Technology should not be the limiting factor to the educational simulation experience. Mannequins in medical simulation offer a broad array of capabilities: anatomical realism, physiological responsiveness to drugs, audible cardio-pulmonary-gastrointestinal systems, palpable circulatory pulses, technical-controlled verbal responses, and wave-form production and display. Specialized mannequins range from neonate and children to gravid patients. Task-trainers provide simulation for directed skills such as intubation models for airway management, pelvic models for gynecologic exams, and upper thoracic models for central line placement. Finally, virtual reality and hybrid virtual reality offer promise for simulation where physical models are not available, more notably non-invasive surgery. Another aspect of the technology behind simulation is the audiovisual monitoring and recording available to monitor and record the simulation for later viewing.
