Pupils dilate or constrict depending on the level of light Arm that moves if anaesthesia insufficient Computer simulation and control in an adjacent room, with visual and audio observation. Simulator is set to particular patient parameters, eg age, obesity. Inbuilt equations compute the response to anaesthetics and drugs. Trauma parameters, eg blood loss, are entered by operator. A range of secific events, eg heart attack, can be triggered, and produce a full range of symptoms.
Operator can speak as the patient.
Under table equipment Provides spontaneous action of lungs, absorption of O 2 and addition of CO 2 Generation of blood pressure, including pulse, and ECG signals. Gas analyser that will determine the gas mixture in the mannequin's lungs and transmit that information to the real-time computer for use in the physiological models. Reliance on video display, separation of visual and haptic feedback makes it highly appropriate for virtual reality training. Sense of touch is important, so endoscope controls must provide force feedback. Particular function simulators Simulators for inserting a catheter, or seing veins together are further advanced.
