UK-based photographer Jim Johnston balances his commercial and editorial work with personal projects that creatively explore technology and geography. Medical Simulation is his recent work shot at The Bristol Medical Simulation Centre, a training facility in West England that provides medical students and clinicians the opportunity to rehearse and perfect procedures on Human Patient Simulators (HPS’s)—fullscale and fully interactive human body simulators—in efforts to improve competency and reduce the 1-5% of accidental hospital deaths that occur due to human error. HPS’s are highly sophisticated and programmed to respond to drugs and simulate life-threatening emergencies—they also make for quite an interesting photographic project.
