    Abstract: A decision-support system and computer implemented method automatically measures the midline shift in a patient's brain using Computed Tomography (CT) images. The decision-support system and computer implemented method applies machine learning methods to features extracted from multiple sources, including midline shift, blood amount, texture pattern and other injury data, to provide a physician an estimate of intracranial pressure (ICP) levels. A hierarchical segmentation method, based on Gaussian Mixture Model (GMM), is used. In this approach, first an Magnetic Resonance Image (MRI) ventricle template, as prior knowledge, is used to estimate the region for each ventricle. Then, by matching the ventricle shape in CT images to the MRI ventricle template set, the corresponding MRI slice is selected. From the shape matching result, the feature points for midline estimation in CT slices, such as the center edge points of the lateral ventricles, are detected. The amount of shift, along with other information such as brain tissue texture features, volume of blood accumulated in the brain, patient demographics, injury information, and features extracted from physiological signals, are used to train a machine learning method to predict a variety of important clinical factors, such as intracranial pressure (ICP), likelihood of success a particular treatment, and the need and/or dosage of particular drugs.

    Abstract: Bleeding from blood vessels located in difficult-to-compress regions of the body (especially the abdomen, pelvic or groin region) is controlled by the use of a portable, small-footprint belt-like device that contains multiple inflatable bladders. The inflatable bladders are selectively positioned and inflated over exsanguinating blood vessels, thereby exerting pressure to stop the bleeding. The device may also be used to provide perfusion support in low flow disease states such as hemorrhagic shock and cardiac arrest.

    Abstract: In an emergency medicine patient, accurate measurement of change or lack thereof from non-shock, non-ischemic, non-inflammation, non-tissue injury, non-immune dysfunction conditions is important and is provided, as practical, real-time approaches for accurately characterizing a patient's condition, using Raman (3) and/or fluorescence (30) spectroscopy with a high degree of accuracy. Measurement times are on the order of seconds. High-accuracy measurement is achieved with Raman spectroscopy interrogation of tissue. Simultaneous interrogation by NADH fluorescence spectroscopy may he used. Measurements may be non-invasive to minimally invasive. Preclinical (ultra-early) states of shock can be detected (5), severity can be determined, effectiveness of various treatments can be determined.

    Abstract: A non-invasive method and apparatus for at least partially occluding the descending aorta of a patient and for manipulating core and cerebral temperature includes positioning an elongated tubular member which may have a moveable surface through the esophagus and displacing the moveable surface thereby applying a force posteriorly in the direction of the patient's descending aorta sufficient to partially or substantially completely occlude the descending aorta. The tubular member may include a heat exchange surface and a heat transfer mechanism for transferring heat to the heat transfer surface or for transferring heat from the heat transfer surface in order to modify the temperature of a portion of the patient.

    Abstract: Methods which increase the bioavailability of beneficial gases in the circulatory system are provided. The methods involve administering agents that changes the binding affinity of a medicinal gas such as NO, CO, H2S, N2O, SO, SO2 and O2 for Hb and/or hemoglobin based oxygen carriers (HBOCs). The change results in increased release of gases carried by Hb and HBOCs. As a result, the concentration of the OH gases in circulation is raised, and they are more available to exert their beneficial effects, e.g. in the treatment of disease or conditions caused by low levels of the gases. The methods are optionally used together with administration of medicinal gases and/or administration of HBOCs and/or other non-HBOC gas carriers such as PFC, and as (or in conjunction with) diagnostic methods.
