ABSTRACT:
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.
