To describe the principles and the first clinical application of a novel prototype automated weaning system called Evita Weaning System (EWS). EWS allows an automated control of all ventilator settings in pressure controlled and pressure support mode with the aim of decreasing the respiratory load of mechanical ventilation. Respiratory load takes inspired fraction of oxygen, positive end-expiratory pressure, pressure amplitude and spontaneous breathing activity into account.

As a young ensign in the US Navy on a nuclear submarine, Doug Bonacum had to brief the captain of the ship following his night-time shift, reporting about potentially dangerous situations that might emerge. He described the "situation, background, assessment, and recommendation". This nascent SBAR communication tool served temporarily to flatten the hierarchy between the ensign and the ship's captain.

Introduction: Training emergency personnel on the clinical management of a mass-casualty incident (MCI) with prior chemical, biological, radioactive, nuclear, or explosives (CBRNE) -exposed patients is a component of hospital preparedness procedures.

Objective: The objective of this research was to determine whether a Virtual Emergency Department (VED), designed after the Stanford University Medical Center's Emergency Department (ED) and populated with 10 virtual patient victims who suffered from a dirty bomb blast (radiological) and 10 who suffered from exposure to a nerve toxin (chemical), is an effective clinical environment for training ED physicians and nurses for such MCIs.

Methods: Ten physicians with an average of four years of post-training experience, and 12 nurses with an average of 9.

The virtual reality coronary angiography simulator "CATHI" (Catheter Instruction System, Mannheim, Germany) simulates coronary arteries with implemented vessel lesions in virtual patients. Like similar systems the software model runs on common PC systems, which are linked to the mechanical device for manual training. We combined the advantages of this skill trainer with the near to reality assembly of a cardiac catheterization laboratory (Cath-lab) by connecting it to a full scale simulator (HPS, METI, Sarasota, FL).

Background: Training interdisciplinary trauma teams to work effectively together using simulation technology has led to a reduction in medical errors in emergency department, operating room, and delivery room contexts. High-fidelity patient simulators (PSs)-the predominant method for training healthcare teams-are expensive to develop and implement and require that trainees be present in the same place at the same time. In contrast, online computer-based simulators are more cost effective and allow simultaneous participation by students in different locations and time zones.

Background: Application of a LapSim-training model in the Students' Skills Lab as well as the objective evaluation of stress in a virtual operating room scenario offer new perspectives in laparoscopic simulation.

Methods: In a Students' Skills Lab , assessment of learning curves of laparoscopic basic skills and complex tasks was carried out with 28 individuals at a LapSim Virtual Reality (VR)-simulator in a training curriculum consisting of 9 units. In addition, in a virtual operating room scenario, stress evaluation was performed with 18 surgeons by means of a sympathicograph and, in that way, the laparoscopic error and complication rate were recorded.

Training of medical personnel using simulation techniques is an acknowledged measure of process optimization and quality assurance in a clinical setting. In 2006, a simulator-based training of anaesthesiologists was introduced in the University Medical Centre of Schleswig-Holstein, Campus Kiel, Germany. The training was performed on a human patient simulator (Meti, Sarasota, USA) and the course was conducted by instructors and engineers from the Simulation Centre Mainz in an operation room equipped with common anaesthesia devices.

Trauma from 'Dirty' Bomb blasts presents complex clinical problems to healthcare providers who must make critical emergency care decisions with incomplete information, usually limited initially only to cursory observations and vital signs. A set of simple, HFSM patho-physiological models of hypovolemic shock based upon blood volume deficits and remedial therapeutic actions has been created for 10 Virtual World scenarios used for training healthcare personnel in the diagnosis and management of 'dirty' bomb victims. Several general rules define the models: * Virtual patients have individual characteristics of gender, age, health status.

Background: Minimally invasive surgery causes higher mental strain for surgeons than conventional surgery and is significantly more stressful in consecutive cases. This study aimed to investigate whether individual stress responses are associated with intraoperative alterations of manual surgical skills and technical errors of the laparoscopic surgeon.

Methods: The LapSim virtual reality simulator was used.

Objective: In our effort to establish criterion-based skills training for surgeons, we assessed the performance of 17 experienced laparoscopic surgeons on basic technical surgical skills recorded electronically in 26 modules selected in 5 commercially available, computer-based simulators.

Methods: Performance data were derived from selected surgeons randomly assigned to simulator stations, and practicing repetitively during one and one-half day sessions on 5 different simulators. We measured surgeon proficiency defined as efficient, error-free performance and developed proficiency score formulas for each module.

An important component of all emergency medicine residency programs is managing trauma effectively as a member of an emergency medicine team, but practice on live patients is often impractical and mannequin-based simulators are expensive and require all trainees to be physically present at the same location. This article describes a project to develop and evaluate a computer-based simulator (the Virtual Emergency Department) for distance training in teamwork and leadership in trauma management. The virtual environment provides repeated practice opportunities with life-threatening trauma cases in a safe and reproducible setting.

In a mass casualty incident, injured and at-risk patients will pass through a continuum of care from many different providers acting as a team in a clinical environment. As presented at MMVR 14 [Kaufman, et al 2006], formative evaluations have shown that simulation practice is nearly as good as, and in some cases better than, live exercises for stimulating learners to integrate their procedural knowledge in new circumstances through experiential practice. However, to date, multiplayer game technologies have given limited physiological fidelity to their characters, thus limiting the realism and complexity of the scenarios that can be practiced by medical professionals.
