may I add that the HPS also includes respiratory mechanics and advanced monitoring options: Neither a ventilator nor a monitor will complain that no real patient is connected. Monitoring also includes such things as Cardiac Output determination and blood gas analysis. Ventilation allows modern support modes of ventilation but also the use of volatile anesthetics. Also more than 50 built-in Simulated Clinical Experiences (SCEs) are included together with complete documentation and references, debriefing proposals, etc. There is more to say to this simulator, please do not hesitate to ask if addtional information is required.
