First Claim
1. A method of simulating emergency conditions as might be experienced in the operating room, including the steps of displaying from a memory simulated initial patient vital sign information representing a desired patient condition, modifying the vital sign information in accordance with one of a plurality of scripts, displaying a plurality of user input options, evaluating the input options selected by the user from the plurality of options in relation to preferred option choices in the script to determine the appropriateness and timeliness of the user responses, modifying the vital sign data in accordance with said script for improvements of vita sign information displayed if the user responses are appropriate and timely for return to the desired patient condition or continuing to display worsening patient vital sign information a critical condition in accordance with the script if the responses are inappropriate or untimely, providing a plurality of script blocks in each script, said script blocks being initiated sequentially representing worsening patient conditions, and passing to a lower script block if the simulated patient'"'"'s condition worsens and rising to a higher script block if the simulated patient'"'"'s condition improves, assigning a numerical value to each correct user selection or selections untimely made and progressing upwardly in the script when a positive threshold number is achieved and moving downwardly in the script when a negative threshold number is achieved, providing the user with a plurality of options, timing the user response time, transitioning through the script blocks in accordance with the evaluation of the user response time and appropriateness of the user choices.

Abstract
A method of simulating anesthesiology and operating room conditions including the steps of displaying initial patient simulated vital sign information from a memory to signify an initial patient condition, randomly modifying the displayed patient vital sign information according to a script matrix in a manner analogous to that in which a patient'"'"'s vital signs would be effected in the operating room by drugs and other external effects, thereby indicating a deteriorating condition, displaying user options, evaluating the timeliness and appropriateness of user input selections from the options in response to the changes in patient vital sign data, and causing the patient vital sign information to improve to its initial state or deteriorate to a critical state in accordance with the successive script blocks in the script matrix depending upon the user'"'"'s response and timeliness.

- 7. A method of simulating anesthesiology operating room conditions including the steps of displaying initial patient simulated vital sign information from a memory to signify an initial patient condition, displaying modified patient vital sign information in accordance with a first script of a plurality of scripts and thereby indicating a simulated deteriorating patient condition, displaying a plurality of user input options, interfacing options selected by the user with script, evaluating the timeliness and appropriateness of user choices from said options in response to the changes in patient vital sign information and displaying improved patient vital sign information or displaying deteriorating patient vital signs information in accordance with successive scripts in the plurality of scripts depending upon the inputs selected by the user from said options and timeliness of the user inputs, providing a plurality of scripts in a script matrix, said scripts being initiated sequentially representing worsening patient conditions, and passing to a lower script if the simulated patient'"'"'s condition worsens and rising to a higher script if the simulated patient'"'"'s condition improves, assigning numerical value to each correct user option selection within predetermined time limit and assigning a negative value to each incorrect user selection or selections untimely made and progressing upwardly in the script matrix when a positive threshold number is achieved and moving downwardly in the script matrix when a negative threshold number is achieved, providing the user with a plurality of options, timing the user response time, transitioning through the scripts in accordance with the evaluation of the user response time and appropriateness of the user choices.

13. A simulator for training health professionals to respond to mal-events occurring in a model patient, the combination comprising:
-
a display for indicating the condition of the model patient; input means for receiving the health professional'"'"'s response to the indicated model patient condition; means for storing a plurality of scripts, each of which simulates a mal-event occurring in the model patient, and each of which is comprised of a series of script blocks that store state data which indicates on the display a corresponding series of progressively worse model patient conditions; means for storing data associated with each script which identifies responses to the simulated mal-event which will improve model patient condition; timer means for measuring the time interval between the indication of a model patient condition on the display and the input of the health professional'"'"'s response; evaluation means coupled to the means for storing data, the timer means and the input means, the evaluation means being operable to score the health professional'"'"'s response to the indicated model patient condition and select a script block indicating an improved model patient condition if the score exceeds a preselected amount, and select a script block indicating a worse model patient condition if the score is below another preselected amount, in which evaluation means decreases the score as a function of the measured time interval. - View Dependent Claims (14, 15)
