The present invention relates to a system (10) and a corresponding method for estimating the respiratory drive (R_DRIVE) of mechanically ventilated patients, and for preferably apportioning this respiratory drive into one, or more, components related to the chemical drive—i.e. the drive due to the chemoreceptor response—and/or the muscular drive—i.e. the contraction of respiratory muscles, for example the diaphragm. The principle of the invention is that respiratory drive can be obtained from measuring the patient's response to small changes in mechanical ventilation settings (Vt_SET), and that this can be apportioned into chemical and/or muscular effects depending upon the changes in respiratory frequency, and/or arterial or end tidal CO.sub.2 levels, and/or arterial blood p H.

Medicine delivery and animal management systems

Embodiments disclosed herein include devices for time release of measured quantities of an active ingredient and storage of animal management information. One embodiment disclosed herein releases an active ingredient, and then, at optionally varied intervals, releases additional doses into the same environment. The active ingredients are compartmentalized and, upon receiving an appropriate signal, open to dispense the active ingredient into the animal. Accordingly, in one embodiment, a device includes an engagement member to move a cap to dispense the active ingredient, and in another embodiment, includes a pellet that is attached to the cap to move the cap and dispense the active ingredient.

Adaptive system for blood fluid removal

Methods for monitoring patient parameters and blood fluid removal system parameters include identifying those system parameters that result in improved patient parameters or in worsened patient parameters. By comparing the patient's past responses to system parameters or changes in system parameters, a blood fluid removal system may be able to avoid future use of parameters that may harm the patient and may be able to learn which parameters are likely to be most effective in treating the patient in a blood fluid removal session.

Medical monitoring hub

The present disclosure includes a medical monitoring hub as the center of monitoring for a monitored patient. The hub includes configurable medical ports and serial ports for communicating with other medical devices in the patient's proximity. Moreover, the hub communicates with a portable patient monitor. The monitor, when docked with the hub provides display graphics different from when undocked, the display graphics including anatomical information. The hub assembles the often vast amount of electronic medical data, associates it with the monitored patient, and in some embodiments, communicates the data to the patient's medical records.

A method for determining and responding in real-time to an increased risk of death relating to a patient with epilepsy is provided. The method includes receiving cardiac data and determining a cardiac index based upon the cardiac data. The method includes determining an increased risk of death associated with epilepsy if the indices are extreme, issuing a warning of the increased risk of death and logging information related to the increased risk of death. Also presented is a second method for determining and responding in real-time to an increased risk of death relating to a patient with epilepsy comprising receiving at least one of arousal data, responsiveness data or awareness data and determining an arousal index, a responsiveness index or an awareness index, where the indices are based on arousal data, responsiveness data or awareness data respectively. The second method includes determining an increased risk of death related to epilepsy if indices are extreme values, issuing a warning of the increased risk of death and logging information related to the increased risk of death. A computer readable program storage device is also provided. Also provided is a method for receiving body data, determining a cardiac, an arousal, a responsiveness, or a kinetic index, determining an increased or increasing risk of death over a first time window relating to a patient with epilepsy and issuing a warning and logging relevant information.

LIQUID VENTILATOR AND METHOD TO INDUCE TIDAL LIQUID VENTILATION AND/OR HYPORTHERMIA

Liquid ventilator and methods integrating the concept of total liquid ventilation (TLV) using liquid volumes below functional residual capacity (FRC) of mammal's lungs are disclosed. Beyond the automatization of the whole process, the technology has been up-scaled to confirm that TLV at residual volumes below FRC can provide a safe procedure while enabling the full potential of TLV in a mammal such as humans or adult-sized animals. Such tidal liquid ventilation strongly differs from the previously known TLV approach, opening promising perspectives for a safer clinical translation. Also disclosed are apparatus and method for safe and fast induction of hypothermia during liquid ventilation of a mammal.
