Delays in the detection of OH are associated with a "failure to rescue" and a dramatic deterioration in prognosis once the onset of clinically frank shock has occurred. An early alert to the presence of OH with an acceptable rate of false-positives and false-negatives would save countless lives. Additionally, such technology would save significant time, money and effort by allowing medical resources to be applied more accurately - the essence of precision medicine. An automated system would monitor currently stable patients continuously, leaving clinicians free to care for patients in need of attention.', 'detailedDescription': 'The investigators will enroll 480 trauma patients in a "no significant risk" prospective clinical trial to 1) evaluate the performance of a Mark I prototype, 2) validate the performance of the Phase II algorithm, and 3) re-train the algorithm to Phase III iteration.\n\nThis is not a therapeutic study. The main outcome variables are non-invasive measurements that will be used for machine learning, not real-time patient management. The data generated will be used later for discovery and validation in traditional and innovative machine learning.\n\nAs a minimal risk study, there will be no change from standard of care for patients undergoing surgery. The surgical procedures and pharmacotherapies will proceed as per standard clinical management.\n\nEnrolled patients will undergo standard preoperative, anesthetic, and postoperative physiological monitoring that includes:\n\nElectrocardiogram: Heart rate and electrical activity of the heart will be recorded via a 3-lead ECG.\n\nArterial Oxygen Saturation (SpO2): Pulse oximetry will be recorded using a commercially available finger pulse oximeter.\n\nFinger Photoplethysmography: waveforms will be obtained non-invasively from either the SpO2 photoplethysmography or alternatively a Flashback Technologies Compensatory Reserve Index (CRI™) device.\n\nIn addition to these standard physiologic measurements, as a part of the research, the investigators will also acquire the following non-invasive optical and impedance measurements. All of these devices have been previously validated as non-invasive and safe in humans. The impedance electrodes and optical emitter/detectors will be incorporated into easily applied latex-free based "belts" that will be applied to anatomic locations along the thorax, abdomen and thigh. Application of these belts will be as soon as practical after patient arrival.\n\nThe clinicians providing care to the patient will be blind with respect to the measurements from these devices.\n\nContinuous-wave Near-Infrared Spectroscopy (CW-NIRS) Device, custom built:\n\nThe device is built on an Ocean Optics FLAME USB Spectrometers, with two OSRAM 4736 NIR LEDs in plastic holders meant to be taped or strapped to the patient on the chest/torso and thigh locations. An Oceans Optics tungsten-halogen light source is used for an additional probe location on the forehead. Probe holders are designed to collect light from surface of skin by means of a mirror and collimator. The device will collect data on light attenuation of muscle in models of shock/trauma. The light output for all locations is below the ANSI limits for maximum permissible skin exposure.\n\nSwissTom Electrical Impedance Tomography (EIT) System:\n\nName of device: Pioneer Set (Electrical Impedance Tomography System) Device Manufacturer: SwissTom AG (Parent company SenTec AG)\n\nThis device monitors dynamically changing perfusion physiology. To record multiplexed impedance signature a belt of 16-32 electrodes is placed around the thorax above the nipple line and thigh and impedances are recorded between multiple sets of electrodes.\n\nSwissTom develops a clinical EIT system that is approved for pulmonary imaging. This Pioneer system is their research platform that has similar functionality and safety performance to their clinical system but provides research teams with access to raw data and additional functionality for specifying imaging parameters (e.g. control of frame rates, signal frequency acquisition, electrode drive patterns).\n\nScioSpec MultiChannel Electrical Impedance Spectroscopy (EIS) System:\n\nName of device: ISX-Mini (MultiChannel Electrical Impedance Spectroscopy System) Device Manufacturer: ScioSpec\n\nTo record multiplexed impedance signatures- an array of 4 electrodes is placed around the cranium and thorax of the patient and impedance spectroscopy signatures are recorded at each anatomic location. This device monitors dynamically changing intracranial, intrathoracic and intra-abdominal physiology.\n\nGeneral Approach to Minimize Risk:\n\nThis protocol will be minimal risk to patients as there is little risk associated with the placement of these devices and they can be removed at any time. They don\'t interfere with standard equipment used in clinical management of trauma patients.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
