  • Life support simulation system simulating human physiological parameters
    Patent number: 6273728
    Abstract: Method and apparatuses for simulating life support procedures in real-time using a mannequin. The apparatuses and methods are operable for a number of therapeutic interventions and provide for a number of appropriate simulated physiological and pharmacological responses. Included interventions are chest displacement, the application of gas pressure to the upper airway, inspiratory gas composition, administration of a fluid, or administration of intravenous drugs. These interventions provide a variety of appropriate responses (and misapplication of an intervention by a trainee provides a corresponding appropriate response).
