    摘要： A method and apparatus for simulating lung sounds in real time in an integrated patient simulator uses a manikin having an associated simulated lung comprising at least one bellows and at least one sensor for sensing the position of the bellows. Based on a physiological state of the patient simulator, a audible lung sound is directed through a plurality of sound output devices located at different locations on the manikin. The lung sound corresponds to an appropriate physiological sound at that particular location on the manikin and is synchronized with the position of the bellows. Synchronization occurs by continuously determining a volume of the bellows to determine a respiratory phase and a transition in the respiratory phase. The respiratory phase is determined by calculating a first derivative of the bellows volume over time and the transition in the respiratory phase is determined by calculating a second derivative of the bellows volume over time.

    摘要： An apparatus and method of simulating breathing sounds in real time involves the use of a manikin having a lung bellows. A sensor associated with the lung bellows is used to continuously determine the volume such that, using standard mathematical procedures based on the time and volume determined, a first derivative of the bellows volume over time can be calculated to determine the phase of the respiratory cycle (e.g. inhalation or exhalation). In addition, by calculating a second derivative of the bellows volume over time, a transition in phase of the respiratory cycle can be determined. Based upon the first and second derivatives of the bellows volume over time, a sound is output through an output device, such as a speaker, located proximate the mouth of the manikin. The outputted sounds are pre-recorded audible sounds of breathing corresponding to appropriate physiological sounds.

    摘要： An apparatus and method for synchronizing output devices related to a cardiac rhythm in real time in an integrated patient simulator during simulated medical surgery includes a manikin, at least one output device including devices for simulating a cardiac pulse and a radial pulse, a first computer associated with the patient simulator for generating an electric cardiac rhythm synchronizing pulse, a second computer for receiving the cardiac rhythm synchronizing pulse and generating a simulated response thereto, and a distributed processing network for transmitting the cardiac rhythm synchronizing pulse between the first computer and the second computer and for transmitting the simulated response between the second computer and the output device. In this way, a time offset to allow for simulated travel time or lag of the simulated cardiac pulse through the body can be added by the second computer where appropriate for certain subsystems or monitors associated with the patient simulator.
