An immersive virtual reality emergency medicine training simulator for military medical personnel.
This simulator uses the Unity game engine and Pulse to provide dynamic physiological feedback
on the patient's condition from a wide range of injuries and treatments.
Medical Simulation and Training Architecture (MSTA)
The MSTA platform provides an open standard to connect manikins, part-tasks trainers, physiology engines, and other simulation technologies to support the creation of complex training systems necessary for future force readiness efforts.
MSTA successfully demonstrated an integrated TCCC training scenario that took a wounded virtual patient from field care to role 2 care. The training system consisted of a manikin, a custom control panel, a part task trainer, the Pulse physiology engine and an after action review engine.
This work was performed under Contract #W900KK-17-C-0041
Ventilation Management Trainer
A training simulator designed to mimic respiratory distress during mechanical ventilation. A simulated torso was developed and integrated with a Special Medical Emergency Evacuation Device. It is affixed with medical equipment utilized during Critical Care Air Transport Team missions. The torso includes a lung model, upper airway, and head with reproducible computerized algorithms. The simulator is responsive to treatment of conditions encountered during mechanical ventilation.
Pulse is fully integrated to autonomously drive all patient responses..
An interactive, multiplayer 3D healthcare and medicine themed, STEM education product. BioMojo VPE is designed to inspire and educate youth towards careers in healthcare, clinical research and biomedical engineering through fun, challenging virtual role play, teamwork, and problem-solving. Themes include emergency medicine, preventable chronic diseases, physiology, anatomy, genomics, and pharmacotherapy.
Players will perform (virtual) diagnostic procedures and other interactions with virtual patient avatars. Virtual patient physiology is provided by Pulse.
A system for investigating closed-loop physiology management for critical care with in-silico patients. Closed-Loop Assistants (CLAs) are designed to leverage medical device interfaces to add computers/algorithms to the clinical care loop to aid indecision-making and to implement the automatic application of interventions.
Combat Casualty Care Augmented Reality Intelligent Training System (C3ARESYS)
An augmented reality system to improve the realism of Combat Medics (68W) and Combat Lifesavers scenario-based training. C3ARESYS provides the opportunity to train on wounds and casualties that respond to treatments with feedback adapted to the trainee's skill level. C3ARESYS offloads work from the instructor, enabling focus on teaching rather than fixing shortcomings in casualty simulation.
Pulse is used to provide dynamic interactions to the patient and provide physiological feedback from the patient.
A CPR simulator with real-time compression feedback and features to monitor performance metrics, such as time-to-CPR, compression depth, and rate. This system is controlled by a microcontroller to count the number of chest compressions and ghe pressure applied. The data is passed to the Pulse physiology engine in real-time and the state of the patient changes dynamically based on sensor inputs.
Extra Corporeal Membrane Oxygenation (ECMO) Training Simulator
A full-fledged training simulator of various procedures and scenarios involved in ECMO and the associated complications. The simulator has three main parts:
A physical cardiovascular circuit that mimics the human circulation system, including an artificial human heart and a synthetic vasculature with cannulation pads.
A physical ECMO circuit to simulate oxygenation with a color changing blood simulant, an external pump to regulate flow, and sensors to monitor vitals.
A mathematical model of human physiology simulating respiratory failure and cardiac arrest based on Pulse Physiology Engine. Pulse helps to simulate clinical scenarios (i.e., hypovolemia, hypoxia, etc.) by controlling the cardiovascular and ECMO circuits, and provides real-time physiological feedback for experimental training.
Simulating three valvular conditions: aortic stenosis, aortic regurgitation, and mitral stenosis. Pulse virtual physiology software has the potential to transform medical education by allowing medical students to learn in a consequence-free environment. Medically accurate physiology models are required to ensure that lessons learned virtually translate to the real world.
A high-fidelity computational surrogate head model focused on the ventricular system to optimize the performance of ventriculoperitoneal shunts. The cerebrospinal fluid model is being coupled with the cerebrovascular system using the Pulse physiology engine. In addition to globally quantifying the essential cerebrovascular parameters for the local high-fidelity analysis of shunt function, Pulse also provides an invaluable training capability to teach students about the effects of elevated ICP due to hydro-cephalus on the entire body.
A surgical planning tool for subglottic stenosis that incorporates three major components.
VPAW initiates with a CT scan of the patient and obtains a geometrical model through segmentation and surface reconstruction.
It then employs a computational fluid dynamics (CFD) engine based on a Lattice-Boltzmann formulation to provide airflow parameters for Pulse. Pulse then provides the physiologic response due to the airflow.
A real-time geometric authoring tool allows surgeons to edit the tracheal geometry using a haptic device as part of a surgical planning. VPAW calculates the physiologic results of each plan to be assessed by surgeons to identify the best course of action.
